I would think that you would want them out sooner than that march/april

the thing with texas is you have to have water to grow anything so if you cannot irragate then you have to time your planting down according to when you can get some adequate rain. You want something that is drought tolerant, and beneficial to the deer (antler growth and healthy does for up coming fawns). All I dois feedprotein (antler max). Sometimes you can look at different web sites like biologic or the whitetail institute. They have guides that show youwhen and what toplant, or you could just drive around and see what is growing around your area see what farmers are planting and find out which are most beneficial to the wildlife. Good luck.....
