Common diseases:
1. Root Rot: Overwatering or poorly-draining soil can lead to root rot, which can cause the plant to wilt, discolor, and die. To avoid this issue, make sure the soil is well-draining and avoid overwatering. If root rot occurs, remove the affected parts of the plant and repot in fresh, well-draining soil.
2. Leaf Spots: Leaf spots are caused by fungal or bacterial infections. Symptoms include discoloration and holes in the leaves. To prevent leaf spot diseases, avoid watering the leaves and provide good air circulation around the plant. In case of infection, remove the affected leaves and treat with a fungicide or bactericide as per the manufacturer instructions.
Common pests:
1. Mealybugs: These pests usually appear as white, cottony masses on the stems or undersides of leaves. They suck the sap from the plant, causing it to weaken and become discolored. To get rid of mealybugs, use a cotton swab dipped in rubbing alcohol to remove them from the plant. Repeat this treatment until all mealybugs are gone.
2. Spider mites: Spider mites are tiny arachnids that can be difficult to spot, but if present, they can cause yellowing and weakening of the leaves. To manage spider mites, spray the plant with water to increase humidity and wash them off. Alternatively, use insecticidal soaps and follow the manufacturer instructions carefully.
3. Scale insects: These pests look like small bumps on the plant stems and leaves and can cause significant damage to the plant by sucking sap.
