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.
Simple Lawn Solutions Advanced questions, answered
How much Simple Lawn Solutions do I need?
The label rate is 10 fl oz per 1,000 sq ft, so a 32 oz bottle covers about 3,200 sq ft per application. The calculator reports the fluid ounces and bottles for your lawn size.
How often can I use a liquid lawn fertilizer?
Liquid lawn foods are made for lighter, more frequent feeding, roughly every 4 weeks during the growing season, up to 6 times a year.
