Borer or Other problem?
Hello - In my front yard, I have a nice 15 foot tree (not sure what kind) that is dipping sap at the base like crazy. It is particularly bad on one side and is getting worse.
I used the Bayer Advanced insect formula last fall and again in April but it seems to have had no impact.
I dont want to lose this otherwise healthy tree - what should I do - call experts to treat it? Is it definitely an insect issue?
I really appreciate your expert opinions and can post more pics if needed. Thanks! Jen
