Bottlebrush (Callistemon)

| I have a bottlebrush tree (3 metres tall) which is approximately 15-20 years of age. About 3 years ago it was pruned roughly and now is showing signs that it is struggling. I'm not sure if there is any possible impact on the tree's health by the pruning, but my guess is that it might be related to the dry conditions experienced in Brisbane, Australia, over the past 2 years. Other native trees we have are all healthy. I have checked for obvious signs of pests or disease, but found nothing. The tree still has some greenery, but it hasn't flowered recently. ANy suggestions to help reinvigorate the tree will be apreciated. |

Any idea which Callistemon you have? Maybe drought could be the problem if it's a native of a very wet part of Australia, though they are usually very drought hardy even then. Sometimes a lot of rain after drought causes a problem.
What about the neighbours? Have you looked around the area to see if there are other callistemons of the same kind, and how they're doing?
The idea that pruning has harmed it don't sound likely. I wouldn't expect a problem from pruning a healthy tree unless it was pruned back very hard, and then it would be more likely to have died in quite a short time, rather than fade away over three years.
Has there been root disturbance? Building done in the vicinity? Change in the mulching regime? (Not everything loves mulch.)
Have you fertilised? If so it could have caused problems.
