A reader recently asked about the practice of shredding leaves prior to using them as mulch. What is the motivation for shredding leaves and what are the benefits of this practice?
The best weapon you have against this annual weed is crabgrass preemergence herbicide (also called crabgrass preventer). You apply this product in the spring before the crabgrass seed sprouts. This granular herbicide works by creating a chemical barrier at the surface of the soil. As the seeds begin germination, they take in the herbicide and die.
