What's eating my ranunculus asiaticus 'cloni success arancio'?

Persian ranunculus 'Cloni Success Arancio' is most commonly attacked by aphids, which colonise buds and soft stems. Powdery mildew and botrytis thrive in cool damp conditions, while slugs target tender growth. Managing moisture and acting quickly on aphid colonies keeps this cultivar healthy.

Dense colonies on flower buds and young stems; sticky honeydew leads to sooty mould and distorted blooms. Knock off with a firm water jet. Apply insecticidal soap or neem oil spray, repeating weekly. Introduce aphid predators such as lacewings where possible.

Ragged holes in emerging leaves and stems, with characteristic slime trails. Use iron phosphate pellets around corms at planting. Set beer traps or go out at night to hand-pick. Avoid overwatering which attracts slugs.

Fine silvery streaks or speckling on petals; flowers may brown at edges prematurely. Remove badly affected blooms. Spray with spinosad or insecticidal soap in the evening. Keep foliage dry where possible.
