Why are multiple trees in my yard dying?

My recommendations for you would be to provide it with a good fertilizer this fall and spring to promote establishment. You will also need to monitor the soil to make sure that it stays moist. Generally not a big need during the fall, winter, and spring, I would also recommend watering well if we were to experience a deep freeze. This will help to protect the roots. There is not much you can do in regard to the new sprouting of the leaves except promote health and vigor in the tree.
