Geranium sanguineum 'Album' problems — and how to fix them
Geranium sanguineum 'Album' (Geranium sanguineum 'Album') 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.
Powdery mildew
White powdery film in hot, dry or crowded conditions. Improve spacing and airflow, water at the base, and shear back affected growth.
Crown and root rot in wet soil
Yellowing, collapse and a soft crown follow waterlogging. Plant only in sharply drained soil and never overwater.
Lax, sparse flowering in shade
Too little sun produces a sprawling, shy-flowering plant. Move to a sunnier, more open spot.
Mid-summer tiredness
After the main flush the mound can look tired. Shear the whole plant back by a third to renew foliage and prompt a second flowering.
