To use natural grass fertilizer, follow the instructions on the product packaging for proper application rates and timing. Generally, you would spread the fertilizer evenly over the lawn using a spreader, water the lawn after application, and avoid mowing for a few days to allow the fertilizer to be absorbed. Make sure to choose a fertilizer that is appropriate for your grass type and the specific needs of your lawn.

You should do this the other way around ... mow it first then apply the fertilizer. Otherwise you are just putting all that fertilizer into the grass catcher of the mower.
