Lawn with all-nitrogen food with 30 to 40 percent of that nitrogen in slow-release (encapsulated or coated) form. Turf experts tell us this fall feeding is critical.

Pre-emergent granules must be applied soon (hopefully by September 10) to prevent germination of annual bluegrass, rescuegrass, and ryegrass. Safe on any lawngrass if it's been planted for 6 or more months. Do not use if you intend to overseed with rye or in areas where you will be sowing wildflower seeds.
