Geranium cinereum 'Ballerina' problems — and how to fix them

Geranium cinereum 'Ballerina' (Geranium cinereum 'Ballerina') 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.

Crown and root rot

The single biggest killer, caused by heavy or wet soil, especially over winter. Plant in sharp drainage, add grit around the crown, and avoid mulching directly over the rosette.

Decline in shade or rich soil

Too little sun or over-feeding makes growth loose and floppy with sparse flowers. Site in full sun and keep the soil lean and gritty.

Powdery mildew

A pale coating in humid, still conditions. Ensure open airflow and avoid overhead watering; shear lightly to refresh the rosette if affected.

Vine weevil

Grubs eat roots of trough- and pot-grown plants, causing collapse. Inspect roots when potting on and treat with nematodes if larvae are found.
