Question From: N. Balon - Portland, Oregon, United States
Q: 1 of our Katsura Japonica trees is dying. It was OK until now. The leaves are desiccated, there seem to be gnaw marks at base and on south face there are bore marks in the cedar bark. We think it's the insects. Any way to reverse this?
Norb, I recommend you have an on-site inspection from a trained tree doctor, a certified arborist. They will be able to access the damage and give you an accessment of what's going on and what can be done to help. Arborist have access to products and proceedures that homeowners do not. Good Luck with your tree. Best And Happy Yardening, Nancy.
