Cherry tree suckers some distance from tree
My tree has suckers growing in the grass. How can I control it? I am digging them now but it is trouble, as there are more coming. It ruins the lawn as well.

Simply cutting the sucker off at the ground and painting the fresh cut with undiluted Glyphosphate (Round-up) will cause the roots to suck the herbicide into its local root system and kills the local roots, no need to dig them up. If by chance it does try to regrow, just repeat the process as the sucker roots will have been weakened.
Trees tend to put up more suckers when they are more stressed. The less stressed the tree feels, the less suckers you will have.
