Growth Stages

Flowering ~90d

Approximate days from start

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

Organic treatment:
  • Blast off with a strong jet of water
  • Spray with fatty acid-based insecticide
  • Encourage ladybirds, lacewings and hoverflies
Chemical treatment:
  • 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

Organic treatment:
  • Use beer traps or copper tape barriers
  • Apply organic slug pellets (ferric phosphate)
  • Encourage natural predators such as hedgehogs and ground beetles
Chemical treatment:
  • Ferric phosphate-based pellets
Pest Caterpillars

Identification: Irregular holes or ragged edges on leaves, caterpillars visible on or under foliage

Organic treatment:
  • Pick off by hand
  • Apply Bacillus thuringiensis (Bt) biological spray
Chemical treatment:
  • 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
