I have 80 acres I hunt in Texas. There are a couple of things I would do before you pick which, or both locations to plant you food plot.
A. Where are they located? I would plant the first plot toward the middle of your property. This type of plot will pull deer into the middle and you will not just be hunting on the edges.
B. Do a soil test at each location = For your first plot you want it to be easy as possible and low cost. Trust me, the soil test will tell you how much fertalizer, lime, etc. you will need saving time and money. If one location comes back with a better test, I would start there.
C. Water and Sun - Find a spot that has moist soil when it rains (does not dry out fast, and gets good sun.
I started off trying to do one big plot, and when the seed you choose does not come up you can get really frustrated. Start small and see how it goes. If it works, make it bigger next year.
Call your local wildlife biologist. Tell them 2 or 3 of the Tecomate seed kits you are thinking about planting and ask them which ones they feel would work best. They will be straight with you and can give detail as to when to plant.
Hope this Helps
