Tip #7: White Ash (Fraxinus americana)
Decades ago, the White Ash reigned supreme as the quintessential American shade tree, offering exceptional hardwood strength, majestic canopies, and brilliant autumn color. Today, planting an ash tree guarantees immense frustration and inevitable financial loss due to a single, unstoppable insect: the Emerald Ash Borer. Since its discovery in North America, this tiny, metallic green beetle has slaughtered tens of millions of ash trees across the continent, boring into the trunk and completely destroying the vascular system of the tree.
If you plant a White Ash today, you invite a ticking pest-control bill directly into your yard. Keeping an ash tree alive requires expensive, ongoing systemic insecticide treatments applied by certified arborists every one to two years for the entire life of the tree. If you lapse on these costly treatments, the tree will die rapidly, becoming incredibly brittle and hazardous almost immediately. Incorporating an ash into your modern garden plan ranks among the most critical tree planting mistakes you can make. Rely on alternative large shade providers instead; the White Oak, Hackberry, or American Linden offer spectacular beauty and longevity without the imminent threat of total insect devastation.
