Geranium sanguineum var. striatum problems — and how to fix them
Geranium sanguineum var. striatum (Geranium sanguineum var. striatum) 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 film during hot, dry or crowded spells. Improve airflow, water at soil level, and shear back affected growth.
Crown rot in wet soil
Yellowing and collapse follow waterlogging. Plant only in sharply drained soil and avoid overwatering.
Sparse flowering in shade
Insufficient sun yields a loose, shy-flowering mat. Relocate to a fully sunny position.
Tired late-summer foliage
The mat can look spent after the main flush. Shear back by a third to renew leaves and prompt rebloom.
