Troubleshooting
Geranium sanguineum 'Max Frei' problems — and how to fix them
Geranium sanguineum 'Max Frei' (Geranium sanguineum 'Max Frei') 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 in heat
White coating appears during hot, dry or congested conditions. Increase airflow, water at the base, and shear affected growth.
Crown rot in heavy wet soil
Waterlogging causes yellowing and collapse of the dense crown. Plant in sharply drained soil and avoid overwatering.
Loss of compactness
Rich soil, shade or over-feeding makes the tidy mound flop. Reduce feeding, give full sun, and shear after the first flush.
Mid-season decline
Flowering and foliage can flag in late summer. A shear-back by one-third renews the mound and triggers fresh blooms.
