How to Grow Winter Heath
Erica carnea
Winter Heath (Erica carnea) is a low, spreading evergreen shrub that flowers from January to April, bringing colour to the garden when little else blooms. Unlike most heathers, it tolerates neutral to alkaline and chalky soil, so ericaceous compost is not required. Plant 30 cm apart in full sun to partial shade in well-drained soil. Trim lightly with shears after flowering, cutting back into the green growth but never into old bare wood. Erica carnea is fully hardy, drought-tolerant once established, and one of the best plants for winter ground cover and rockeries.

Care Essentials
Rarely needed. If growth is poor, apply a balanced feed in spring.
Watch For
- Phytophthora root rot in waterlogged soil
- Heather beetle
- Vine weevil in containers
- Grey mould in wet conditions
Companions
Calluna vulgaris (summer heather), Rhododendron, Pieris, Dwarf conifers
Care Requirements
Light
Full sun to partial shade
Best flowering and foliage colour in full sun. Tolerates partial shade but may flower less freely. Avoid deep shade which causes leggy growth and poor bloom.
Watering
Drought-tolerant once established; avoid waterlogging
Water newly planted Erica during dry spells in the first season. Once established, it is drought-tolerant. Waterlogged soil causes fatal Phytophthora root rot. Use rainwater where possible as tap water can raise soil pH over time.
Fertilizing
Rarely needed; balanced feed only if growth is poor
Erica carnea thrives in poor soil and rarely needs feeding. If growth is weak or foliage yellows, apply a light balanced fertiliser in spring.
Pruning
Light trim after flowering; never cut into old bare wood
Shear spent flower stems lightly in March–April after blooms fade, cutting back into the leafy green growth. This keeps plants compact and prevents them becoming woody. Never cut into old bare wood — Erica will not regrow from it.
Spacing
30 cm apart for ground cover
Plant 30 cm apart for dense ground cover that suppresses weeds. Space 40–45 cm if you want individual plants to develop. Erica carnea spreads slowly to 45 cm wide.
Growing Tips
Happy on chalky soil
Unlike most heathers, Erica carnea grows well in neutral to alkaline and chalky soil, so there is no need for ericaceous compost. What it will not tolerate is waterlogging, so choose a well-drained spot.
Trim after flowering, never into old wood
Shear spent flower stems lightly in spring after blooms fade. Cut back into the leafy green growth but never into old bare wood — Erica will not regrow from it.
Combine with summer heather for year-round colour
Pair Erica carnea (winter–spring flowers) with Calluna vulgaris (summer–autumn flowers) for heather in bloom across almost every month of the year.
