How to Grow Weigela
Weigela
Plant weigela in full sun for the best flowers and foliage colour, in any reasonable garden soil. Prune immediately after flowering in early summer by cutting back flowered shoots to strong new growth and removing one in three of the oldest stems at the base. It is fully hardy, reliable, and loved by bees. Purple-leaved varieties need good light to maintain their colour.

☀️ Light
Full sun for best flowers and foliage colour
Full sun to partial shade. Flowers best in full sun. Purple-leaved varieties need good light to maintain their foliage colour.
💧 Watering
Regular when young; tolerant once established
Water regularly during the first year. Established plants are fairly drought-tolerant but benefit from watering in prolonged dry spells during flowering.
🌱 Fertilizing
Compost mulch after pruning; rarely needs more
Mulch with compost after pruning in early summer. Rarely needs additional feeding on reasonable soil.
✂️ Pruning
After flowering; remove oldest stems yearly
Prune immediately after flowering in early summer. Cut back flowered shoots to strong new growth and remove one in three of the oldest stems at the base each year.
Growing Tips
Prune right after flowering
Prune immediately after flowering in early summer. Cut back flowered shoots to strong new growth and remove the oldest stems at the base to keep the shrub vigorous.

Generally pest-free
Weigela is generally trouble-free. Capsid bugs may cause ragged leaf holes but plants recover well — tolerate minor damage and encourage ground beetles.
Pests & Diseases
Pest Capsid Bug
Identification: Ragged holes in leaves and distorted shoot tips; the small green bugs are rarely seen as they drop when disturbed
- Tolerate minor damage as plants recover well
- Encourage natural predators such as ground beetles
- Spray with deltamethrin or lambda-cyhalothrin if damage is severe
Pest Leaf-eating Caterpillars
Identification: Irregular holes in leaves, visible caterpillars or frass on foliage
- Hand-pick caterpillars when seen
- Encourage birds and parasitic wasps
- Spray with pyrethrin-based insecticide for heavy infestations
Pest Aphids
Identification: Clusters of small green or black insects on shoot tips and flower buds, sticky honeydew
- Squash by hand or blast off with water
- Encourage ladybirds and hoverflies
- Spray with fatty acid or plant oil-based insecticide
Disease Leaf Spot
Symptoms: Brown or purple spots on leaves, sometimes with a yellow halo, leading to premature leaf drop
Treatment: Remove and destroy badly affected leaves. Improve air circulation by thinning crowded growth
Prevention: Avoid overhead watering. Clear fallen leaves in autumn
Disease Honey Fungus Armillaria mellea
Symptoms: Sudden dieback of branches or whole plant, white fungal mycelium under bark at base, honey-coloured toadstools in autumn
Treatment: Remove and destroy infected plants including roots
Prevention: Avoid planting in sites with known honey fungus history
