What pests commonly affect eucalyptus outdoor flower boxes?

Eucalyptus plants in outdoor flower boxes can attract various pests that may harm their growth and appearance. Some of the most common pests include:

1. Psyllids (Eucalyptus Gall Wasps): These tiny insects cause leaf discoloration and galls, weakening the plant over time.

2. Aphids: They suck sap from leaves, leading to curling and yellowing, while also secreting sticky honeydew.

3. Scale Insects: These pests cling to stems and leaves, causing wilting and stunted growth.

4. Spider Mites: They create fine webbing and cause speckled, dry leaves by feeding on plant juices.

5. Caterpillars: Certain species chew on leaves, leaving holes and defoliating the plant.

To manage these pests, regularly inspect your eucalyptus, use insecticidal soap or neem oil, and encourage natural predators like ladybugs. Proper watering and pruning also help maintain plant health and reduce pest infestations.
