Care Guide

Serratula plants are relatively easy to care for and require little maintenance. Here are some tips on how to care for these plants:

• Fertilization: Fertilize in the spring and summer with a balanced fertilizer. Avoid fertilizing in the fall or winter.
• Soil: Serratula plants prefer sandy or loamy soil that is rich in organic matter.
• Sunlight: These plants prefer full sun to partial shade.

Common Pests & Diseases

Serratula plants are relatively resistant to pests and diseases, but may occasionally be affected by the following:

• Aphids: These small insects may cluster on the leaves and stems of the plant, sucking sap and causing distortion and yellowing. Use insecticidal soap or neem oil to control.
• Spider mites: These tiny pests may cause yellowing, stippling, and webbing on the leaves. Use insecticidal soap or neem oil to control.
• Powdery mildew: This fungal disease may cause a white, powdery coating on the leaves. Remove affected leaves and use a fungicide to control.
