St Dabeoc's heath problems — and how to fix them
St Dabeoc's heath (Daboecia cantabrica) 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
The most serious threat. Caused by waterlogged, poorly draining soil. Affected plants wilt suddenly and die from the base. Improve drainage; do not replant heathers in the same spot.
Leggy, open growth
Without annual clipping after flowering the plant becomes woody and bare at the centre. Trim lightly back into green wood each spring (April) — never cut back to bare wood or the plant will not regenerate.
Frost scorch on new growth
Late spring frosts can damage emerging shoots and flower buds. Protect with fleece in frost pockets. Choose sheltered positions in USDA zone 6.
