I moved to SC where we have sand down as far as I can dig. No good dirt whatsoever. It was 95 – 100 degrees for days on end with not much rain. I used 4 gallon pots (like the thin pots you get plants in ordered online) buried in the sand. I cut the bottoms out of the pots and put about a foot of compost below the pot then potting soil in the pots. I put the pots only about an inch apart in a row. I then cut ¾” pvc pipe into 5’ sections and set them on two sides of each pot so that I had a row of “stakes” on each side of the pots. I put T connectors on the top of each stake and cross pieces to make a top that I could attach a shade cloth to on top. It worked great and I had tomatoes all summer. I hope I explained this well enough.
Never thought I would learn to hate trees! Trees, concrete, blacktop, weeds that grew in solid matts, root eating critters, and rats that invaded my garage in broad daylight!
For all that, one of the best gardens I've grown was in the heat and sand of El Paso, TX !!! Fun stuff, huh!?!
