Slugs and snails: Use beer traps, copper tape barriers, or hand-pick at night to protect emerging seedlings.
Powdery mildew: Improve air circulation by thinning dense growth and avoid overhead watering to keep foliage dry.
Root rot: Ensure well-drained soil by incorporating grit or planting on a raised bed if drainage is poor.
Vine weevil: Apply nematodes to the soil in late summer or use biological controls like Steinernema carpocapsae.
Nutrient deficiency: Apply a balanced, slow-release organic fertilizer in spring if growth is stunted or discoloured.
