LAWN PLAN EXCLUSIVE

Pouch of Super Nitrogen

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.

The good stuff inside

  • Maximum nitrogen 30-0-0 NPK Our highest dose for lawns that need it
  • 5.8% slow-release nitrogen Reduces burn risk, extends feeding
  • Zinc Helps grass process high nitrogen efficiently
  • Zero pesticide fertilizer—everything you need, nothing you don't
  • Universally loved by climates and grasses

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.

When should I use Super Nitrogen instead of Active Lawn or Mighty Green?

When your lawn needs maximum feeding. Large properties where standard formulas don't keep up, bermudagrass that grows aggressively in summer, or high-traffic areas that need constant recovery. Super Nitrogen delivers 30% nitrogen versus 26-28% in other formulas. If your lawn looks hungry two weeks after fertilizing, this delivers more fuel.

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.

Worked for us!

Great results. We've had trouble with our lawn for years, but since using Get Sunday it has steadily improved. We have grass growing where it NEVER has before regardless of how much time, effort, fertilizer, or other product I've used. We would highly recommend. Give this a shot.

Looking good so far!

So far everything is looking very healthy and happy especially as it starts to cool off. The lawn is pretty lush except in a few areas where I'll probably have to add more seed since it's Fall. The shipments, instructions and application of the products have been a breeze. Now I'm ready to try more!

It really works!

I am amazed to see the growth and turnaround we have had from using Sunday. From completely dead areas to long strong blades of lush green grass! We still have some bald spots but we will continue to use Sunday because it has actually worked wonders!

Absolutely amazing

I was fighting a battle with pocket gophers and pets. My yard was great in a few spots but the majority was either not growing, always dead or just sad. I gave Sunday a chance and was amazed. After I got the gophers under control, I started my lawn plan and could not believe the results. There's sti...

Front yard looks like new sod

A friend asked when I got new sod put in. After just a couple of months of Sunday treatments, my yard looks like new sod.
