Q.River Birch Tree
My tree grows so tall and very little leaves. If I cut the top of tree down, does it continue to grow and more leaves will come out? Thank you so much.
Removing the top of a tree, or "topping", is not recommended because it will harm the tree's health and appearance. Instead, it is much better to let the tree grow in its natural form.
The tree may have had few leaves this year, potentially because of difficult weather conditions, but it will probably grow more leaves next year. See this article for more information:
