Hey guys, I was at a customers house the other day giving him an estimate, and he pointed out to me that some of his hedges are turning yellow. I can think of the name off the top of my head though of the plant. They are about 2-4 feet tall, evergreen like with really soft foliage. Anyways I trimmed all his shrubs last year, and it only is happening to a select few of them, mainly in the back of the property. I was thinking it was maybe winter burn or wind scorch. Today I happened to go outside, and notice it was happening to a few of mine as well. Its affecting the top of the plant, turning it this yellowish brown color. Any ideas on what could be going wrong, and how I should approach fixing the problem. When would be the best time to put down a fertilizer to fix these plants, I am in S.E. Wisconsin and the ground really hasnt thawed yet.
