Question: I have a native pecan that is probably 20 years old. Is there any way to graft a better variety onto it? How is that done?
Answer: It certainly can be done, although it may involve some very serious and (initially) disfiguring pruning. You can find information on “topworking” established pecans online at the Texas A&M Horticulture Department website. It’s more and more difficult to find people who are skilled at this top-working, but your local Extension office may be able to recommend two or three local people who can do the work for you for a reasonable price.
