Troubleshooting
Many-flowered Heath problems — and how to fix them
Many-flowered Heath (Erica multiflora) 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 and waterlogging
The greatest threat in UK gardens; this Mediterranean species needs impeccable drainage and will develop Phytophthora root rot rapidly in heavy or poorly drained soils. Plant on a south-facing slope, raised bed, or gritty border. Never plant in low spots that hold winter water.
Frost and cold wind damage
Hardy to approximately -5°C but can suffer severe shoot dieback or be killed outright in hard winters in northern Britain. Site against a warm wall, apply a thick dry mulch around the base in autumn, and avoid sites exposed to cold north-easterly winds.
