LAWN PLAN EXCLUSIVE

Active Lawn

Nutrients for actively used lawns

Active Lawn delivers 28-0-3 for lawns that get used hard. High nitrogen fuels dense growth to recover from wear. Potassium strengthens roots so grass bounces back. The 5.6% slow-release keeps feeding steadily instead of surging and crashing.

Not for new lawns or stressed grass. This is fuel for lawns already running.

The good stuff inside

  • High nitrogen 28-0-3 NPK Fuels dense growth on high-traffic lawns
  • 5.6% slow-release nitrogen Keeps feeding for weeks, not days
  • Potassium Strengthens roots so grass bounces back
  • Zero pesticide fertilizer—everything you need, nothing you don't
  • Universally loved by climates and grasses

How to use

Apply spring or summer 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.

What does Active Lawn do?

Active Lawn delivers high nitrogen (28-0-3) for dense growth and deep green color. The 5.6% slow-release nitrogen keeps feeding steadily instead of a one-week surge that fades. Potassium strengthens roots for stress resilience. It's built for lawns that get heavy use and need to recover from wear.

How long after Active Lawn can I apply my next fertilizer?

Wait 4-6 weeks between liquid fertilizer applications. Applying sooner risks burning your lawn with excess nitrogen. If you're using granular fertilizer, your wait time in between applications can be found on the product label (each one is slightly different). Mark your calendar so you don't stack applications.

Can I use Active Lawn right after aeration?

Yes. Aeration opens channels for nutrients to reach roots. Apply Active Lawn within a few days of aerating for best results. The nitrogen will move into the soil through the aeration holes. Water lightly after application.

How long after applying Active Lawn should I wait to mow?

Wait until the lawn is completely dry, usually 24 hours. Mowing wet grass after fertilizing can spread the product unevenly and stress the lawn. If you need to mow sooner, at least wait until the fertilizer has dried on the blades.

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.
