Troubleshooting
Strawberry Foxglove problems — and how to fix them
Strawberry Foxglove (Digitalis x 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.
Shorter life than expected
More perennial than D. purpurea but may only persist 3–4 years. Allow self-seeding or propagate every few years.
Crown rot
Wet winter conditions can kill the crown. Ensure excellent drainage at the planting site.
Aphid colonies
Can appear on flower spikes. Knock off with a water jet or use insecticidal soap.
Slug damage
Young growth is vulnerable in spring. Protect with barriers or slug nematodes in damp conditions.
Fading colour in poor conditions
Flower colour is best in cooler conditions with even moisture; heat stress fades the distinctive strawberry tones.
