Here are some common pests and diseases that can affect the plant and ways to manage them:
Diseases
Root Rot
Root rot is caused by a fungus that thrives in damp soil. Signs of root rot include yellowing leaves, stunted growth, and wilting. To avoid root rot, make sure the soil is well-drained and avoid overwatering the plant. If you suspect root rot, remove the affected areas and improve drainage to prevent further infection.
Leaf Spot
Leaf spot is caused by a fungus that typically appears as small, circular spots on the leaves. These spots can multiply and cause the leaves to turn brown and eventually fall off. To manage leaf spot, remove affected leaves and dispose of them properly. Provide adequate air circulation around the plant. Fungicides can also be used to manage leaf spot, but they should be applied according to the package instructions.
Powdery Mildew
Powdery mildew is a fungal disease that appears as a white, powdery substance on the leaves. It can cause leaves to yellow and eventually fall off. To manage powdery mildew, remove any affected areas and dispose of them properly. Prune part of the plant to provide adequate air circulation. Fungicides can also be used to manage powdery mildew, but they should be applied according to the package instructions.
Pests
Aphids
Aphids are small, soft-bodied insects that feed on the sap of plants, causing leaves to curl and turn yellow. To manage aphids, spray the plant with a strong stream of water to knock them off, or introduce natural predators such as ladybugs. Insecticidal soap or neem oil can also be used to manage aphids, but they should be applied according to the package instructions.
Spider Mites
Spider mites are tiny insects that can create webbing on the plant. They feed on the sap of the plant, causing leaves to yellow and eventually fall off. To manage spider mites, remove affected leaves and dispose of them properly. Provide adequate humidity around the plant by misting it. Insecticidal soap or neem oil can also be used to manage spider mites, but they should be applied according to the package instructions.
