cherry tree - shallow roots
My backyard cherry tree hasn't born fruit in 3 seasons, and I think I may know why. We recently discovered that the root system is extremely shallow on the tree; rather than deep roots, they are growing out wide and on the soil surface.
I'm guessing this is not a good thing. One explanation is that or soil is very clayey (we are in Sacramento), so perhaps the roots are having trouble penetrating. We recently cut some of the far reaching roots back, but we'd like to encourage the roots to go deep. Any ideas?
