Wood Avens problems — and how to fix them
Wood Avens (Geum urbanum) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Prolific self-seeding
Hooked bur seeds spread prolifically and seedlings appear throughout shaded borders; deadhead before seed sets or weed out unwanted seedlings while small.
Powdery mildew
Leaves develop powdery mildew in dry summers, especially in positions with poor air circulation; cut affected foliage back hard to encourage clean regrowth.
