Just add loads of the good stuff

Great news, the sun is shining, the builders are back, and things are happening. Although it was a little chilly this morning.  It has just dawned on me that I’ll be building my new garden in the winter.  Well, I always knew it, but from the balmy warmth of summer, all my imaginings were of nice days.  There will be nice days, once any frosts melt, but there will be less than ideal days.  When you have the luxury of an established garden, you can take the yucky days off!  But if you are on a timeline, then every day is a work day come rain or shine.  I think I may need to harden up.  If I thought today was a chilly start, then I’m in for a bit of a shock!  I see a shopping trip in my immediate future for good quality thermal clothing and wet weather gear.  I am determined to make that spring deadline.


Sand… what is it good for?

Once the builders do what they need to do with the house, we can move in and say goodbye to the caravan and the container and work on the garden can begin.  This is now being counted in days (could be counted in 2-3 weeks but counting it in days sounds better) so my days of scratching about looking for things to do is rapidly drawing to a close.   This time hasn’t been wasted.  I’ve learnt a lot, I’ve made plans – and changed them several times, and done loads of research that will be beneficial for the long-term life of this garden.  I am grateful for this last 90 days, because as the expression goes – ‘fools rush in where angels fear to tread’ and I was keen to rush in!


The builders have had fun digging the holes for the foundations… the second time wasn’t so much fun as the storm filled most of them back in!

A great example of this is how I am to treat this soil.   I’ve already learnt a lot about soil and plant science, but now we are at the point that really matters to me.   How is all of this relevant in my soil.  The general advice for sandy soil is to add loads of organic material and she’ll be right.   However, in my research I have discovered there this isn’t the case and there is much more to it!  Let me explain.

The problem with sandy soil is its size.  By definition a sandy soil has more than 85 percent of sand-sized particles and compared to the fine particle size of clay it is positively chunky. Depending on who you talk to the grains are supposed to be between .06 – 4.75mm.   This makes it porous.

Good soil

The new soil I had trucked in has loads of structure.

Unfortunately, this brings disadvantages.   As we learnt earlier, plants need their nutrients to be on a molecular level and dissolved in water, so it can get into the root hair.  But all of these lovely dissolved nutrients in water are more likely to woosh on passed and go right out of the garden and find its way into the nearest waterway.  And all the plant can do is stand by and watch as the gravy train misses its station.

To compound this problem, the large particle size has less surface area than other soils.   This is important because of the way nutrients are stored in the soil when not dissolved in the water.  Now we need to delve back into the sciency stuff, because soil particles have a negative charge and most nutrients have a positive charge and so they cling together like magnets until they do that monkey bar thing and let go of the soil and jump into the water molecules.  But with less surface area there are less rungs on the monkey bars so not everyone gets to play.  And if their not holding on tight they get washed away and all the potential supplies lost.


Where as the sandy soil is more ‘fluid’

The way to remedy this is to add the organic material and that combined with the poop created by the creatures of the soil, bind the sandy soil to create aggregates.  These become the sponges that hold the water, the desirable homes for the creatures to upgrade into and also increased surface areas for the molecules to hang on to.  These aggregates work together to form the structure of good soil.

So, it would seem organic material is the cure all so the more the merrier?  Well not exactly.  As sand is the foundational structure, it is always going to be more porous than other soils and good drainage is always going to be a feature.


If the wind gets behind it, nothing gets in its way.

Firstly – going back to the science, some of the key nutrients like chloride, nitrate, and sulphate have a negative charge and this makes it extremely difficult for them to stick around and they are more susceptible to leaching.   By some act of magic – actually there is science to explain it, but we don’t need to go there, the pH can improve or decrease the availability of the nutrients – too acid and some aren’t available, but others don’t mind, too far the other way and it impacts the availability of other nutrients.

And just to compound things, sometimes having too much of one thing can affect the availability of another – sort of like an overbearing kid attention seeking so the quiet sibling gets overlooked.  Look at me, look at me!  Temperature also comes into play and if it is too cold or too hot the availability of certain nutrients is affected.  There is more going in the soil than the office politics in a government department.


It gets everywhere!

Taking a couple of things into consideration – the porous nature of sandy soil, and the great work of the soil dwellers to make the nutrients available, and pH, the fine balance between too much and not enough, the electric relationship of the molecules, and the need for plant food to be soluble in water and the fact it can rain in quantities greater than the needs of the plant, it appears just adding loads of organic matter might not be the right answer.

Yes, it is needed, but adding it in great quantities at the beginning of the growing season and then maybe again at the end may be a bit hit and miss.  It would create a boom and bust situation where all of a sudden there is too much of a good thing, and everything would get out of balance.  Populations would flourish – excess nutrients (not a good thing) would flood the soil, the rains would come and they’d all be washed away.  Then the populations would starve and be in poor health and aggregates would crumble and the poor plants would come off worse than ever.


It isn’t a complete desert. Plants quickly regenerate on the exposed sandy soil.

Yes, adding organic material is the answer, but little and often, so there is a continual supply of material that can be continuously broken down in a seamless supply.  A good quality mulch would be a great idea not only retain moisture but give the soil creatures a raw material.  As the season wears on the mulch wears out – refreshing it often will be a good idea.   A little side dressing around the plants with some compost and well-rotted manure and feeding them with a slow release fertiliser will delay the inevitable leaching.  Regular soil testing wouldn’t go a miss in the early days to make sure things are doing what you want them to do.

