Root rot: Ensure sharp drainage by planting in gritty compost or well-drained gravelly soil.
Slugs and snails: Use physical barriers like copper tape or apply iron phosphate pellets around the base.
Vine weevil: Apply nematodes to the soil in autumn or use systemic insecticides for potted specimens.
Powdery mildew: Improve air circulation and spray with a sulphur-based fungicide if infection is severe.
Sap irritation: Wear gloves when planting or dividing and wash hands thoroughly afterwards.
