|I have an ornamental purple leaf plum tree in a large mixed border that sends out suckers 10-15 ft. from the tree trunk. I try to pull them but they're too deep. I've been cutting them off but they grow back very quickly. Do I have any recourse other than removing the tree? It is very pretty with spring bulbs & perennials.

|Ornamental purple leaf plums have a tendency to sucker. You can cut them back and then spray with Sucker Stopper RTU. (Mfg. by Monterey Lawn & Garden Products) It is a plant growth regulator and will stop the suckering.
