Do a soil sample. We need to know what type of soil you have and the nutrient levels in the soil.
How far down does the top soil go?
How much rainfall do you get per year?
How much rainfall in the summer?
What is planted in the area?
Do you have equipment?
Are you in North, Central or Southern Texas? It makes a difference.
If your rainfall is good only in portions of the year you may have to do annual plantings. Perennial plantings require an even rainfall through out the year or they will be spotty or even die in a drought situation.
