Suckers From a Crabapple Tree

Anonymous added on June 15, 2011 | Answered

I cut down a flowering crabapple tree last year, and this year I have suckers showing up all over my lawn. What can I do to stop this? From what I can find out, Sucker Stopper RTU is not available in Ontario, Canada where I live.

Undiluted Round-Up will help kill the roots. You will need to wound the roots (normally, people cut the suckers down and use those wounds) and then paint the undiluted Round-Up on the wounds. The bigger or more wounds you paint, the better. The roots will suck the Round-Up in and it will kill them. You may have to repeat the process a few times to fully kill the roots if the root system is still strong.
