Jenny, I have been told that pouring vinegar (undiluted) on freshly cut stumps will keep many species from resprouting from the roots.

I'm curious to see if we have both species at NY Bot. Garden. As far as control, we're manually removing them and as much of the roots as possible. If there is any use of chemicals, I don't know about it. With the Bronx River right in the middle, the risk of polluting is too high. I know in the past there was a problem with fertilizer run-off into the river which I believe has been addressed. We shall see if the Aralia "devil" can be controlled....
