Our overzealous volunteers decided to "prune' the native trees at our croquet club. We were told this encourages growth and from last year have a row of meatballs (no flowers) to prove itl Last Saturday before anyone came they chainsawed all the established bottlebrush trees, wattle trees, and one tall paperbark (flowering) back to trunks. All branches, all foliage and the crown removed. The filtered shade totally gone from the garden beneath which is planted out in small shrubs and annuals. What is likely to happen now? Can the damaged trees be helped in any way? Oh yes, the 'meatballs" from last year's attack were also trimmed by chainsaw. We back onto a reserve and until now have had lots of native birds. Can I please have a strongly worded opinion to quote at the nest Annual Meeting please. This needs a huge change in club rules.
My advise is wait and see.
Do not try to fertilize the trees into health. If they began to actively growing you can then, lightly fertilize.
You could consult with an Arborist to determine the health of the severely pruned trees.

We had a cold winter this year in Houston and caused a lot of the bottlebrush to turn brown. It is May and there is little green in the plants. Can I prune all the dead leaves? How can I tell which ones will survive and which ones will not.
You can prune it back. This article will help:

I have a young bottle brueh in a pot but the leaves are a little brown on the edges
You may either be overwatering it or under watering it. Brown tips in container plants is generally a symptom of a problem with watering
I would like to prune my bottlebrush trees severely, maybe down to only one or two feet. Will they grow back as bushes?
You should prune the plant back by 1/3 at a heavy prune.

Recently a section of our bottlebrush tree started to die. We also lost a branch from another section of the tree after a storm. Up until recently the tree was doing just fine. It was blooming tho not as much as in other years. Any ideas what is going wrong? Thank you.
Bottlebrush trees are fast growing and their branches can be brittle. It may have sustained some damage in the storm you mention.
