It grows and rises up!
I've been converting the 'beds' into mounds of various sizes.
Thus the growing space has grown significantly and the photosynthesistic joy is self evident. I use fewer pots per area and since the garden comes up to meet me, I don't have to bend down so far.
I find I can hose fill uncovered pots even when standing at some distance from them.
Note the paving --old woollen carpets -- and new potting work station.

Thank you, Dave for explaining so clearly with words. Garden builds and diggings have always made me think. As I grew up on a large strawberry farm, our beds were long built up rows in a straight line with a double row of plants covered with sawdust. My question to my father was why they were not in spirals and heaps. He had no answer.
Your garden reminds me of ancients gardens where the people had large buried terracotta pots holding quite a bit of water, and allowing it to seep into the ground and surrounding plants.
You have taken it one step further. Great work.
Christa: Are the mounds in different widths and heights?
Yes. I'm experimenting with size, but different plants suggest different heights. I cannot say for sure one size fits all. The question is the reach of the moisture from the pot or the ability of the plants' roots to travel toward the pot's damp zone. A lot of research done in India on this with stats on depth and circumference of water reach varying per soil type.
They appear to be in rows in the photo's.
They appear in rows only because I'm converting beds into mounds.I've got them every which way in the main. When you change the sizes one from the other you end up with mounds growing without a pattern. But I also experiment with pattern and batches:
Two together;
00 -- the camel.
The five'o
0 0
0
0 0
...as the valleys are as important as the hills.
But generally I make my sand castles where impulse dictates as I can always move them about later. And, true to the beach tradition, I use a hand trowel to do itHow many perches of land would you have as mounds.
How many perches of land would you have as mounds?
I'm converting the whole veg garden to mounds...and it's a big garden. Some 'flats' still remain while I wait out those spots to harvest. Generally though the garden is a succession of hillocks. Looking at the mounds in the beds , I thought yesterday I'd start taking out some of the path and insert a few mounds half way along that, like a cul de sac. The ruling element -- methinks as I pondered this prospect -- was the reach of the hose and the filling of the pot.
All the main corners on the paths have poles -- flexi tent poles -- around which the hose drags as I water the garden. So if I can get a hose to within cooee of a pot I can fill it so long as I have line of fire.
In this image below, the area in focus has maybe 10-12 mounds. So it's very space efficient.There are pole beans, cucumbers, tomatoes , zucchini, potatoes, spring onions, huauzontle, kale, chicory, endive...and other plants in all that jungle. Thats' one section which happens to be defined as a square. You need to know whats' in there and when it is ready to harvest of course. Stepping between the mounds and navigating the valleys is the way to traverse the area.
Compared to what it used to be -- 3 beds, traversed by two paths -- it is stunningly more productive with much better growth and irrigation.
You cannot afford to be anal I guess.
In this image below -- of a particular bed conversion -- I've created smaller mounds both as an experiment and because I'm growing spring onions along with other stuff. In the valleys there,between the mounds, I've planted out pigeon peas for Summer shading.
The naked tree is a frangipani...
But there's also some creepers in the mix -- to harness the railing (which I have repaired since maybe a possum and dog urtication pulled it down).
The smaller mounds seem -- touch wood -- to handle root veg too -- carrots, radishes, turnips -- but I cannot rule on that. That's a work in progress. The root veg need a pretty consistent water supply so I'd not expect big mounding would suit them. I hope to plant out a few mounds to root veg to see what gives.
The trick being -- I'm hypothesising -- that you plant our your root veg at the top of the mound around the pot...and other plants down the slope.
Thats' still a work in progress: plant what veg at what contour as I have deep valley, mound sides, crests, sunny sides, shaded sides...to choose from.
But the main thing is that, thus far, i'm getting better harvests form these hills than flat land gardening. I did raise up the beds a tad originally, as we all do, but when you mound you bump the soil skywards keenly. I also dig down when I build the mounds and shovel out that dirt too with the plan that I lay down paper, plants cuttings and other mulches in those trenches to hold water and, in time break down to add to soil fertility.
