My 12 year old Cornus has been sending up suckers for years now under the base of the tree. The leaves of the suckers are different and grow straight up so maybe they’re coming from the original graft.I keep cutting them but more grow in their place and are spreading right out under the tree. What can I do? The tree is surrounded by gravel.
