As far as targets go I have this section for you on pruning. Often myrtle
is topped and people claim it was pollarded - not true.
Mulching correct also will also correct. I am willing to help you anyway I
can.

If you would like to get more technical I recommend MODERN ARBORICULTURE,
the book. It can be obtained at your library or they can get it for free.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.
Some people will buy products they do not understand and not buy books that
will give them understanding.

I live in bristol uk I have a bottle brush plant that has flowered well

should i use ?

Is your bottle brush Callistemon or Melaleuca? Both are in the myrtle
family and are native to Australia.

The flowers on Callistemon generally last only one season, so last
year's flowers should already be history. Callistemon can be pruned
severely, especially now before summer comes. However, prune only to
above green foliage; pruning below the lowest green leaf may cause the
entire branch to die (similar to pruning lavender). Pruning is not
really necessary except for aesthetic purposes or to remove deadwood.

I'm not familiar with the care of Melaleuca. However, I know that it is
considered an invasive pest in Florida.
