Do you have specific recommendations for removing a large infestation of Japanese Angelica Tree? I have been using a 3% solution of Triclopyr with fair results, but am unsure whether the roots will generate more growth. I have been cutting larger specimens that are simply too tall to spray since they are mixed in with surrounding foliage. I plan on addressing new growth from those stumps as it appears.

The safest and most effective way to ensure no regrowth is to cut them at teh base and Immediately spray or swab round up on the remaining stump at the label rate for the concentration that you purchase.
