Dianthus gratianopolitanus 'Firewitch' problems — and how to fix them
Dianthus gratianopolitanus 'Firewitch' (Dianthus gratianopolitanus 'Firewitch') 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 rot in wet soil
The leading cause of failure — poor drainage or winter wet rots the dense crown. Plant in gritty, free-draining soil and surround the crown with grit.
Loss of reblooming without deadheading
Removing spent flowers promptly encourages a second flush; left unsheared, the display ends earlier.
Centre die-back with age
Older cushions can hollow out in the middle; shear lightly after flowering and take cuttings to renew the planting.
Rust on humid sites
Damp, crowded, or overhead-watered plants may develop rust pustules; water at the base and ensure airflow.
