We have all probably seen the tree that is five or six years old and still has the wooden poles for support still tied to them. Usually the pole has been pulled out of the ground and the wires holding it to the tree are squeezing the trunk.
This is a good analogy for life and of course landscaping. The poles are there to help support the tree, but if left too long it can actually hamper the tree’s growth or eventually kill it.
The best point to take those supports out is before the wires get even close to squeezing the trunk and the tree has deep enough roots to support it even during harsh conditions.
So whether in life or in landscaping, supports are necessary and important but shouldn’t get in the way of true growth.
