Common Pests & Diseases
The Marmalade bush is generally not susceptible to many pests or diseases. However, here are some issues to look out for:
- Aphids: These small insects can suck the sap from the plant and cause stunted growth and yellowing leaves. Use insecticidal soap to control them.
- Spider mites: These tiny insects can cause yellowing and stippling of the leaves. Use a miticide to control them.
- Root rot: Overwatering can cause the roots to rot, which can lead to wilting and yellowing of the leaves. Avoid overwatering and make sure the soil has good drainage.
