Pre-emergent is one of the most important aspects of having a weed free lawn. It’s a specialized herbicide that works by blocking the plant’s ability to grow roots. What this means is that any weeds seeds that are currently in your soil like crabgrass and broadleaf weeds will have a much harder time germinating once soil conditions are right.