Sandy soil

It isn’t all bad – there are areas about the place that look like this, which is promising.

When working with less than ideal soil you have to farm the soil.  Treat it like one of the crops.  I guess the expression cultivate the soil means so much more when you have sandy soil.    There is more to gardening than just the plants.

And that wraps up my understanding of my sandy soil – I need to nurture and support it like a good parent does with a kid, and it will grow up and make me proud.

Come again soon – things will be a lot less sciency now.

Chunky to Tiny

With the trauma of the recent storm behind us and any bad weather ahead of us already firmly blamed on the fact it is the school holidays because it always happens that way.  The moment they go back in a couple of weeks the sun will be shining and it will be the best conditions we will have seen in a long time.  The house has stood up to the conditions admirably and gives us such confidence going forward that it will be a safe home for our family well into the future.  I can let out a sigh of relief and return to delving into the wonderful world of dirt.   There isn’t much time left before I can get out there and get my hands dirty, so I’d better get a wriggle on, understanding how to use it well.


What is it with chickens and their need to linger near the door! I wouldn’t mind so much if they didn’t deliver the fresh packages on the path to the door!

Last time we explored they way plants like to receive their food, cut up into teeny tiny portions of a molecular size.  However, this is a far cry from the way we deliver it to them.   We lob barrow loads of compost at the soil, bucketful’s of well-rotted manure and handfuls of fertiliser and clumsily mix it all in with a garden fork.  Compared to the fine dining going on in the soil, our contribution is rather rustic and about as far from refined as could possibly be.

Kitchen waste

Nothing needs to be wasted. Today’s kitchen waste is tomorrows food!

So, the question to be asked this time is how does it get from chunky to tiny?  The common phrases we hear are it is broken down, nutrients are released into the soil and plants absorb them – as if by magic.  Now we know about the absorbing bit, so what is involved with the breaking down and releasing?   If we start by looking at the common things chucked into the garden to ‘enrich’ the soil, we can get an idea of what we are starting with.

Well-rotted manure

Gardeners are strange folk.  There aren’t many people that would delight in a trailer old of animal poop delivered to their door.  But this stuff would be similar to receiving a trailer load of gold dust to the right person.   But there are conditions.   It must be the poop of a vegetarian animal that grazed upon lands not recently sprayed with a systemic herbicide – some of these things can pass right through!  And it needs to be well rotted before adding it to the soil in the presence of plants.   Fresh poop still makes a great delivery, but you have to wait before using it and the best way is to pop it in a covered pile far away from any source of complaint and wait until it is no longer recognisable as what it once was.  Fresh poop can do more harm than good.  Once it is ready it should smell it a woodland floor and be nice and crumbly.


This is also a great addition to the garden to introduce organic material.  It can end up being a wonderful closed cycle in a well-run garden.  The spent crops are gathered up and put on the compost pile, the breaking down and releasing happens and what was once plant is now plant food and on the way to becoming plant again.

Natural Fertilisers

These are made up of ‘natural’ ingredients but more often than not, processed in some way, like blood and bone comes in a powder not in chunks of dead cow, rock dust is mined so it is a fine powder.  Fish emulsion doesn’t come with visible bits of fish.  It is to make it convenient for the gardener and also speeds up the process of making the nutrients accessible to plants.

Synthetic Fertilisers

These are purely man made to meet specific needs of the plant.  The nutrients are often non-plant based and sourced from mineral deposits and processed in a factory.   Sometimes seen as the bad guys in terms of delivering a healthy diet to the plant.  But the advantages are they can be pretty specific with the contents analysis, where the more natural products are down to the vagaries of what the animal ate or the quality of the soil the now rotted plant grew in.   These guys are often slandered as the fast food of plant world and not substantial enough for sustained growth.  But as we learnt previously – the plants don’t even notice where it came from as they absorb molecules far removed from how they started out and a magnesium molecule recycled though a chicken could be taken into the root hair immediately after one from a packet!  The plant isn’t fussy.

Septic system

It would seem there is no getting away from poop! This will be the marvelous system that takes care of it all for us very soon.

So, we now know what the food is predominately made up of, but how does it get small.  How is it broken down?  Well there is a fabulous process called mineralisation.  This is just a fancy way to say decomposition, but if you look at both words de-composite is undoing structure and mineralisation is making something into minerals.  But not wanting to over simplify things it is a complex process using a wide variety of soil creatures from the micro organisms that get to work once something dies, and start to break down tissue for their own needs, to the earthworms, bugs, beetles and other creatures that love to eat dead things.  In doing so the dead material gets broken up into smaller pieces so the bacteria and fungi can access a greater surface area.

It is like a medieval banquet where the room is filled with all sorts of people for the occasion. The king cherry picks the good stuff and the quality of the servings diminish depending on the status, right down to the dog running off with a bare boar bone.  At the end of the day there isn’t much left, however, the meal does reappear in a day or so in a different format and it doesn’t really matter if it came from a lavish throne or a humble origin it is one step closer to being mineralised.

