Question
Last year I had 3 locust trees removed (not the stumps) and this year I have been battlng root suckers everywhere.  What is the best way to get rid of them. I do not want to grind out the stumps because they are holding my hillside from coming down.

Thank You

Answer
Wipe the foliage of the sprouts with a herbicide called Roundup. A sponge paint brush will work well. Be aware that Roundup will kill any green plant it gets on so make sure you do not drip the Roundup on plant not wanting killed. The sprout will absorb the herbicide and transport it to the roots killing the root system and the there will be no more sprouts.
