Can you use Casoron 4G around aspen trees and vibernum bushes?
Yes, you may use Casoron 4G around trees and bushes. Casoron 4G is a selective pre-emergence herbicide that kills variety of weeds and grasses before they emerge from the ground, by forming an herbicidal vapor barrier in the upper layer of the soil when activated by rainfall or irrigation water.