Sweetie the Goat

Our beloved Sweetie the Goat passed away recently and we miss her terribly – she was such a delight. As much as I hate to think about it she is probably about to enter the mineralisation stage soon. I should plant a tree to remember her by.

This happens when the micro-organisms release enzymes that oxidise what is left from the ‘breakdown experience’ finally turning the chunky into tiny in a form plants can use.  There are other factors at play here, like synthetic doesn’t need as much help from the micro organisms in the mineralisation process but gets there all the same.  But there it is in a nutshell – it is all a bit of a giant feeding frenzy and a whole lot of poop broken down into every decreasing sizes.

So, adding loads of organic material and fertiliser should sort out my sandy soil….  Or does it?

Come again soon – we are almost at the point of knowing what makes my soil tick.

How bad can it be?

A few weeks I asked this question in jest in response to the winter weather conditions.   I now know exactly how bad it could be.  We have just been through a terrible storm and it would seem it isn’t called the ‘wild west coast’ for nothing!  Now I’m not naïve and I knew there would be strong winds, I just thought I’d have at least a couple more months to investigate the situation before winter conditions showed their hand.  It is very important when moving to a new location to find out as much about, not only the soil, but the climatic conditions and that was next on my list.

Rough seas

Some days it is like a mill pond out there and on the odd occasion it is like this. We’re not going to let a storm upset us – there are far more good days ahead.

But this week we have had a huge weather event, that seems to have even taken the boffins by surprise as there was little warning.  Either that or it wasn’t a slow new week, so their warnings were drowned out by the noise from other worldly events.  Somehow an Antarctic blast coming from the south became entangled in the lingering warmth of an exceptional late summer and got all excited.  There was thunder and lightning and heavy rain – although at least it wasn’t floody.  Most of the high places in the country were dusted with snow and for the rest of us, the temperatures plunged dramatically.  But what did the most harm was the wind.  My goodness it was wild.  Three days later it is still making its presence felt, but on Tuesday night it can only be described as terrifying. Especially when you live in a caravan!

wind damage

Our underfloor insulation is spread far and wide… you may find some in your backyard!!!!!

What makes it all the more terrifying is when your home-to-be is sitting up on thin metal jacks about 2 metres in air – facing the full brunt of the storm.  The highest gusts were recorded about 30 km up the coast from us at Manukau heads with a whopping 213 km per hour.   These were apparently only 10 km shy of the record for the highest winds we’ve ever had (well – since records began) So now we know – just how bad it can be.

wind damaged strawberries

My poor strawberries have been through a lot. I need to give them some serious love as it is still some time before they get planted.

The good news is, the house stood still and is a tribute to the Total Relocation Limited team.  They have worked so hard and tirelessly on the job.  But with our full support, work on the house has been put on hold until good weather returns.  It is very frustrating for us, as we are so close to the end.  But there are some things that just can’t be helped, and I would much rather have the team be safe and well than complain about our inconvenience.  What‘s a few more weeks in the caravan really, in the grand scheme of things?

Wind damage

I think I need to call ‘time’ on these peppers. There isn’t much point trying to save them when the season is pretty much over soon anyway.

But what it has brought to light is the worse case scenario, before we even begin to create anything.  This is a good thing.  As all the farmer neighbours have said in all their years they haven’t seen anything like it, I think it is safe to use this as a benchmark for any of my projects to ensure they are built to last.   I am rethinking the kind of greenhouse I will have as it clear an ‘off the shelf’ model just won’t do.   This turn of events makes the greenhouse project even more exciting and I am really looking forward to exploring options that will keep my seedlings safe in the spring.  But it isn’t just the greenhouse that needs careful consideration, the fruit cage, the orchard, even the washing line will need to be able to stand up to the conditions.

Wind damage

The tops of the grass have been windswept. Probably a combination of wind and salt burn. These lessons learnt early are important.

The general rule of thumb when moving to a new place is to wait a year before doing something in the garden to see what it is really like and to see what surprises pop up.  The surprises normally refer to the possibility of a magnificent display of spring bulbs, and not intending to mean devastating winds.  But I’m impatient and am glad I know now.  I am also extremely glad no real harm came to our home, our family and our team during such a terrible storm.

Come again soon – things will improve soon enough.

What’s on the menu?

When you think about human health, what we need to keep us going seems simple in some respects:  carbohydrates, proteins, fats, water, vitamins, and minerals.  But these can come from varied sources and our diets are a wonderful combination of so many things, so we get what we need.  I remember from my school days being taught that if all else fails, a boiled egg with wholemeal toast and a glass of orange juice would give you something of everything you need to start the day.  It was one of the few things from that class that stuck.


The way we gain sustenance is far more refined that anything else that needs nutrients for survival

But if you break it all down – carbohydrates are carbons, hydrogens and oxygens; minerals are naturally occurring chemical compounds like phosphorus, potassium, sulphur and magnesium.   So, while a grand buffet at a fancy restaurant may seem like a great way to satisfy all our needs – we aren’t that different from plants and what we actually need is food that is on a molecular level, so our cells can utilise it best.  But the beauty of it all is we can eat a wide variety of delicious things, so we can satisfy our tastes as well as our needs.

