No-Dig Garden Success
I have been trialling a new-to-me form of gardening this last year, a no-dig system where the soil is always covered with compost and mulch, and the soil itself never sees the light of day, just as the soil in a natural system like a forest is always covered up with plants and twigs and leaves and animal poop. The benefits of this system are showing themselves in the happiest crops I've seen yet in my garden. The corn is as tall as I am; actually, this is not such an achievement, as I am not very tall, but the beans behind the corn have grown off the top of their 2m tall trellis and have just kept going, and are now wrapped around each other and waving in the breeze.
Zucchinis are ridiculously prolific as are the cucumbers, both of which have to be picked daily to prevent them turning into monsters.
The tomatoes are giant, still green, but very much bigger and more lush and pest resistant than last year's crop. Also, far less weeds are growing because the mulch is depressing them. Every few weeks I do a bit of weeding then shovel on some more mulch and the weeds are starting to give up, which is rather surprising as my garden is a jungle of weeds, with the vegie garden carved out of the centre of the wilderness, so the fact that weeds are not getting a foothold here is amazing. Last summer I more or less gave up and the kingdom of weeds took over. Here is the tomato patch: small, but prolific.
Everywhere in these photos that you think you can see bare soil, you are actually looking at compost applied about 10cm thick over sheep and chook manure and some crushed rock minerals.
Here are my spring beds that I have just cleared out to replant for winter. I had to build up the sides of the beds with more bricks to fit in all the extra organic material going on top. Once upon a time I would have dug the soil over between crops, but this time, a bit of weeding, and lots of manure and compost. The compost is a reasonably woody organic compost that I had delivered and barrowed down from the street last spring.
Here were the beds in spring:
And the ones now filled with summer veg in their spring virgin state:
I covered the paths between the beds with cardboard, then pine bark mulch, which has stood up well so far to constant watering and walking with very few weeds breaking through.
One of the reasons for gardening in this way is that the soil structure remains intact, the bugs, worms and soil biome are not disturbed, and the vast webs of mycelium strands that naturally form vast colonies under the soil are allowed to do their thing. Scientists are just now discovering how important this web of fungi actually is for soil and planet health, from breaking down nutrients to make them available for plants to absorb, to underground carbon capture. Something I have noticed this summer, is that though it has been incredibly dry, still there are diverse colonies of fungi popping up all over the place, where I haven't noticed it before.
So I am quite pleased with the results of my first no-dig forest gardening experiment, and hoping to refine it and improve on it as time goes on. Do let me know if you have experimented with this type of gardening technique. I'd love to know more:)

I watered in seaweed fertilisers and water-retaining soil conditioner; put down newspaper; covered over with sugar cane mulch which I let rot down. Several months later (actually probably a year and I haven’t finished the whole bed) I put in some plants with a bit of extra bought soil when I planted them.
I’d love raised garden beds so I could have a veggie plot in a no dig bed.
Cheers,

To be honest though I have no garden at the moment, too many wallabies, rabbits, possums and parrots. sigh Maybe after summer when things aren't so parched and the water tank has refilled I will try again to fence off and establish a tiny veg patch. That's all I want a tiny patch to grow just a few plants
cheers Kate
Little raised beds for vegies are great, although the less raised they are, the better they retain moisture. One sleeper high is ideal - a little bit of space to add compost and manure and mulch, but the plants basically grow in your own soil, which will become fabulously rich and full of worms when covered with compost:)
Patricia, container gardening can be very tricky. You can water every day and then suddenly discover that the water is only penetrating an inch into the soil and all the rest of the water is running down the edge and out of the bottom of the container. This sounds like what happened in your case, generally when it is very hot. Happened to me a few weeks ago, which caused a day of panicking, because the containers hold very expensive mini fruit trees! Will do a post soon on saving container plants:)
Kate, yay, tiny gardens! They are the best, because manageable! It will be lovely:)
I realised the other day I haven’t done a garden post, I feel one coming on.
I also make as much of my own compost as possible ( the chickens are useful) but I do occasionally splash out on mushroom or general compost in bulk too. I don’t buy make up, clothes or shoes so it’s my one weakness. Well, apart from books...
Will look up those other blogs, ta. And yes, a delivery of compost, now there's a fun way way to spend money:)
I notice Charles just uses compost, as it seems to be quite chilly where he is, but I think I am going to need another sheet mulch on top to get me through the rest of summer. Do you use extra mulch on top of your compost?
I also watch a lot of Geoff Lawton's videos which are helpful for drier climates..
Good soil make us gardeners look like we know what we are doing! ;-)
I was really impressed when you moved those three cubic metres that day, and the results now speak for themselves. Nice one.
If you want to go really full on no dig, when your corn is done, you can just chop the stalks at ground level. I chip up the stalks with an electric chipper chopper and then spread that back over the soil. But leaving the root systems in the ground gives the little soil critters even more food.
I do find that I have to occasionally re-apply woody mulches. After a year or so, it forms a fine black sandy loam, and most things will grow in it. The mix of soil additives would be like plant heaven for the plants! I added a bit of blood and bone to the corn patch this year too, and that seemed of benefit.
Hey do you grow brown onions? If you do, what is the best time for getting the seeds in the ground? Or do you recommend seedlings for brown onions?

Chris, confession: I have never planted or grown onions. I believe all the sorts have different planting times though, as they mature at different times.
A friend has horses so I can sometimes get some free composted manure from her which helps. The neighbours are used to seeing me barrow random things through the village, I don’t even raise an eyebrow anymore :-D
I am loving the visual of you wheeling manure through the streets. Isn't it fabulous to be old enough not to care any more?
Thanks for the reply - and I have no idea either. Not a bad place from which to commence an endeavour! :-)
Like the new format for the blog too.
Chris
PS Did you know it is legal in Tasmania to collect 100kg of seaweed per day, per person? I double checked on the DPIPWE website. This is also a great free mulch for the garden.
Chris, as you say, all the information we gather from here will be sending us upwards on the learning curve! My small garden and the ridiculous cheapness of onions has always prevented me experimenting, but I shall watch your progress with interest:)
