Question From: Mamaroneck, New York, United States
Q: Is it advisable to use wiltpruf on arborvitae to protect them in the winter months?
A: If your arbs are subject to wind burn or salt damage the Wilt Pruf may help. Problem is the temps must be in the 40s for at least 4 hours when you apply it. That may not happen until January, if then. Best And Happy Yardening, Nancy.
