LAWN PLAN EXCLUSIVE

Mighty Green

Slow-release nitrogen for color that lasts

Mighty Green delivers 26-0-2 with high nitrogen for dense growth and potassium for resilience. The difference is the 10% slow-release nitrogen. Instead of a quick surge that fades in two weeks, it keeps feeding so color holds longer between applications.

Deep rooting. Deep greening. And it sticks around.

The good stuff inside

  • High nitrogen 26-0-2 NPK Dense growth and deep greening
  • 10% slow-release nitrogen Color that lasts between applications
  • Potassium Deep rooting and heat tolerance
  • Zero pesticide fertilizer—everything you need, nothing you don't
  • Universally loved by climates and grasses

How to use

Apply spring through fall when grass is actively growing. Temps 50-85°F.

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. Let dry completely before walking on lawn.

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

How long after applying Mighty Green should I see a difference?

Most lawns show visible greening within 5-7 days. The quick-release nitrogen works fast. The 10% slow-release continues feeding for weeks, so color should hold longer than fertilizers without slow-release. Full results depend on watering and weather.

Should I water my lawn after applying Mighty Green?

Wait 24 hours before watering or running sprinklers. The fertilizer needs time to dry and absorb. If rain is expected within 3 hours, wait for a drier day. Light rain after 24 hours is fine and helps move nutrients into soil.

How long do I wait to apply Mighty Green after seeding?

Wait until new grass has been mowed 2-3 times, usually 4-6 weeks after germination. Applying Mighty Green too early can burn tender seedlings.

Can I apply Mighty Green before or after aerating?

Either works. Applying after aeration lets nutrients reach roots through the holes. Applying before is fine too. Just don't aerate immediately after applying or you'll disrupt the fertilizer before it absorbs. Wait 2-3 days between application and aeration.

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!

Lawn definitely looks better, but I am still dealing with bare spots. I've attached a photo.

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.
