Q.Why Is My Cherry Tree Trunk Splitting?
Please see the images of my cherry tree. The trunk is splitting and I’d love to find out why so I can try to treat it as soon as possible. Is this an insect (e.g., termites) or worm problem or something else? I’m located in Southern California (for an idea of the climate). What solutions would you suggest? Thanks for your help.
