Watch out for

Slugs and snails: Use physical barriers like copper tape or apply iron phosphate pellets around the base.

Grey mould (Botrytis): Improve air circulation and remove affected plant parts to reduce humidity around the foliage.

Root rot: Ensure soil is moist but well-drained and avoid overwatering, especially in winter.

Vine weevil: Apply biological nematodes to the soil in late summer or autumn to control larvae.

Powdery mildew: Spray with a fungicide or milk solution and ensure good air circulation around plants.
