Giant eucalypts have a habit of dropping heavy branches earning them the nickname of Widow Maker. These gum trees preserve their health during periods of drought or inadequate water supply by allowing some branches to dry out and break off – a sort of self pruning.

In the top of new shoot, and in the bottom of a root, a cluster of cells are found that are continually dividing and therefore responsible for new growth.
