Damping-off: Damping-off is a fungal disease that usually affects seedlings. The infected plants appear stunted and may eventually wilt and die. To prevent damping-off, ensure that the soil is well-draining and avoid overwatering.
Downy mildew: Downy mildew is a fungal disease that causes yellowing and wilting of leaves. The infected leaves may also develop white or gray powdery growth underneath. To manage downy mildew, avoid overcrowding the plant and provide adequate spacing between them to promote proper air circulation.
Common Pests
Aphids: Aphids are tiny insects that feed on plant sap and excrete a sugary substance that attracts ants. The infected plants may become stunted, and the leaves may curl or yellow. To manage aphids, prune and discard infected plant parts and use insecticidal soap or horticultural oil to control their population.
Snails and slugs: Snails and slugs are common pests that feed on the plant's foliage, leaving behind large holes. To manage snails and slugs, use physical barriers such as copper tape around the plants and baits formulated with iron phosphate.
