Granules are easy to apply evenly with a properly calibrated lawn spreader, and any leftover product simply stores in a cool, dry location until its next use. Pre-emergent or post-emergent weed-and-feed applications for lawns often come as granules.

After you figure out how to get rid of crabgrass it’s important to know how to prevent it from returning. Once you remove crabgrass plants, don’t leave them exposed on the ground. Instead, put them in trash bags so that their seeds don’t spread.

This keeps new seeds from germinating. A good choice is Bonide Sedge Ender Nutsedge & Crabgrass Killer.
