Troubleshooting
Autumn heath problems — and how to fix them
Autumn heath (Erica manipuliflora) 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.
Frost damage in cold winters
Rated H3, this species can be damaged by temperatures below -5°C, especially when combined with wet conditions. Grow in a sheltered, well-drained spot; protect with fleece or move container-grown plants under cover during hard frosts. Most plants recover if only the tips are frosted.
Root rot in heavy or waterlogged soil
Though drought-tolerant, Erica manipuliflora is very susceptible to standing water. In UK winters with persistent rainfall, ensure planting sites drain freely. Raised beds or gritty mounds are recommended on heavier soils.
Reduced flowering in shade or cool summers
Flowering is dependent on adequate summer sun and warmth. In cool, cloudy UK summers or shaded positions, bloom may be sparse. Choose the sunniest available spot and consider south-facing slopes or gravel beds that reflect heat.
