Eucalyptus cinerea trees are rapid growing evergreens that can reach a height of 60 feet, and a width of 15 when growing in a sunny, well-drained location. These trees are commonly known as eucalyptus to most gardeners and are highly praised for their beautiful blue-green foliage. Eucalyptus trees can easily survive pest infestations and drought, which makes them popular garden trees, but like most other trees, pruning is required to keep them healthy and looking their best.
Prune the eucalyptus tree in the spring season or during the fall before the first frost of winter. Do not prune the eucalyptus tree during the summer. Summer heat can cause the tree to wilt quickly when the ends of its branches are exposed.
Prune the ends of overgrown branches to keep the eucalyptus tree looking uniform. Heavy pruning is not necessary. Simply cut overgrown branches back level with the other branches of the tree, using pruning shears or garden loppers.
Cut away dead, dying or diseased branches of the eucalyptus tree using garden loppers or your pruning shears on smaller branches. Cut these branches off where they join the main trunk of the tree.
