Will Volck Oil Harm Juniper Bonsai

Question From: G. Castagnola - CALIFORNIA
Q: Will Volk oil harm juniper bonsai if applied other than during the winter, or at all?

A:

Your juniper may be sensitive to Volck oil. I would get the advice of a bonsai expert before using it. Google the National Bonsai Foundation for contact information. There is probably and club in your area. Best And Happy Yardening, Nancy.