An egg

According to my 3rd form Home Economics teacher an egg has everything you need except fibre and vitamin C

Plants on the other hand aren’t so lucky and need just a few things on a molecular level.  The plants that give us wonderful things to eat are stuck with a very bland diet for themselves.  Plants only need a handful of ingredients from the soil.

The ones that get talked about the most are the NPK combo.  Nitrogen, Phosphorus and Potassium (we mentioned him earlier in the sciency stuff – he’s the K, just to confuse the already bewildered) These are the ones that get headline billing on bags of fertiliser, in the hope that the keen gardener will be able to work out which product is best for the plant.  But then you need to know what your plant needs and what state your soil is in before making an informed choice, otherwise you are just taking a stab in the dark and could be wasting your money and stuffing up your soil.  Over fertilisation can be a bigger problem than under fertilisation.   This is why we need to know about these things.

Green peas

Green is such an important colour for plants, but then again so much of what we eat comes in such an amazing array of bright colours.

Nitrogen (N) generally originates from organic material and is what makes strong shoots and leaves and makes healthy foliage.  Although, depending on what you are growing, too much can come at the expense of flowers and fruit.

Phosphorus (P) is mineral from inorganic sources and helps the plant grow strong roots and we have already learnt the importance of strong, healthy roots.

Potassium (K) is also a mineral and plays a big part in plant reproduction – flowers, fruits and seeds.  You really don’t want to lack this in the veggie garden or the harvest wouldn’t be all that great.


I still marvel at how such a complex and deliciously thing like a raspberry is the result of a handful of ingredients.

There are three other important ones that make up a huge part of the plant, Carbon (C), Hydrogen (H) and Oxygen (O) but the plant has no trouble getting hold of these, usually from the atmosphere to use in photosynthesis, that they are hardly even counted as the essential nutrients for plants.

But the plant diet is a little more varied than just these top six.  There are others.  The secondary elements, the plant needs them, but not in great quantities.  However, they are essential for plant function and if they are lacking – for whatever reason, remember it doesn’t necessarily need to be absent from the soil, but just being too cold, or some other excuse, for the plant to take it up, the plant has ways of letting the gardener know.  Nutrient deficiencies show up in the leaves like some kind of code – from yellowing leaves with green veins, to purple leaves, to patchy leaves to stunted and munted leaves.  Each deficiency represents in different ways.  It is a bit like a pregnant woman screaming out “I want ice cream and I want it now!”  And if you know what is best, you go and find ice cream straight away!


Have you ever looked closely at your food and seen the intricate details?

So, these secondary elements are Calcium (Ca) and this is important for making strong cell walls. Sulphur (S) is involved in making chlorophyll, the thing that makes plants green, so it is kind of important as most plants are green!  Magnesium (Mg) has an important job in the photosynthesis process so you really wouldn’t want your plant not to have access to this.  But of an interesting note too much chicken manure in your soil can interfere with the availability on Magnesium.  Which is another reason it is important to know all of this stuff.  It is so easy to take handfuls of ‘good for the soil’ things and lob them about like it is some kind of lolly scramble, without realising you aren’t actually helping.

sliced cucumber

So much going on in each slice

Then there are the Trace Elements.  Plants need them but in minute quantities.  The plant will let you know in its leaves if they are lacking, but absolute care must be taken when adding them to soil.  You can’t unmake the sea salty.

Boron (B) has a key role in plant growth, so it is pretty important.  Without it you can end up with stunted growth.  Iron (Fe) and Manganese (Mn), like Sulphur are gainfully employed in the production of chlorophyll.  Copper (Cu) and Zinc (Zn) work closely with enzymes to make things happen.  Molybdenum (Mo) is a little-known nutrient that helps the plant convert nitrogen into more plant friendly forms and so the smallest nutrient is essential for the use of the largest.

There are a few other teeny tiny ones that are hardly worth mentioning and from what I can understand aren’t all that problematic or they would be higher up the list.


Plants don’t get cake…. poor plants.

So if you look at it like a high school social structure – you have the popular kids, N, P and K – everyone knows about them and think they are important.  They get talked about a lot!  Then there are the kids everyone seems to like and get on with, but at the same time they are just average and ordinary and no one notices them.  The poor C, H and O’s.  Lost in their ease and abundance.   The sporty ones – the secondary elements – they make the school look great – or not if they don’t do well and everyone notices them when they win or when they lose.  The rest of the time no one really thinks about them, out there in the field, doing their thing and practicing all the time.

The trace elements have to be the geeks and the nerds.  Their importance is barely noticed but without them there would be no school newsletters, no librarians, and no one to do all those volunteer jobs everyone else loves to hate.  I have to confess back in the heady days of school I was a trace element and found there were certain privileges being in the science club that the more popular kids had completely overlooked – like being inside at lunchtime on a rainy day, for one!  And ironically Nitrogen can’t be without Molybdenum doing its homework!

Empty plate

A sign of a good meal is an empty plate

And that is what a plant needs in it’s daily diet to stay healthy.   But we are still looking at things in a tiny molecular level and it is still a far cry from shovelling barrow loads of compost onto new season soil.  So, the next question is, who chops up the plant food into bite sized chunks?

Come again soon – we’re almost there in this journey and then I can start digging.

