How many of you guys offer tree services (fertilizer/pesticides)? It seems like every call I have received this year has asked for these services. I want to try to take care of the customers' needs, but I am absolutely clueless when it comes to trees (kind of embarrassing, since I have a Masters degree in Horticulture). I am trying to get an idea about a general seasonal service plan for small trees in my area as well as finding some idea of how to price the service. I have searched the site with little luck. Anyone have advice?
