Mr. Bowsky:

Thanks for your email. I wanted to clarify that you're asking about only lesser celandine; you mention pruning and killing fruit trees, which sounds like something taller and more vigorous than lesser celandine.

As for the lesser celandine, we're testing very low rates (2-4%) of glyphosate (the active ingredient in Roundup) this month to determine effectiveness. We've heard from other folks that digging doesn't seem to help much. Feel free to check back with me on our results via email (mitch.bixby@bes.ci.portland.or.us).

Thanks again for your questions.
-Mitch
