Yellow nutsedge is often mistaken for crabgrass. However, the growth and control and treatment of yellow nutsedge is very different from crabgrass. Unlike crabgrass, there is no pre-emergent product available to help minimize the population of this plant.
Ground Ivy, Wild Strawberry, & Wild Violet can be considered some of the most difficult-to-control weeds in a lawn. They can drive homeowners crazy with their efforts to rid their lawns of these weeds with little or no success. The key to getting rid of ground ivy and wild violets is knowing the best time to apply control products.
The best weapon you have against this annual weed is crabgrass pre-emergence herbicide (also called crabgrass preventer). You apply this product in the spring before the crabgrass seed sprouts. The product forms a barrier over the soil surface that helps to suppress the crabgrass seeds from germinating.
