What are good shade trees for central Texas and how far apart should they be planted?

Do you want trees that produce fruit or nuts? Or seed pods? Or ones whose leaves turn pretty colors in autumn?

What trees can I grow in my back yard for shade in Central Texas? And how far apart must they be planted?

Any of the above would be fine, thank you

Pecans!

''Central Texas'' is a big area and a lot depends on your soil. Before you spend any money, check with your nearest state ag station. They will test your soil and give you all the advice you need for your area. Also visit local garden centers without buying anything at first. You need to be concerned with local rainfall stats as well as soil type.

How far apart will depend on the tree species. Allow at least 20' between even the shortest ones.
