I have many large poplar trees growing, which is fine; however, the small shoots are spouting up everywhere. I cannot contain them. I know they shoot off suckers but my garden is being taken over and I don't know what to do! The shoots under ground are very strong and difficult to pull out, not to mention ruining the dirt around my other plants. Please help!

I have heard that there is an injection that you can do to some trees to keep them from reproducing-maybe this will work for you too.
