Watch out for

Bulb rot: Ensure excellent drainage in compost and allow bulbs to dry completely during their dormant period.

Powdery mildew: Improve air circulation around plants and treat with a suitable fungicide if infection is severe.

Vine weevil: Apply nematodes to the soil in autumn or use a systemic insecticide drench for prevention.

Slugs and snails: Use slug pellets, beer traps, or hand-pick pests at night to protect tender growth.

Overwatering: Water sparingly during dormancy and ensure pots have adequate drainage holes.
