Troubleshooting
Corsican Heath problems — and how to fix them
Corsican Heath (Erica terminalis) 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.
Phytophthora root rot
The primary threat, especially in heavier UK soils or wetter climates; affected plants wilt and die rapidly. Plant exclusively in sharp-draining soil, incorporate coarse grit on heavier ground, and avoid irrigating when rainfall is already adequate.
Frost dieback
Stems can be killed back in winters colder than -10°C or in exposed sites that trap frost. In colder UK gardens (USDA 7), grow against a sheltered south-facing wall; cut back frost-damaged stems to healthy growth in late spring once new buds are visible.
