Raised bumps on Apple Tree
We are trying to grow fruits and vegetables organically in our backyard and always have so much trouble with our one apple tree :(
Today I found all these raised bumps on the apple tree trunk (see image) - what are we looking at? Anyone else out there with this problem? Is this fixable?
Thank you so much for sharing your ideas.
