Hugelkultur in pots?

I live in a condo and have only about 8sq ft (2'x4') of soil i can plant in. So the base of my gardening is with pots. I tried for the first time this summer a tomato plant in pot and it dries out so fast. It did ok but i know i can do much better.

So i had an idea inspired of hugelkultur.

Did some of you ever tried adding soaked and rotting wood at the bottom of pots to help maintain humidity for roots? Having pebbles at the bottom to avoid stagnant water and root roting.
Fyi most of my pots are plastics not clay so there is no evaporation from sides.

Any tought?

I want to have tomatoes in pots only for next year to rotate crops in my "field". 😆

I'm testing in a couple of very large pots and so far so good, but I didn't over do the wood in the bottom-less than a foots worth. I soaked the wood and it was dead dry stuff so I'm sure breaking down quickly in my Florida heat. Kicking around trying it on a smaller scale in a 10" pot with greens this fall. If you haven't found him yet, check out "Home Grown Veg" on you tube. He's in the UK and grows almost everything in containers. Entertaining gentleman and he's led me to try things in pots I never thought of. The plastic tend to dry out much quicker here than clay, but I do think the wood is helping in those pots.

😃 thanks! That's what i was looking for.

Funny you should post this.  A couple of months ago, I had an old water trough, a little one, that I wasn't using any more.  I had already drilled some holes in it in a failed attempt to fasten slow feed hay nets to it, so it wasn't any use as a water trough any more.  I have a bunch of woody branches lying around from tree trimming that didn't get chipped, so I chopped some up and put it in the bottom.  I filled about 8" of the 18" depth with it leaving big void spaces.  I had some Happy Frog potting soil lying around so I filled the rest of it with that, and planted a bunch of herbs... parsley, chives, sage, chinese chives, thyme, feverfew, etc.  I soaked the heck out of it, then ignored it for a couple of weeks.  It held the moisture remarkably well, a lot better than the hugelkultur beds I was experimenting with.   The herbs are real happy.  I have to admit though, I haven't put in full sun yet because I had just transplanted, but I plan to drag it out where it gets sun most of the day soon.  I did not presoak the wood and it turned out fine.  I won't hesistate to do this again... it saves on soil quantities used, helps with root aeration and holds moisture!

are you growing inside? on a deck? small section of yard?

On a deck in summer and inside for winter.
