Princep Liquid Herbicide is a pre-emergent that is safe to use on established turfgrass and ornamentals per the product label. If there were to be damage to existing plants, or shrubs then you probably would have already noticed it by now. We always recommend reading the product label completely before applying herbicides to be sure it is safe and appropriate for your desired application.
