If we lay perfectly still for weeks and months, we know that our joints will stiffen and become less flexible. Movement will become difficult. Bending will hurt. Holding perfect still is bad for our health. And it’s bad for trees as well. Yet, every year hundreds of trees are splinted into immobility by well-intentioned gardeners. It’s no better for them than it is for us.
We have a tendency to regard a newly planted sapling as fragile, and we want to protect it as best we can. That trunk looks so flimsy, as if the first breeze will snap it in two. So what do we do? We stake it so it can’t wiggle. And that’s a very bad idea. Movement causes trunks to enlarge and strengthen. Trees that are firmly staked will never become strong.
