We got our trees trimmed. This is the back one.
It’s weird to think about how trees in your yard are artificial. They’re natural things, but you have to take care of them in a way that’s not natural. For example, clearing out dead branches and crossing branches so that there’s space for the inner branches to get light and not die off.
In the forest, non-optimal growth that will eventually kill off parts of the tree or the entire tree is fine. That tree may die, but it’ll feed other things so the other trees can thrive.
In your yard, assuming you don’t have a private grove, you’ve only got a few trees, so you have to keep it alive.
