Well, have all my tomatoes and peppers planted in buckets. They soil in Az suks on the Mogollon rim. Made a raised garden with turnips, squash and some beans. Planted a row of beans, and the hot sun is drying them out even after watering twice a day.
Zucchini, squash, and cucumbers doing fine despite the cats using most of my garden as a litter box.
Planted some beets in boxes and are doing well.
The weather has been horendous. Way too hot, in the upper 90s. Waiting for the monsoons to start.
It’s supposed to cool off tomorrow.
You certainly have some challenges. Kudos on your perseverance. Here in Michigan it’s almost too humid. We have to be careful not to water too much or we have rotting tomatoes. Wonder if some shade screen over your beds would help. Just to cut down some of the sun and heat.
