Most routine tree pruning such as removing weak, diseased or dead limbs can be carried out at any time of the year with little or no effect on the tree. As a guide, growth is maximized and wound healing is fastest if pruning is done before the spring growth occurs.

Heavy pruning of a tree, however, should be done before Spring time. During Spring, trees expend a great deal of energy producing new growth. Heavy pruning after this time can stress the tree.

Some climates, such as in parts of the tropics and Australia, dont have a distinct four seasons. So, when to prune then?

Prune in the dormant season if possible. This may be be the dry season in the tropics or winter other areas.

The best time to prune most deciduous trees is late autumn early winter, prior to new bud development.

Ideally have your local Arborist or tree service company provide a tree pruning program, so you can co-ordinate pruning at the most appropriate time.
