Care Essentials
- Apply a balanced liquid feed every two weeks once shoots emerge. Avoid high-nitrogen feeds that promote leafy growth at the expense of flowers.
- De Caen types produce single poppy-like flowers; St Brigid types have semi-double or double blooms. Both are superb cut flowers. Succession planting every 3–4 weeks extends the season considerably.

Pests & Diseases
Pest Aphids
Identification: Clusters of small soft-bodied insects on shoot tips and flower buds, causing distorted growth and sticky honeydew
- Blast off with a strong jet of water
- Spray with fatty acid-based insecticide
- Encourage ladybirds, lacewings and hoverflies
- Spray with a contact insecticide containing deltamethrin or lambda-cyhalothrin
Pest Slugs and Snails
Identification: Irregular holes in young leaves and slime trails around plants, worst in wet weather
- Use beer traps or copper tape barriers
- Apply organic slug pellets (ferric phosphate)
- Encourage natural predators such as hedgehogs and ground beetles
- Ferric phosphate-based pellets
Pest Caterpillars
Identification: Irregular holes or ragged edges on leaves, caterpillars visible on or under foliage
- Pick off by hand
- Apply Bacillus thuringiensis (Bt) biological spray
- Spray with a contact insecticide if infestation is severe
Disease Grey Mould (Botrytis)
Symptoms: Grey fuzzy mould on stems, leaves, and flowers, causing collapse of affected tissue
Treatment: Remove and destroy affected parts immediately. Improve air circulation. Apply a fungicide containing tebuconazole if severe
Prevention: Space plants well, avoid overhead watering, remove dead plant material promptly
Disease Powdery Mildew
Symptoms: White powdery coating on leaves and stems, causing yellowing and reduced vigour
Treatment: Remove badly affected leaves. Spray with a fungicide if severe
Prevention: Space plants well for good airflow, avoid water stress, and water at the base
Disease Corm Rot
Symptoms: Corms become soft, discoloured, and fail to produce shoots; plants collapse at the base
Treatment: Remove and destroy affected corms. Do not replant in the same spot
Prevention: Ensure excellent drainage before planting. Never plant in waterlogged soil. Soak corms in a fungicide solution before planting if rot has been a problem
