Ailanthus Trees- Killing Sprouts

Q: I cut down the largest of several ailanthus tree saplings next to my fence. I ended up with fifty sprouts in its place. How do I kill these things without getting a hundred more saplings?

A: Cut each sapling as close to the ground as you can. Spray glyphosate (Roundup, etc) onto the stump. No sprouts will occur near on or adjacent to the stump. A few sprouts from nearby roots may occur but you can easily treat them the same way.