Welcome in

Over the last week we got a bit side tracked from the study of the soil, what with Easter and April Fools – I think my 24 carrot gold seeds were a bit too subtle… maybe I should have spray painted 24 carrots gold!  Anyway…. The other exciting distraction over the last week is the house has arrived, but I’ll share more of that with you later, because I really need to press on with this soil science stuff. The arrival of the house has tightened the timeline, because as soon as they have finished sticking it all back together and council signs it off, then we can move in.  That will mean the caravan and the container can go, and I can start my garden.   So, I’d better know as much as I can about the soil before I get started.   So where were we…

sowing seeds

What a great view to have while sowing seeds. Just the thing to take your mind off ions and osmosis!

In order to understand my new sandy soil, I have been trying to understand how the plant works and how the soil works so I can make sense of it all and be a better gardener in less than ideal conditions.  Last time was like the bit in a scary movie, where they are crossing a dangerous rope bridge and the hero wants to go fast to get across as quickly as they can, but needs to go slow and examine each tread so they don’t fall through.  I feel like we have made it passed the horrible bits and are now safe of solid ground.

milk bottle plant labels

I love to use my upcycled milk bottle labels. I also like to sow my seeds in alphabetical order.

So, we know water is a great carrier of nutrients up into the plant, through the xylem, and the root cells have good systems for managing the nutrients once they get in.  And we now know the nutrients need to be tiny – on a molecular level to get in.  But the question remains:  how do they get in?  They don’t have arms and they’re not a sponge and don’t go about sucking up everything arbitrarily.   It turns out the plant is very particular as to who and what it invites inside.

Sowing seeds

I also like to take photos of the seed tray, just in case something happens… like forgetting how the alphabet works and sowing cabbage before beetroot!

There are a couple of ways this happens down deep in the soil.  One method is passive, and the other is active.   The passive process occurs through a process called osmosis which is a kind of popularity contest for ions (the molecules with the electrical charge).  Basically, they want to be at the exclusive party and all mill about outside the cell in high numbers, being absorbed through the semi-permeable cell wall into the cell where there are low numbers.  The numbers are kept low as once inside the ions that are needed are escorted off into the heart of the root, across the cortex and beyond the casparian strip, and are locked into the plant and able to be used where needed.

Sowing seeds

I’ve sown the seeds thicker than I normally would as they haven’t been kept in ideal conditions recently so I’m not sure how the germination rates will be.

However, the water is trying to control this movement and prefers things to be balanced on both sides so won’t let everyone in.  If too many ions get in, it becomes too concentrated and the process reverses and the ions leave the cell like it is yesterday’s news.   So, there can be a lot of coming and going in the root hair cell.

Sowing seeds

I hope these peas do well as I love fresh peas. I’ll take the weakest of each pair out when the time comes to avoid overcrowding and fungal disease

This is all very well if there are large concentrations of the ions needed lingering in the soil the roots are sitting in.  But not all of the ions are there in large enough numbers to just drift in and have to be delivered into the cell like a VIP in an active system.  The cool thing about plants is they have a process for everything they need and even create their own energy currency ATP (adenosine triphosphate for those who want to know).  It is made in the respiration process up in the leaves.


Less than a week later and I have some little green babies. I do hope there will be a garden to plant them into soon

Apparently, it is not known exactly how this works, but the cell walls of the root hairs have different carrier molecules embedded in them that recognise specific nutrients.  Sort of like secret entrance ways and the energy from the ATP is used to bring in these nutrients against the concentration flow so the plant can get what it needs specifically.


The tomatoes are still going strong.

I sort of see it like the DJ and the magician turn up to the party and is stuck in among all the party goers out the front.  The party goers are having their tickets checked and allowed in so long as the party isn’t overcrowded on the inside.  But the DJ and the magician are special and need priority treatment to get in and with the assistance of some currency to grease the wheels (ATP) they are whisked in through their own separate entrances.


I may not have much success with gold carrots but my saffron has come back so maybe I’ll get rich that way.

However, this system has its limitations.  If the temperature isn’t right and it is too cold or too hot, then the doors don’t open, so the DJ and the Musician have to wait outside for it to warm up.  Meanwhile the party goes on without the talent.   This can be seen in many common plant problems – if it is too cold phosphorus can’t get in and without it the plant turns purple.  Or blossom end rot in tomatoes – it is due to a calcium deficiency and in most circumstances, it isn’t because it isn’t in the soil, but it is too cold to get into the plant and so the nasty rot problem occurs.  This is why it is more common earlier in the season, when it is still a little cool and then comes right.

relocated house

And finally here is a quick view of the house as it was earlier this week. We’ll be in before you know it!

But even the passive system has something to teach us…  if there aren’t enough nutrients in the soil, the ones already in the root hair cells have no choice but to leave, so they can hang out with their friends until the numbers become more concentrated that they can flow back in the other direction back into the cell.  It would seem balance is the key to ensure the plant stays consistently well fed, not yo-yoing between feast and famine.

And that seems like enough to take on today.  It would seem information uptake into my head is also limited by concentration levels.

Come again soon – I think we need to find out more about these all important nutrients.

As good as gold…

I am always up for a challenge and when I saw these fancy carrot seeds I just had to have them. They weren’t cheap, but I think it will be worth the investment in the long run. Germination can be a little tricky but so long as you don’t sow them too thickly it should be ok. I’ve used 24 seeds and I’m hoping for the very best!

