Trees in nature can be pruned. This can lead to healthy and immense growth.
Trees can also be topped. This can have devastating effects.
Topping a tree, or lobbing off the top of the tree, has the potential to remove up to 100% of the leaf-bearing crown. This strips the leaves that function as food for the tree, forcing the tree to desperately try to quickly create new growth. If the tree's energy stores are low this can have dangerous consequences.
How are you like a tree? What is the difference for you between pruning and topping?
Consider your practice challenge:
What did your energy stores look like? Where did the real learning take place?
