Ingredients

Nitrogen drives fast, dense grass growth and rapid green-up across your entire lawn.

Potassium strengthens water management and helps your lawn hold up through heat and drought.

Seaweed extract builds stress resilience so your grass stays steady when temperatures climb.

Iron delivers deep, rich greening without pushing excessive top growth.

How to use

For best results, apply early morning or evening between 50 and 85 degrees F. Make sure your lawn is well hydrated. Avoid use on drought-stressed or heat-stressed lawns.

Connect the universal hose-end sprayer to your garden hose and attach the fertilizer pouch.

Turn on the water and apply evenly across your lawn until the pouch is empty, about 10 to 15 minutes.

Reapply every 4 to 6 weeks from spring through fall.

Keep the sprayer for future applications.

How often should I apply Grass Powerhouse to my lawn?

Grass Powerhouse Liquid Fertilizer should be reapplied every 4 to 6 weeks from spring through fall while your grass is actively growing.

Apply when temperatures are between 50 and 85 degrees F. Skip applications during drought or when your lawn is heat-stressed.

Can I apply Grass Powerhouse after using weed control products?

Let Grass Powerhouse Liquid Fertilizer dry fully, about 1 to 2 hours, before applying anything else. For weed control, wait 24 hours after it dries.

For seeding, apply Grass Powerhouse first and seed once dry, or wait until new grass has been mowed at least once.

Will Grass Powerhouse burn my grass if I apply too much?

Grass Powerhouse Liquid Fertilizer can cause burning if applied too often or to stressed grass. Stick to every 4 to 6 weeks and skip applications when your lawn is heat-stressed or drought-stressed.

When in doubt, water your lawn first and wait a few days before applying.

What is the difference between Grass Powerhouse, Lawn Strong, and Iron Boost?

Grass Powerhouse Liquid Fertilizer is a high-nitrogen 24-0-3 formula for fast, dense growth and deep greening. Lawn Strong pairs nitrogen with molasses for soil health. Iron Boost adds extra iron for even deeper color.

All three work together. Many customers rotate them through the season.
