It can stunt growth and weaken the plant, making it susceptible to other diseases. To manage this disease, remove any infected parts of the plant and apply a fungicide. It is also important to improve air circulation around the plant by spacing it out and not overwatering.
2. Root Rot: Overwatering or poorly draining soil can lead to root rot, a fungal disease that causes the roots to rot and die. This can weaken the plant and stunt its growth. To manage this disease, ensure that the soil drains well and avoid overwatering the plant. If root rot is detected, remove any infected roots and repot the plant in fresh soil.
3. Leaf Spot: This is a fungal disease that appears as dark spots on the leaves. It can weaken the plant and cause it to drop its leaves prematurely. To manage this disease, remove any infected leaves and apply a fungicide. It is also important to water the plant at the base, avoiding getting water on the leaves.
Pests
1. Aphids: These are small insects that suck the sap from the plant, causing stunted growth and distorted leaves. They also leave a sticky substance called honeydew, which attracts other pests like ants. To manage aphids, remove them from the plant by spraying it with a strong jet of water or by applying an insecticidal soap. It is also important to control ant populations as they protect aphids from natural predators.
2. Spider Mites: These are tiny pests that suck the sap from the plant, causing yellowing and wilting of leaves. They also produce webbing on the plant, which can further weaken it. To manage spider mites, spray the plant with a strong jet of water or apply an insecticidal soap. It is also important to improve humidity around the plant by misting it frequently.
3. Whiteflies: These are small insects that feed on the underside of the leaves, causing yellowing and weakening of the plant.
