Want to know what a tree word means? We'll get you started with this A-L glossary of tree terms.

Since we are going to be discussing how to care for trees in some of our blogs, we thought it would be a good idea to give you a glossary of some of the tree terminology that we’ll be using so that you understand it a bit better. In our future blogs, we’ll refer back to this post and the L – Z post so that you don’t have to go back and look for it.
