have a red bottlebrush tree flowering beside our house which is
2.5m tall. Only the top seems to flower and the sides have clusters
of cones. How can I encourage the tree to flower all over? Should
I be pruning it?
you should be pruning your bottlebrush to encourage fresh growth
and a bushy habit. However, prune it back carefully. Don't be too
severe. Cut it back by up to a third, section by section, until
you get the shape of tree that you want. It may take several years.
