Ingredients

Nitrogen (15%): Fills in and thickens your grass by driving leaf and blade growth across your whole lawn.

Iron: Delivers that deep, rich green color you notice from the street. Your neighbors will notice it too.

Potassium (3%): Helps your lawn hold onto water and bounce back from heat, foot traffic, and dry stretches.

Seaweed: Supports greening and long-term turf resilience. Think of it as a multivitamin for your lawn.

How to use

Apply early morning or evening when temperatures are between 50 and 85 degrees F. Avoid using on drought-stressed or heat-stressed lawns.

1. Connect the hose-end sprayer to your garden hose and attach the 42 fl oz pouch.
2. Turn on the water and walk your yard, applying evenly until the pouch is empty. This takes about 10 to 15 minutes.
3. Once the liquid has dried on the grass, you're good to get back on your lawn.
4. Reapply every 4 to 6 weeks from spring through fall for steady feeding all season.
5. Keep the sprayer for future use. Let liquid fertilizer dry completely before applying other products like weed control or grass seed.
