Eucalyptus Tree Problem

Question

We have moved into a house with beautiful Eucalyptus trees in the garden. Since the hard frosts of last winter, some of the trees have  dead looking leaves with spots. On one tree the bark is stripping away.

Answer 1

This is damage that is consistent with cold damage. If the trees are still alive they should recover. Watch them carefully over the next few months while they recover as pests and disease are more likely to attack plants that are already stressed. As a preemptive measure, you can treat the trees with neem oil. This will help keep pests and fungus from attacking the plant.
