Pray for a lot of rain.
Seriously, looking at the lake levels in my area we will not be putting in a garden or even replacing anything we lost last year in our yard. Texas is still in an extreme drought and unless we get a miracle nothing will change this summer.
I'm going to container garden for a few "fresh" things. I've given up on tomatoes. My flower beds by the house are "agri-scaped" with herbs. Ane we MULCH with newspaper, compost, leaves, etc. By the end of June we'll be lucky to have much out there (due to water rationing). I'm resourceful and use gray water to water trees, etc. by diverting the water from the washer into the yard. If I didn't live on a limestone rockbed I'd want holding tanks but my HOA frowns on TNT (I can't imagine why...) I'd ask neighbors what grows in your area. Good luck with the gardening. What do you have to lose but a few seeds and a little effort?
