Ask Dr. G

Dr. Greg Church (or Dr. G) is a highly knowledgeable and experienced plant pathologist who is willing to answer tree-related questions. Please provide as much information as possible, as well as a number of photos of the problem from various angles and distances. If Dr. G is unavailable, one of our other plant pathologists, certified consulting arborists, foresters, or horticulturalists will respond on his behalf.

Because our experience is focused in North Central Texas, we are only able to respond to questions within this area. Thank you.
