Super Nitrogen Liquid Lawn Fertilizer (42.3 fl oz)

Maximum nitrogen for lawns that need it

Super Nitrogen is exactly what it sounds like. Our highest nitrogen formula at 30-0-0, built for lawns that burn through nutrients fast. High-traffic yards, large properties, warm-season grasses that grow aggressively in summer. Zinc helps the plant process all that nitrogen efficiently and reduces burn risk.

This isn't for every lawn. It's for lawns that eat fertilizer for breakfast.

How to use

Apply during the growing season when grass is established. Avoid applying to new lawns or stressed grass.

1. Apply early morning or evening to a well-hydrated lawn.

2. Connect sprayer to hose and pouch.

3. Spray evenly until pouch is empty (about 10-15 minutes).

4. Reapply every 4-6 weeks during active growth.

Can too much nitrogen damage my lawn?

Yes. Over-fertilizing causes excessive top growth at the expense of roots, increases disease susceptibility, and can burn grass. Super Nitrogen includes 5.8% slow-release and zinc to reduce burn risk, but follow application rates. Don't apply more often than every 4-6 weeks.

What does zinc do in Super Nitrogen?

Zinc helps grass process nitrogen efficiently. Without enough zinc, nitrogen builds up faster than the plant can use it, increasing burn risk. The zinc in Super Nitrogen supports healthy uptake so you get the benefits of high nitrogen without the downside.

Is Super Nitrogen safe for all grass types?

For established lawns, yes. Bermudagrass, St. Augustine, and other warm-season grasses handle high nitrogen well. Fine fescue prefers less. Kentucky bluegrass tolerates it. Know your grass type before applying. And avoid new seedlings—they need phosphorus, not heavy nitrogen.
