Troubleshooting
Geranium 'Orion' problems — and how to fix them
Geranium 'Orion' (Geranium 'Orion') 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.
Spreads vigorously
Its strength as ground cover can mean it crowds smaller neighbours. Plant where it has room, or lift and divide to keep it within bounds.
Mid-season flop and tatty foliage
After the first big flush, growth can look untidy. A hard shear back to the base rejuvenates fresh leaves and triggers further flowering.
Powdery mildew
Dry soil plus crowded foliage can bring white mildew. Keep roots moist, water at the base, and improve airflow between plants.
Vine weevil
Larvae may damage roots, especially in containers, causing sudden wilting. Inspect roots and apply nematode controls in late summer if grubs are present.