24 carrot gold seeds

Carrot Gold seeds are really quite pretty.

This April is all set to be an awesome month, and we are starting it off with half a house and will end it with so much more.

Come again soon – there is so much going on, I’m not sure where to start.

Collecting apples for crushing

Currently, in my gardenless state, any opportunity to get up close and personal with any kind of gardening and I’m in.  Even a rain soaked autumnal day won’t dampen my enthusiasm, so when I was invited to help pick apples and help get them pressed for cider making I jumped at the chance.  I even dragged Hubby the Un-Gardener with me as being cooped up in a caravan on a rainy day is never ideal, especially after 64 days!

A handful of freshly picked apples

A handful of freshly picked apples

The weather had been good pretty much all week and was lovely since, but that day just happened to be the soggy one.  I was worried they would cancel it, but they are like minded folk with a burning passion for making the most out of their land, exploring possibilities to as far as they will stretch. A spot of rain is not an issue. It was motivating to be with them and made me all the more eager to start my garden.

Gardena Fruit Collector

If you need to pick up the manky apples under the trees, the Gardena Fruit Collector makes it so easy and less messy

We drove down to the back of the farm past all manner of edible crops, fruit and nut trees, pigs and cows.  If I was to have a farm like that, that would be the kind of farm I’d have.  But I’m more of a plant person and managing plants is a lot easier than managing animals.

Gardena Fruit Picker

The Gardena Fruit Picker – apple picking without having to climb trees

You could see the orchard from a distance as the greenery of the trees was dotted with the red of ripe Gala apples.  As the orchard was at the far end of the farm, it reminded me so much of my old orchard at the far end of our old place.  The grass was long, and the fruit wasn’t quite perfect, and I felt so much at home there.

Gardena Fruit Picker

The long arm of the Gardena Fruit Picker made picking those hard to reach apples easy peasy.

The first task was to clear away all the fallen fruit, so it wouldn’t be confused with the fresh fruit that was soon to be shaken from the trees.  All but the very rotten was picked up and put in buckets for the pigs.  It was a good thing I’d bought along my Gardena fruit collecting tools as the Fruit Collector made short work of this job as the icky fruit slipped easily through the flexible wires.  Hubby the Un-Gardener nabbed this tool and so I was left rummaging around on my hands and knees, picking up smooshed and the pecked fruit.  I looked across enviously at Hubby the Un-Gardener who was clearing up under trees in a great rate of knots without so much as getting his fingers messy.

Bring in the apple harvest

With drops of rain beginning to fall, we carried our heavy harvest from the orchard

But it did speed things up, as the clouds above were heavy with rain and a new downpour was threatening to make things unpleasant.   Once the ground was declared good to go the trees were given a good shake and the ripe fruit came crashing down.  Once again Hubby the Un-Gardener leapt into action and quickly swept up the fallen fruit and the crates were filled fast.  There was stubborn fruit that refused to fall and there was something satisfying, to reach up into the branches and pluck armfuls of apples, visibly clearing the tree of its crop.

Apple crusher

Very creative hands built this apple crusher

As we stood back and admired our mornings work, the heavens opened, and the rain came down.  There was nothing else for it but to load up all we had collected and return to the farmhouse for wonderful shared lunch.  The homemade pea and ham soup seemed perfect for the day.   Shamefully my contribution was not lovingly crafted by me, but by the good people in a food factory far far away.  It is just too hard to do that sort of thing in the caravan.  But just wait until I get my new kitchen – oh the things that will come out of there in the months and years to come!

Apple press

The homemade press was also a thing of beauty.

The highlight of the lunch was to sample the cider, from the orchard, from the previous season.  It was so light and refreshing, although I could feel a slight kick coming over me.  Just as well we were rounded up to take the apples to the next level.   The set up was a dream cider making operation, with everything hand made or put together by our friends.  An old bathtub at a good height was filled with water and the apples were washed and scrubbed and any rot, coddling moth or particularly manky bits chopped out.

Apple waste

Out there somewhere, are some very contented pigs.

They were then put into the amazingly crafted handmade crusher.  There was a therapeutic action to lifting the lid to add the apples, then allowing the weight of the lid to press them against the wooden drum studded with screwheads to turn them into pulp.  A frequent addition of melted bees wax kept the drum lubricated as the small motor kept it all spinning.

Apple Juice

This apple juice is about to be transformed into something wonderful

From there the pulp went straight to the press, where it was stacked between boards in cheesecloth wrapped bundles, five high and gently squeezed with the aid of a car jack.  The juice was encouraged to pour from the fruit and was the sweetest I’d every tried.  Once squeezed dry, the flattened pancakes of fruit were put aside for the lucky pigs and the juice was taken away to begin the fermentation process.

Cider crusher

And the reason we go to all this effort is for a very fine drop of lovely cider

It was such a lovely day and we look forward to the day we are invited back to sample the fruits of our labour.  It also made me keen to begin to think about the trees I want in my new orchard.  Soon it will be fruit tree planting time, so I should give it a little thought.

Come again soon – we’re still looking into this dirt thing as bite sized chunks make it so much easier to understand.

