Q.Apricot Tree Problem
I live here in Santa Cruz, CA and my apricot tree is having problems. Maybe you can help me. It seems that some of the new growth is dying off and little sap balls are starting to form. I had some brown rot last year and sprayed the tree three separate times with a product called Liqui-cop before and growth showed. Can you help? here are a couple of pictures. Any advice would be helpful.
