Why is gum oozing from the bark of my cherry tree?


Our Advice:

This is bacterial canker which can kill the tree if not dealt with. Prune out dead or dying branches then treat stem cankers (areas around the gum) by painting with a paste made from Copper Mixture from Vitax. If possible, spray the tree later with Copper Mixture when the leaves are half open.