I'm also planting those trenches with pigeon peas, cannas, some spinach creepers like Warrigal Greens and Brazil Spinach, Dog Bane, Pigface (although I locate them up the hills a bit), aloe vera....
Just on the Pigface (and it should also apply to the aloe vera) with all this active conversion I'm engaged in, I'm harvesting the pigface, chopping it up and adding it to the soil I build the new mounds with. It will be interesting to see if the desiccated pigface adds to the sandy soils' water holding capacity.
Go to the top page here and under SITE TIPS in the side panel to the left, search 'mounds' or 'garden mounds' .
I also had a bush turkey problem...but I cannot say if they are reproductively aroused by readymade mounds.
However, the question is why would you want to create a mound-- with a pot on top -- if your current habits worked?
All roads lead to Rome...
The question is productivity vs water usage vs space under cultivation.
Mound gardening sounds very interesting. Are the mounds in different widths and heights. They appear to be in rows in the photo's. How many perches of land would you have as mounds.
My problem would be our local bush turkeys that go around putting their beak in the heaps of soil in my backyard and checking the temperature for a suitable residence.
I'm just musing really -- trying to explain why what seems to be happening, does occur.
But the proof of the pudding is in the eating.
But for background, here is an original inspiration that I adapted. It relies on water rising up from the valleys between sculpted ridges. Although the example coats the ridges with lots of stuff like hessian bags and newspapers as well as straw mulch.
When I came to experiment I could not make it work at all because my sandy soil was so friable.
After using the pots for a few years I kept worrying about how best to place them for improved efficiencies. After studying Polynesian, Melanesian and North American Indian gardening design, building mounds -- as they do traditionally -- began to make a lot of sense.
However, there is one rider: after years of mulching and fretting over my soil, what I'm doing is mounding up the best of what I've created into singular piles. So I'm not starting from scratch. That means instead of having to put up with a shallow layer of DIY loam sitting atop the sand underneath, I've deepened the 'beds' by layering the good stuff into a series of hills.
And every time I replenish the mounds , each year or whenever, by digging at the base and shovelling the soil uphill, I'm moving good loam back up to work for me.
Yes -- thats' the trick, Florence; the 'ollas' (aka terracotta pots with dinner plate lids)
...and the mulch coating holds moisture on the surface as the plants establish their roots. So you gotta plant out the whole knoll preferably. But then 'run off' isn't that much of an issue if at the base you have mulches(and clays?) that slow down and hold the water at the level of the bottom of the hill. So like a 'wiking' bed that moisture is (hypothetically says I) available further up the hill by hydroscopic cohesion processes that are married with water reservoir in the embedded pot.
You could do the whole thing just by irrigating the base of the mounds -- and not using the pots --if you could ensure that your soil would hold onto the moisture there.
An occasional splash of water over the mound keeps the process working as it would keep seedlings alive..
I do get settling -- as it is sand afterall and with the build the sand gets fluffed up, but there isn't much erosion despite the weathering.
I think tahts' due to
Bet you young locals wouldn't know what referdex is either :P There's GPS in cars, and smart devices so prevalent, I wonder could the new generation still read street directories any more ^^"
I think the moulds work well with your ollas ~ moulding didn't work well for me before with water run off
Sure, Lissa...But who knows what may happen outback in way of gardening developments? You can indeed make a mountain out of a mole hill. Every fiddle here or there suggests some other possibility.
Very plastic is sand. And with me being a frustrated sculptor ... it's all an excuse to be hands on.
Only yesterday I targeted a spot for another extra big Sweet P mound...and since I've taken more carpet out of the house my wool pathed thoroughfares are looking like a 'Referdex' (huh! Bet that term will test anyone's local roots!)

Looking good Dave. When you're ready you might like to have the group back to show them your efforts first hand? Many people would be interested to see what you are doing.
I will also try to plant sweet potato in my Trad/compost mounds. I am a little worried about the rabbits and wallabies at my place though as I'd imagine that the leaves will be quite appealing to these critters especially as the grass around is very dry and almost crunches as you walk around at the moment. I guess the constant nibbling will keep rampant growth at bay and may help with tuber formation. I dream a lot!
