Watch out for

Grey mould (Botrytis): Improve air circulation around plants and remove affected material to reduce humidity.

Leaf spot: Remove infected leaves and avoid overhead watering to keep foliage dry.

Swift moth caterpillar: Hand-pick caterpillars if numbers are low; severe infestations may require biological controls.

Root rot: Ensure soil is moist but well-drained and avoid planting in heavy, water-logging clay.

Slugs and snails: Use physical barriers like copper tape or apply slug pellets sparingly around new growth.
