A seed and fertilizer mix for lawn sections

Scotts Turf Builder Rapid Grass Sun & Shade Mix is a grass seed and fertilizer product for new grass and overseeding. The 5.6 pound bag is designed for spring or fall seeding when soil and air temperatures support germination.

This product belongs in a planned lawn session. Rake the surface, measure the area, set the spreader from the label, apply the mix, and keep the soil surface moist while seedlings begin to grow.

The label gives spreader settings

The label includes settings for Scotts hand-held, broadcast, drop, Wizz, and Elite spreaders. That guidance matters because the bag is made for an even pass across a measured lawn section.

A handheld spreader can suit defined strips and patch edges. A compact broadcast spreader can suit open grass sections where the gardener can walk a clear route.

The coverage depends on the seeding job

Scotts lists the 5.6 pound bag at 839 square feet for new lawn seeding and 2,800 square feet for overseeding. Those coverage numbers guide the product amount for each lawn task.

Use the label to match the rate to the job. After application, a soft watering pattern helps the seed settle and keeps the surface evenly damp.
