DeRee Tree Farm has some of the best quality trees in the Wichita area. They space their trees so that they are not narrow like the ones you buy at many nurseries and bargain shops. They are also healthy and robust.
The only other "true growers" in the Wichita area are Brady Nursery and Hillside. For landscapers and developers, you should check out DeRee TREE FARM! Their trees are at the back of their property one half mile and hidden by the large trees bordering the creek on their farm.
