Troubleshooting
Strawberry Foxglove problems — and how to fix them
Strawberry Foxglove (Digitalis × mertonensis) 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
Heavy, waterlogged winter soil rots the perennial crown. Plant in free-draining, humus-rich ground and avoid winter wet.
Powdery mildew
The broad leaves can develop mildew in crowded, humid sites. Space clumps and improve ventilation.
Declining vigour over time
Clumps gradually weaken after a few years. Lift and divide every 2-3 years in spring or autumn to rejuvenate.
Leaf scorch in dry sun
Foliage browns at the edges in hot, dry exposure. Site in part shade and keep the root zone moist and mulched.
