When we purchased our home, it had been vacant for several years and the property was overgrown with, among lots of other weeds (and a few neat surprises), wild plum trees of all sizes. We've cleared everything and have managed to keep it clear except those darn plum trees!! They continue to pop up everywhere. We've used Tordon Brush Killer (both painted on each tree (whew!) and sprayed at the root/stump level. Any other ideas? Maybe something that can be spread over the entire lawn?

i had them when i lived in florida, and the only thing we could do was keep mowing over them. and weed wacking them, and cutting them, and and and, you get the drift. i never did get rid of them and those spikes on them were lethal!
