Usage Instructions


For best results apply before 10 am, or after 5 pm. Application during the afternoon should be avoided.

Avoid mowing your lawn 24 hours prior to and after application to ensure proper uptake of Green-Up.

Application should be repeated every three to six weeks, or on an as-needed basis.

Please ensure your lawn is on a suitable watering schedule. Water is essential to a healthy lawn and proper uptake of nutrients.

The included sprayer will automatically mix LawnStar Green-Up with water and dilute it at the proper rate.

1. Shake product well before use

2. Attach sprayer to a standard garden hose. Switch on water supply

3. Turn sprayer to the “ON” position. Important note: Push in plastic safety tab before attempting to adjust dial

4. Slowly apply the spray in a side-to-side motion, being sure to cover the area evenly. Aim to apply at a rate of 5–10 oz. per 1,000 sq. ft.

For less severe deficiency/maintenance, apply 5 oz. per 1,000 sq. ft.
For more severe nutrient deficiency, apply 10 oz. per 1,000 sq. ft.

Product contains iron, which can severely stain concrete, clothing, and other surfaces. Apply with caution. Shake product well before use.
