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

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 are the Sunbelt states in the United States?

The Sunbelt stretches across the southern tier of the country: Florida, Georgia, South Carolina, Alabama, Mississippi, Louisiana, Texas, New Mexico, Arizona, Nevada, and Southern California. These states share long growing seasons, intense summer heat, and warm-season grasses that stay active when northern lawns go dormant.

Why do Sunbelt lawns need special nutrients?

Longer growing seasons mean grass works overtime and burns through nutrients faster. Intense heat causes standard fertilizers to volatilize before grass absorbs them. Sunbelt Nutrients uses slow-release nitrogen that stays stable in high temps, plus seaweed for heat stress tolerance. Northern formulas spike and fade. This one keeps up.

Should I water my lawn after applying Sunbelt Nutrients?

Wait 24 hours before watering. The fertilizer needs time to dry and absorb into the grass blades. If your sprinklers run automatically, skip a cycle. Light watering after 24 hours helps move nutrients into the root zone.

What is the best time of day to apply Sunbelt Nutrients?

Early morning or evening when temps are below 85°F. Avoid midday heat. The fertilizer absorbs better when grass isn't stressed by sun, and you reduce evaporation. If you must apply during warm weather, water the lawn the day before.

How long after Sunbelt Nutrients can I apply my next fertilizer?

Wait 4-6 weeks between liquid applications. If you're switching to a different product like Active Lawn or Southeast Nutrients, the same timing applies. Stacking fertilizers too close together risks burning your lawn.

What will Sunbelt Nutrients do for my soil?

The seaweed extract supports root strength and heat tolerance, which helps grass pull nutrients more efficiently from soil. The potassium improves water management in the root zone. It's feeding the grass and supporting the soil biology that keeps roots healthy.

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.