Soaking in the Science

I find if I want to figure out how something works it is important to know everything.  I’m not very good at accepting things at face value if it means I’m not quite clear on how it works.  Except possibly the remote control on the TV.  That is way beyond me and I freely admit to asking the kids to switch it from X-box mode to my favourite TV channel so I can watch gardening shows (when they are on, they can be a bit few and far between on our screens – and also when we had a house… oh the good old days!   But we’ll get a new one soon enough).  When it is something I’m deeply passionate about, like the garden, then settling for a casual answer just isn’t enough.  I need to know how and why, so I can be a better gardener with my new, vast quantity of sandy soil.

Nigella Love in a Mist

Hopefully I won’t lose you in the mists of science so I’ve added pretty flower photos in between the heavy chemistry to lighten it a little, like this Love in a Mist

Sometimes this takes us to easy places, like the straight forward plant biology, but it can take us to the scary world of chemistry.  Chemistry was never my strong point – it is like maths in disguise.  But I need to push past school days trauma and dig about for the answer to “how does this absorb thing actually work?”

Deep breath….  Here we go…

Last time we discovered the intrepid root hair cells that get out amongst the soil, risking their fragile lives to hunt and gather the moisture and nutrients the plant needs.  But it is all very well to say they absorb or gather,  The thing is, they don’t ‘go about’.  They are fixed, anchored – rooted to the spot.  So they have their outreach as far as their root hairs will go.  Generally they aren’t seeking anything out.  They are more like the filter feeders of the ocean, like mussels and oysters, glued in position and hoping what they need comes by.   They don’t go cracking open soil particles looking for what they need.   And remembering the root hairs are microscopic single cells that take on the nutrients, then you need to consider the nutrients need to be really tiny, much smaller than the handfuls of fertiliser, compost, manure or other things you scatter about the soil between the growing season to enrich the soil.  Things need to happen to that to make it accessible, but we’ll talk about how it goes from chunky to tiny another time.  What we need to know now is about the tiny nutrients and how they get into the plant.


Alyssum is one of those overlooked filler plants, but it has a wonderful scent and on closer inspection it is really quite sweet.

Technically nutrients are broken down into atoms and molecules.  So going back to school chemistry – if you remember the periodic table – a colourful chart where most things have a short ID of who they are like C for carbon and N for Nitrogen, but others are just odd to confuse bewildered students like Au for Gold (what’s that all about? – it isn’t like G isn’t available or Go for that matter) and K for Potassium.  Well this is a big list of all the chemicals in the world (which are atoms, and are the smallest form of chemical, from what I understand) that go together like Lego to make up everything in the world.  It doesn’t matter if it is organic or not – everything in the world can be broken down to a collection of these individual things.


The Foxglove is just as beautiful close up as it is from a far

The atoms are joined with others in amazing combinations to become things. They are joined together with electric bonds.  If you go back to the periodic table, each thing has a number which tells you how many …

Oh my goodness we have to go deeper – each atom has a nucleus, which is the main bit of it and in it are protons which are positive and neutrons which are neutral and then it has electrons, which are negative, around it – kind of like the planets around the sun.  Now depending on how many of each the atom has ultimately determines if it is a negative atom or a positive one. Which determines who it can hangout with to become a molecule.  (still sort of like the Lego block – still made of something but that ‘something’ (the plastic) if you broke that down it isn’t Lego anymore, but also looking at the Lego block – does it have two bumps or six?)

Manuka Flowers

Manuka Flowers on mass are a sight to behold

Did I mention I don’t like chemistry? – well I hope I’m not losing you as I’m in danger of losing myself here.  But this is important because these atoms join together – electrically with their electron glue.  I could go deeper into this but it is complicated.  But essentially it is like a jigsaw – some fit together and some don’t.  Plants need ones that are water soluble so they can easily join the flow of water through the plant via the xylem.  If you think about it – the two hydrogens and the oxygen in water are like three kids dancing in a circle and then others come in and join them and the song changes, but there are some kids they don’t want to play with.   But also there is a limit to how big the circle can be so even some of the ‘right’ kids miss out.  Ie the water can become too saturated with the chemicals and limits the amount that stays in solution.    So even on an atomic level you can have too much of a good thing, so over fertilizing is a wasted effort. The number of kids that can join in is also affected by pH and temperature which is also something to take into consideration when feeding your plants.


Sometimes the large heads of flowers like hydrangea can be taken as the source of beauty, but if you look closer there is some pretty cool things going on there too!

Ok so you have these chemicals – now molecules, which are groups of chemicals joined in a way that makes them able to join in with the water chemicals to become soluble, sloshing about in the soil.   Well not quite sloshing because as all things have this electrical charge, either positive or negative, then the chemicals are hanging around with the soil chemicals and the water chemicals attract them over and like hanging off monkey bars in the playground they swap one rung for another.  The root hair can’t take on soil particles but can take on water.   But how?


You can’t go past the simplicity of a daisy without a smile

Ok – I don’t know about you, but I need a break here.  I don’t enjoy chemistry and I’m sure my old science teacher would look at my explanation and roll his eyes – but I’m not sitting an exam here and a vague understanding of the horrible bits is good enough for me.  But we are safely through that bit and how the nutrients get in is kind of cool – once you know about the horrible bits.

