I'm an old-school guerrilla hole grower from way back, getting back into it after a long hiatus. I just had surgery that requires me to take it easy, so I'm scaled back, doing just a few holes and using fem seeds even. I have been digging and amending holes, and will start some beans soon. My soil is sandy loam, well drained and a bit acidic. I'm using EWC, mushroom compost, bone and blood meal, kelp meal, bat and seabird guanos, dolomitic lime, epsom salts, azomite, and Espoma Plant-tone and bio-tone, with a handful of water keep at the bottom of the hole. Holes are about 3 ft diameter and 2 feet deep, with more ferts toward the bottom. The plants should be huge, with mostly just watering required.

After mixing and filling the hole back up, I mark it with sticks and leave it for at least a month to cook. I'll come back after that to plant seedlings.

Good luck to everyone.
