Watch out for

Slugs and snails: Use physical barriers like copper tape or beer traps, and hand-pick at night.

Vine weevil: Check roots when planting and apply biological nematodes in warm, moist soil.

Powdery mildew: Ensure good air circulation and avoid overhead watering to keep foliage dry.

Root rot: Plant in well-drained soil and avoid overwatering, especially in heavy clay.