Come again soon – for the actual how it gets in.  I hope this is making sense to you.

Sweet Chilli Goodness

I don’t know about you but I needed a break from all that heavy sciency stuff.  You should see what I have been looking into for us next!  I do have to say it has been a great distraction from the fact we still don’t have a house.  There have been a few delays – which to be honest was probably expected.  Either way, the house will arrive soon and it will be much cheaper and much quicker than building a house.   So I’m not complaining.


It is nice to be able to harvest something in this time of no garden

So while I wait, when I’m not losing my head in science, I’ve been processing my chillies from my container garden.  There weren’t great quantities but enough to entertain me for an afternoon.  We just don’t have the facilities for a glut right now.  I decided to take you all with me in my cooking in the caravan arvo and I had a lot of fun. You can check it out here:

It is a great recipe, and really easy – even easier if you have a blender!  So I hope you give it a go.

Come again soon – we’re back into some heavy science stuff to pass the time.

The root of the problem

On my journey to understanding my sandy soil from the plant to the soil, we have already found that the plant pretty much sucks up the water from the soil and releases it out of the leaves as water vapour in some kind of super pump delivering the nutrients along the way.  There are other uses for the water in the plant, but we’re just interested in the bit that connects it to the soil.


Roots do a good job of stabilising a sandy hill to prevent erosion… except when chickens undermine it to dust bath in the warm sand.

The common line is ‘water and nutrients are absorbed from the soil’ but that isn’t good enough for me – I want to know how. Some soils are better hosts to this process than others and so if we understand how this happens then we can treat our soils in ways that can help and not harm the process.

This means we are still looking at the structure of the plant down in the roots, but there is also some chemistry in there and other complex scary sciency stuff, but if we step back and look at it in a more user-friendly way, it might make more sense.  If we think of it in a space type action adventure, then it is even more interesting.

Washing carrots in puddles

Maybe I should install a sink in my new garden so I don’t have to wash carrots in puddles!

In the centre of the roots is the up and down elevators to the plant above with the phloem bringing the manufactured sugars down and if they are bringing them as far down as the roots it is likely to be stored for future use, like in spuds, carrots or turnips. Beside that is the xylem which whisks the water upward taking with it any nutrients that have been ‘absorbed’.  This is wrapped with the endodermis that has within it the ultimate gate keeper as to who can enter the xylem and who can leave the phloem – the Casparian Strip.  Like some kind of bouncer protecting the VIP area in a nightclub.  And there goes my space analogy already…  maybe it is like some kind of specialist Storm Trooper protecting the access way to the heart of the Death Star?  I don’t know – my kids are the Star Wars experts.  But the endodermis with its embedded Casparian Strip wraps around the pipes to create what is known as the vascular bundle and you can only get in if you’re on the list.

Sweetcorn roots

When you dig up plants at the end of the season it is useful to have a good look at the roots so you can see how they grow, so next season you can make the ground ideal for their needs.

Beyond this central core is the cortex which has large cells that can be thought of like some kind or foyer or waiting room.  The sugars from above can be stored here as starches but it is also where incoming waters and absorbed nutrients are escorted across the root as they make their way across the cortex to the vascular bundle as they await permission to head on up into the interior of the plant. In my head I see some kind of secure government department that once you clear the front doors you need some kind of staff member with a clipboard and a name tag dangling from their neck to take you to where you need to be.  (I’ve never been in a place like that but seem something similar in the movies.)

Chicory roots

Oh… the time I tried to make chickory coffee… Yeah Nah, won’t bother with that again. The flavour was ….. ‘interesting….’

Beyond the cortex is the epidermis that wraps around the whole lot in a waterproof layer in a single layer of cells.  But not just any kind of protective layer – it has special cells with special jobs.  Like the leaves it has stomata cells that open and close to allow gas exchange.  But it is the root hairs we are interested in as these are the ones that do the ‘absorbing’.

The root hairs are single cells that elongate out from the epidermis along the length of the root and its branches and are the ones responsible for the all-important water and nutrient absorption.  These cells are the hunters and gatherers of the plant cell community.   They are microscopic, fragile and only last a few weeks, but the epidermis cells are constantly being replaced.


If you want ugly roots, you can’t go wrong with celeriac. But they taste good so they can get away with it!

And that is the biology bit of understanding the soil.  Giving myself an overview in my head I see these intrepid individuals (root hairs) risking life and limb going out to seek out the essential elements for life for their civilisation.  These nutrients are then thoroughly checked for suitability and demand and then whisked up into the heart of the community on a wave transportation not dissimilar to being teleported to where it needs to be in some hi tech mail room organisational system, with the water being little more than the mechanics of the transport rather than essential in great quantities for hydration – although it does have essential for life uses for a portion of it.

Onion roots

These onion roots did a great job of providing for these onions. That was such a great crop.

So, you can sort of see some kind of space action movie thing going on… well it is a bit weak, you hopefully you get the picture.  There are so many more amazing things going on in the plant to make it the functioning being that it is.  But I’m just focusing on how it is connected to the soil.

Come again soon – because we now know how – but want to find out more about this ‘how’ business as ‘absorb’ seems a bit wishy washy to me.
