Look around your neighborhood, and you will probably find a tree stump were a large Green Ash or American Ash shade tree has been removed, killed by the invasion of the Emerald Ash Borer. We have lost some of our best shade trees to this pest. As a consequence, we have been planting young trees to replace our future shade canopy.
We are in a serious drought in this area; you have had to water your garden, and perhaps your potted planters. Do not forget about that young replacement shade tree you have planted. It takes years to grow a big shade tree. The first five years require regular weekly watering, especially during this drought. Neglected young trees will not survive the winter, so weekly watering NOW, while they still have leaves, is critical to preserve your investment. Young trees, 2-5 years old, may appear to be doing well, but they have yet to establish the deep roots to make it through this drought, without our help. Even their big brothers are going to need watering because of this extreme drought. Look closely and you will find landscape trees, even ten years old, showing die-back and stress, due to this drought.
