DON'T LET THOSE BLACK LEAF SPOTS STUNT YOUR TREE'S GROWTH OR LEAD TO EARLY LEAF LOSS
What Is The Cause Of My Tree's Illness?
Black leaf spot is common on aspen and cottonwood. Small brownish spots appear on infected leaves in late July and early August. The spots later enlarge and turn blackish, are of various sizes and irregular in outline, and have a yellowish to golden border. Infected leaves fall prematurely. The cause is a fungus found on aspens, cottonwoods, and other poplars.
Dangers Of Black Leaf Spot
Initially leaves develop brown spots that turn black over time. These spot stunt tree growth and cause leaves to drop early in the fall.
How To Treat Black Leaf Spot
It’s very important to break the cycle of carrying over infected leaves from year to year. Make sure to rake and destroy infected leaves each year, and do not let your sprinklers wet the leaves on aspens and cottonwoods. There are fungicides to treat this disease as either a foliar spray or a soil drench. Call Utah Tree Doctor for details.
