Backyard apple tree branches dying at bottom
I have an apple tree which looks like it is dying from the bottom up. It produced many apples some of which are still on the tree. The top branches are full and green and looks like new growth on some of the branches. The bottom seems like most are dying. What should be done......can it be saved?
There could be canker disease affecting the tree. https://extension.umd.edu/hgic/cankers-trees-and-shrubs There is also sapsucker damage. https://extension.umd.edu/hgic/woodpeckers-and-sapsuckers The holes from the sapsucker damage can be entry points for disease and wood-decaying organisms.
There is no "cure" for these symptoms. Prune out the dead branches as best as you can. That's really all you can do.
