Troubleshooting
Bell heather problems — and how to fix them
Bell heather (Erica cinerea) 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.
Phytophthora root rot
Caused by waterlogged or poorly drained soil; plants wilt and die rapidly. Ensure excellent drainage and never let roots sit in standing water. No effective treatment once infected — remove and destroy affected plants.
Heather dieback (Phytophthora cinnamomi)
Patches suddenly brown and die even without waterlogging. This soilborne pathogen spreads via infected compost. Buy plants from reputable nurseries and avoid replanting heathers in the same spot.
Leggy, non-flowering growth
Caused by insufficient sun or failure to trim annually. Clip shoots lightly (not into old woody stems) immediately after flowering each year to maintain a compact mound and stimulate fresh blooming growth.
