I think it would be nice if the trees that we plant don’t all grow to the maximum size over time. It is impossible to replant an organic looking forest if every tree regrows to the maximum size. They all look the same and are significantly larger than the natural trees surrounding.
My proposal would be that tress are given some meta data on plant that determines their maximum growth size. This way you can replant tress if they haven’t grown to your liking, or cut down the large ones if you want a smaller forest.
