Common Pests & Diseases

Salix Humilis is generally resistant to pests and diseases, but it can still be affected by some common problems:

• Aphids: These small, soft-bodied insects can suck the sap from the leaves, causing them to wilt and curl. Use insecticidal soap or neem oil to control infestations.
• Mites: These tiny pests can cause yellowing and stippling of the leaves. Use a miticide to control infestations.
• Canker: This fungal disease can cause dieback and cankers on the branches. Prune affected branches and apply a fungicide to prevent further spread.
• Root Rot: This fungal disease can cause yellowing and wilting of the leaves, as well as stunted growth. Improve drainage and avoid overwatering to prevent root rot.
