- Spider mites: These microscopic pests feed on the leaves of the plant and cause yellowing and webbing. To manage a spider mite infestation, wash the leaves with a mixture of 1 tablespoon of dish soap and 1 quart of water.
- Mealybugs: These waxy pests feed on the plant sap and can cause yellowing and stunting of the plant. To manage a mealybug infestation, spray the plant with a mixture of 1 tablespoon of rubbing alcohol and 1 quart of water.
