Meadow Buttercup problems — and how to fix them
Meadow Buttercup (Ranunculus acris) 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.
Aggressive self-seeding
Meadow buttercup produces abundant seed and can become invasive in lawns and borders; deadhead promptly after flowering if seed spread is unwanted, or choose the sterile double cultivar 'Flore Pleno'.
Powdery mildew in dry conditions
White mildew appears on leaves during dry spells, particularly in late summer; ensure consistent soil moisture and divide overcrowded clumps to improve air flow.
