Your land looks very pretty! What area of Central Texas are you in? I am about halfway between Austin and College Station, and your land looks very similar to the land around here.
My first thought is will you be living on the land? And do you have a way to protect your plantings from
deer and bunnies? And a way to protect your critters from predators like coyotes and bobcats?
It is definitely not the best time to plant most things, especially with how hot and dry it already is this year. I would probably spend the next few months planning and then plant towards the end of the summer. For most perrenials, like fruit trees, fall is the best time to plant anyway. You can plant annual vegetables in the late summer though, for a fall/ early winter harvest. And you can plant cool-season veggies like greens in the fall to use throughout the fall, and hopefully the winter and spring, if the weather isn't too crazy (80 degree days followed by a sudden freeze, and strong wind, like we had multiple times this winter, are really hard on plants).
A really great book with detailed charts on what
should be planted when in different areas is "Texas Organic Vegetable Gardening" by Howard Garrett. I bought mine used
online at Thriftbooks.com, but you also might be able to find it elsewhere. I refer to it ALL THE TIME, especially since I only moved here a year ago and nothing is really set in my mind yet.
Another thing you could be doing now, to prepare for fall, is building things like lasagna beds, so they may have composted down enough to plant into in the fall. When I clean out my goat houses I am piling the
hay,
wood chip, manure mix into rectangles, and layering in old bits of wood, dry leaves, kitchen
compost, etc to make lasagna beds, in the hopes they will be ready to plant in the fall. I know they won't be fully composted down, but I will make little "nests" in the material, add some good, ready-to-grow-in soil to the nests, and plant into those. If you are a beginner gardener, than the book "
Lasagna Gardening" by Patricia Lanza might be a good place to start. I read it recently, but since I had been
gardening for a long time and hanging out here and in
gardening forums, I found that I didn't learn anything new from it.
