Entretien

Plant in acidic soil and keep it consistently moist but never waterlogged. Prune back the old flower spikes after they fade to encourage a tidy shape and fresh growth. Watch for yellowing leaves, which often signals that the soil pH is too high.

Watering

Keep the soil consistently moist but ensure it drains well to prevent root rot.

Feeding

Apply a slow release acidic fertilizer in early spring.

People

This plant is generally considered non toxic to humans.

Children

The small, dense foliage may pose a minor choking hazard if ingested by very young children.

Contact allergens

The foliage can cause mild skin irritation in sensitive individuals due to fine hairs.

Airborne allergens

The pollen is not considered a significant allergen for most people.

Edibility

While heather is sometimes used in traditional teas, it is not considered a food crop and should be consumed with caution.

Propagation

cuttings, division, seed

When to plant

spring, autumn

Overwintering

In cold climates, apply a light mulch around the base to protect roots from freezing and thawing cycles. Keep the plant in a spot with good air circulation to prevent fungal issues during wet winter months.

In containers

It grows well in containers if you use a large pot with excellent drainage and acidic potting mix.

Group plants with similar acidic soil needs to ensure everyone stays healthy.

Bonnes associations

• Erica — They share similar soil and light requirements for a cohesive look.
• Blueberry — Both plants thrive in the acidic soil conditions that heather prefers.

À éloigner de

• Lavender — Lavender prefers alkaline soil, which will eventually kill the heather.

Espèces similaires

• Winter Heath — It looks very similar but blooms in late winter or early spring.

Science

Family

Ericaceae

Genus

Calluna

Order

Ericales

Class

Magnoliopsida

Native range

Europe and parts of Asia Minor.

Conservation

It is not currently threatened, but wild harvesting should be done sustainably to protect local heathland habitats.

It dominates nutrient poor, acidic heathlands by forming dense mats that suppress competing vegetation.

Value to wildlife

nectar source, winter cover

Pollinators

bees, butterflies

Uses

groundcover, rock gardens, pollinator gardens

Ce qu'on demande souvent

Does it need acidic soil?

Yes, it thrives in acidic, well draining soil.

How often should I prune it?

Prune lightly after flowering to keep the plant compact.
