Mowing your lawn at the right time is important when it comes to getting the best results from your fertilizer application. A good cut before you add fertilizer to your lawn will help to ensure that excessive growth and debris is removed, leaving behind healthy grass to work with. An application usually coincides with watering the grass well so that the nutrients can be absorbed quickly and easily. Wait a few days for the grass to dry and thicken before you mow again. If you are in the midst of a dormant season, you might have to wait up to a week or two before your lawn is ready for its next cut.\r
