Dwarf Lady's Mantle problems — and how to fix them
Dwarf Lady's Mantle (Alchemilla erythropoda) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Self-seeding invasiveness
Plants set abundant seed and can self-sow prolifically. Deadhead flower stems promptly after blooming to prevent unwanted spread. Seedlings are easily hand-pulled when young.
Powdery mildew in dry spells
White powdery coating on leaves may appear in hot, dry summers, especially when plants are stressed. Cut back affected foliage to ground level; fresh growth typically emerges clean. Improve air circulation and water at the base.
Scorched or tatty summer foliage
Leaves may look ragged by midsummer, especially in sunny spots. Shear the entire plant to a few centimetres above ground level — fresh, clean foliage will regrow within weeks.
