I made two of these about 3 years ago, I dug into the clay soil about 3 ft down in a 5x5ft square for each bed.. Then piled everything until the mounds were about 3 feet above the soil. 3 years later or so, they're level with the rest of the original clay that hasnt been dug down, they're also the softest spot to walk in the yard, like you sink a good inch and itll fluff right back up like a sponge... I didnt even make it this good according to the picture, I literally filled the bottom with rocks to have a layer of drainage between the clay and the beds to prevent wicking or anything, and then just piled on layers of sticks, compost, leaves, twigs, logs, etc. then covered with a healthy dose of EWC and compost then topped it all off with some top soil from the original hole.. covered to prevent the sun from drying out, then once it had been seeded and covered with grass naturally I had grown tomatoes in there by the second year, turned out great, no watering no feeding, great pest and disease defense. Then this year I was trying to kill an indoor plant by putting it outside early this year as a sort of "canary in the coal mine" test and the plant actually thrived, its got some delicious looking nugs starting to flower on her now, and although the plant is tiny and had some damage from a separate incident of me trying to put the cage/wire fence trellis on and snapping the main stalk in half... But she recovered and is back in the swing of things now..
Point is... theres a natural cycle of decomposition, and those sticks and leaves and any other organic matter took energy and nutrients to grow, which will be returned to the soil naturally... You definitely can grow this plant with nothing in the sense of buying nutrients and having to go feed them... it did evolve for thousands of years without our intervention, and still grows naturally to this day, (along with everything else in the woods that grows like crazy with zero human input/farming/intervention/etc.)
If you're playing the long game, this is a great way to build up a ton of great soil using "shitty" starting materials if you have a couple years to wait..
Now I doubt OP has done anything but scooped some dirt from the backyard into that pot, but still... point stands, there are ways to grow in "rocks and sticks" that are on par or better than any man made nutrient line.
Cheers
