Why your schedule depends on your ZIP
A Milorganite schedule in Cleveland is not a Milorganite schedule in Atlanta. Cool-season lawns feed hardest in spring and fall and skip summer nitrogen in hot regions. Warm-season lawns feed through summer and stop before their fall dormancy. The calculator shifts each product's application windows using your region's frost dates and growing season.
Cool-season lawns
Feed hardest in spring and fall. In hot regions the calculator drops summer nitrogen entirely, because feeding heat-stressed fescue or bluegrass does more harm than good.
Warm-season lawns
Feed from full green-up through late summer. The last application lands about 6 weeks before dormancy, so late-fall feedings are dropped automatically.
Your region
Northern ZIPs shift every window later; southern ZIPs shift earlier and open a longer season. The same product gets a different calendar in each region.
Scotts Turf Builder Southern Lawn Food questions, answered
When should I feed a Southern lawn?
Start at full green-up in spring, feed through summer, and finish with an early-fall application about 6 weeks before dormancy. Warm-season grass cannot use a late-fall feeding, so the calculator drops it.
How much Scotts Southern Lawn Food do I need?
The label rate is about 2.8 lbs per 1,000 sq ft, so a 5,000 sq ft lawn uses one 14 lb bag per application. The calculator scales it to your lawn size.
