Common Problems with Hydrangea

Hydrangea paniculata is a hardy plant but can still face a few common problems. Here are some issues that gardeners may encounter:


Although not prone to pest infestations, Hydrangea paniculata can attract unwanted visitors:

●  Aphids: These small, soft-bodied insects cluster on the undersides of leaves, sucking the sap and causing leaf curling and yellowing.

●  Spider mites: These tiny pests can be difficult to spot. They cause yellowing leaves and develop fine webbing.

●  Scale insects: These insects appear as small, raised bumps on stems and leaves, leading to yellowing and wilting of leaves.


While generally resistant to most diseases, Hydrangea paniculata can still be affected by common issues:

●  Powdery mildew: This fungal disease creates a white, powdery coating on leaves and flowers, caused by high humidity and poor air circulation.

●  Leaf spot: This fungal disease results in brown spots on leaves that may turn yellow and fall off. Wet leaves and poor air circulation cause it.

●  Bacterial wilt: This disease causes sudden wilting and death of the plant caused by bacteria in the soil, and there is no cure.

If you notice any of these problems with your Hydrangea paniculata, take quick action to prevent further damage. Remove affected leaves or flowers and use an appropriate pesticide or fungicide if necessary.
