Troubleshooting
Whorled Heath problems — and how to fix them
Whorled Heath (Erica manipuliflora) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot in wet or clay soils
This Mediterranean species is highly intolerant of waterlogged conditions; prolonged wet soil causes rapid Phytophthora root rot. Always plant in sharply drained, gritty soil and avoid low-lying frost pockets where water pools.
Frost damage in cold winters
Hardiness drops significantly below -5°C; shoot tips and stems can be killed back in hard winters in northern gardens. Site against a south-facing wall in UK zone 8 gardens, or grow in a container that can be brought under glass in severe cold.
