Question From: J. Cardinal - CALIFORNIA
Q: My sweet gum tree had a limb fall off, first time for this size limb about 4-5” Diameter, here are pics of the branch where it broke loose, does this indicate the tree is diseased, there are no signs on tree?

A: I can't answer this question as I am not a professional arborist. If it were my trees I would get an onsite inspection from a trained professional. To find one in your area go to and enter your zip code. Best And Happy Yardening, Nancy
