Crabgrass Control Plus 0 - 0 - 7 with 0.37% Prodiamine Herbicide can be applied to lawns, ornamental turf (excluding golf course putting greens), landscape ornamentals, and established perennials and wildflower plantings. The mulch may prevent the product from reaching the soil area where it needs to be watered in to prevent those weeds from germinating so mulching should be done after application.
