Simple Lawn Solutions 16-4-8 calculator

Simple Lawn Solutions Advanced 16-4-8 is a liquid lawn food applied at 10 fl oz per 1,000 sq ft through a hose-end sprayer. Because it is liquid, this tool reports fluid ounces and bottles instead of bags. Enter your lawn size and ZIP for the amount and a light, frequent feeding schedule.

Label rates at a glance

Every product below has its own label rate and application limit. The calculator uses the label rate as the source of truth and reports the nitrogen it delivers, so you can compare products fairly.

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 genuinely different calendar.

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.
