Ash is distinguished among our tree species in that they are usually the last tree to unfurl their leaves in spring and the first to drop them in fall.
An interesting thing to note about ash is that it has a very low moisture content. Much lower than practically any of our other tree species. You can actually burn ash right after felling without any seasoning. It won’t burn exceptionally well, but nonetheless it will.
Lastly, ash allows a lot of light filtration through its leaves. It does not have a tightly clustered crown that produces deep shade like many other species. This allows for many gardening opportunities under and around ash trees for an array of vegetables and medicinal plants that thrive in partial shade.
