Common Pests
1. Aphids: Aphids are small insects that feed on the plant's sap, causing stunted growth and distortion of the leaves. They can be managed by spraying the plant with a mild soap solution or neem oil.
2. Spider Mites: Spider mites are tiny pests that are difficult to detect. They usually create tiny webs on the plant's leaves and suck the sap out of them. They can be managed by spraying the plant with a strong jet of water or a mix of neem oil and water.
