Succulents, with their unique shapes and textures, are a popular choice for indoor and outdoor gardens. However, like any plant, they can be susceptible to pests and diseases. Understanding the common culprits and knowing how to treat them can help you maintain healthy and thriving succulents.
Common Pests Affecting Succulents
- Mealybugs: These tiny, cottony insects often cluster in the crevices of plants. They feed on plant sap, causing stunted growth and yellowing leaves.
- Scale Insects: These small, hard-shelled insects attach themselves to the plant’s stem and leaves. They suck sap, leading to weakened plants and discolored leaves.
- Spider Mites: These tiny arachnids create fine webs on plants. They feed on plant sap, causing yellowing leaves and stunted growth.
- Aphids: These soft-bodied insects cluster on young growth and feed on plant sap. They can cause yellowing leaves, stunted growth, and honeydew production.
Common Diseases Affecting Succulents
- Root Rot: Caused by overwatering or poor drainage, root rot leads to mushy roots and yellowing leaves.
- Powdery Mildew: A fungal disease characterized by white, powdery patches on leaves and stems. It thrives in humid conditions.
