It can be caused by a variety of factors, including humidity, poor air circulation, and over-watering. To manage powdery mildew, remove and destroy infected leaves as soon as possible. Avoid watering the leaves, and ensure that the plant has adequate air circulation. Fungicidal treatments may also be necessary in severe cases.
2. Rust: Rust is a fungal disease that appears as small, yellow-orange pustules on the leaves. It can be caused by damp conditions and poor air circulation. To manage rust, remove and destroy infected leaves. Avoid overhead watering and ensure that the plant has adequate air circulation. Fungicidal treatments may also be necessary.
3. Root Rot: Root rot is a fungal disease that can be caused by over-watering or poorly-drained soil. Symptoms include wilting, yellowing leaves and stunted growth. To manage root rot, remove and destroy infected plants. Improve soil drainage by adding organic matter, and avoid over-watering.
Pests:
1. Aphids: Aphids are small, soft-bodied insects that feed on the sap of plants. They can cause stunted growth and distorted leaves. To manage aphids, wash the plant with a strong stream of water or treat with insecticidal soap. Ladybugs and other beneficial insects can also help to control aphid populations.
2. Spider Mites: Spider mites are tiny, spider-like insects that feed on the underside of leaves. They can cause yellowing leaves and webbing on the plant. To manage spider mites, wash the plant with a strong stream of water or treat with insecticidal soap. Neem oil and other organic treatments may also be effective.
3. Thrips: Thrips are small, slender insects that feed on the leaves and flowers of plants. They can cause distorted growth and a silvery appearance on the leaves.
