That garden had my cucumbers, squash, several tomato and bell pepper plants. I also had onions in that garden, and they literally cooked in the ground.
We got quite a few tomatoes early on, but few since the heat set in this year. We got a lot of jalapeno peppers too.
My neighbor has a sprinkler / soaker system for his raised beds. He has a lot of tomatoes, okra, onions and other veggies. He has one cantaloupe plant that is loaded. Some of the cantaloupes are the size of volleyballs.
My garden has only survived because I was row watering (flooding).
Depending on the grade of the ground some of it has to be watered 3 passes in the same day. To allow it to soak in more evenly (high area vs low area).
Water most of it every 2 days. Usually pick the okra and squash and then water and leave alone for 2 days until time to pick again.
I put a drip irrigation system in for 22 of the new fruit trees. That helped, but still have to flood the basin around the trees about 1 time per month to settle the surrounding ground cracks.
