Pro Tips for Best Results

Check The Forecast

Avoid applying before heavy rainfall so particles don't get washed away.

Mow First

Clear any lawn debris and make it easier for particles to reach the soil.

Clean Up

Sweep or blow product off the driveways/sidewalks back into the lawn.

Water Deep

Your lawn will need at least 0.2 inches of water.

Don't Bag It

Leave lawn clippings for at least one mowing to avoid particle pick-up.

Spreader Settings

We recommend using a broadcast spreader. These spreader settings are a guide. Many variables such as walking speed, terrain, particle size, density, and spreader condition can affect these settings. Be sure to calibrate your spreader before every application.
