Scotts Weed & Feed calculator

Scotts Turf Builder Weed & Feed goes down at about 2.9 lbs per 1,000 sq ft, at most twice a year. It follows weed activity, not just grass growth: apply to damp grass with weeds actively growing, and wait 4 weeks before overseeding. Enter your lawn size and ZIP for the amount, bags, and timing.

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.

Scotts Turf Builder Weed & Feed questions, answered

How much Scotts Weed & Feed do I use?

The label rate is about 2.9 lbs per 1,000 sq ft, so a 5,000 sq ft lawn uses roughly one 14.3 lb bag per application. The calculator scales it to your lawn size.

When should I apply Scotts Weed & Feed?

Apply when broadleaf weeds are young and actively growing, usually spring, with an optional early-fall pass. Grass should be damp (morning dew or a light watering) so the granules stick to weed leaves. Do not apply more than twice a year.

Can I seed after applying Weed & Feed?

No. Wait at least 4 weeks after a weed & feed application before overseeding, and do not apply it to newly seeded lawns until they have been mowed 3 to 4 times.
