How to Grow Peony
Paeonia
Peonies are long-lived perennials that can thrive for decades in full sun to light shade with fertile, well-drained soil. The most important rule is planting depth — set the eyes no more than 2.5cm below the soil surface. Feed with bone meal in spring, support heavy blooms with peony rings, and cut herbaceous types to ground level in autumn. Be patient; peonies can take two to three years to flower after planting but reward you for a lifetime.
Yearly Lifecycle
Care Essentials
Spring with bone meal or a balanced fertiliser as shoots emerge. Mulch with compost (not over the crown).
Watch For
- Peony wilt (botrytis)
- Honey fungus
- Leaf blotch
Companions
Roses, Iris, Geraniums, Alliums

☀️ Light
Full sun to light shade; best flowering in sun
Full sun to light shade. Peonies flower best in full sun but appreciate light afternoon shade in hot positions. Avoid deep shade.
💧 Watering
Water in dry spells; avoid overhead watering
Water during dry spells, especially in the first two years after planting. Established peonies are fairly drought-tolerant. Avoid overhead watering.
🌱 Fertilizing
Bone meal in spring; mulch away from crown
Apply bone meal or a balanced fertiliser in spring as shoots emerge. Mulch with compost but keep it away from the crown to prevent rot.
✂️ Pruning
Cut herbaceous types to ground in autumn
Cut herbaceous peonies to ground level in autumn after foliage dies back. Tree peonies need minimal pruning — remove dead wood only.
🌿 Support
Support rings early; heavy blooms need staking
Install peony support rings in early spring before growth gets tall. Heavy double blooms will flop without support, especially after rain.
Growing Tips
Planting depth is key
Plant with eyes no more than 2.5cm below the soil surface; too deep and peonies will not flower.
Support early
Install peony support rings in early spring before growth gets tall; heavy double blooms flop without support.
Act fast on wilt
Watch for peony wilt (botrytis) in cool, damp springs; cut out affected stems below ground and destroy.
Autumn clean-up
Cut herbaceous peonies to ground level in autumn and clear all debris to reduce disease carry-over.
Pests & Diseases
Pest Peony Scale
Identification: Small white or brown oval bumps clustered on stems, especially near the base. Weakened growth in severe cases.
- Scrub off scale with a soft brush in winter
- Apply a winter plant oil wash to smother overwintering scale
- Spray with a plant oil-based insecticide in the dormant season
Pest Slugs and Snails
Identification: Irregular holes chewed in young shoots and developing buds. Slime trails visible around the crown.
- Apply organic slug pellets (ferric phosphate) around emerging shoots
- Use copper tape barriers
- Encourage hedgehogs, frogs, and ground beetles
- Ferric phosphate pellets (approved for organic use)
Disease Peony Wilt (Botrytis) Botrytis paeoniae
Symptoms: Stems wilt and collapse at the base, turning brown. Grey fuzzy mould may appear on affected tissue in damp weather.
Treatment: Cut out affected stems to below ground level and destroy. Do not compost.
Prevention: Ensure good air circulation. Avoid overhead watering. Remove dead foliage in autumn.
Disease Peony Leaf Blotch Cladosporium paeoniae
Symptoms: Purple-brown blotches on leaves, spreading and merging. Leaves may wither prematurely in severe cases.
Treatment: Remove and destroy affected foliage. Cut all stems to ground level in autumn and clear debris.
Prevention: Clear all old foliage in autumn. Mulch in spring to prevent soil splash. Avoid overcrowding.
Disease Honey Fungus Armillaria mellea
Symptoms: Sudden wilting and death of the whole plant. White fungal sheets under the bark at the base. Honey-coloured toadstools in autumn.
Treatment: Dig up and destroy affected plants including all roots. Replace soil before replanting.
Prevention: Maintain plant vigour. There is no chemical prevention. Physical barriers (buried plastic sheeting) can slow spread.
