When planning to prune bottle brush trees, prune after fading of the flowers and ensure retention of the shrubs’ natural shape or shape it into an umbrella-like top. Remove all suckers and shoots growing on the main trunk or below the canopy, dead or diseased branches, and crossing branches.
Pruning the bottle brush trees after flowers fade promotes future blooms. Retaining the natural shape of the trees make them look better, but some people prefer to shape them into an umbrella-like top. It is prudent to avoid making a meatball when pruning bottle brush trees.
Removing all the suckers or shoots sprouting on the main trunks or below the canopy enables the trees to develop into full, upright branches. It also prevents competition for space, nutrients and water, promoting healthy growth.
It is important to remove the broken, diseased and dead branches any time they appear on the trees even if it’s not during the pruning session. Dead and diseased branches can spread diseases if not eliminated early enough. Prune such branches about 6 inches into the unaffected part. When two branches are crossing or rubbing, retain the healthiest and strongest branch to promote the development of a full, healthy canopy.
