- Balanced nutrients plus 2% sulfur to unlock your soil

- Works on all lawn and grass types

Ingredients
Sulfur (2%) helps correct high pH soil and improves your lawn's ability to absorb the nutrients already in the ground. Think of it as unlocking what's been stuck.
Iron drives that deep, rich green color you notice on the healthiest lawns in the neighborhood.
Sugar beet extract helps your grass handle heat, drought, and everyday wear so it bounces back stronger.
How to use
Apply early morning or evening when your lawn is hydrated. Avoid applying to drought or heat-stressed lawns.
- Connect the sprayer to your hose and attach the fertilizer pouch.
- Apply across your lawn until the pouch is empty, about 10 to 15 minutes per pouch. You can get back on the grass once it's dry.
- Reapply every 4 to 6 weeks from spring through fall. Keep the sprayer for future use.

Seemed to help thicken some areas of my yard that needed a boost before the fall feed. It wasn't a miracle product but did a decent enough job.
Was this review helpful?Good, easy to use.
Good. Easy to use. made my lawn happy. we hit a really hot patch of the summer so might not have popped as much as desired but think more due to the weather.
Was this review helpful?Good stuff!
Brightened up grass and promoted growth during very hot months. Good stuff!
Was this review helpful?Very pleased
Was happy with the ease of use and how to use of this. No special tools required and a nice turn around from brown to green. Will buy again.
Was this review helpful?Works great
We have had a hard time keeping grass in our backyard without resorting to chemical fertilizers, which we don't want to use. Every summer the grass turns brown and the weeds take over and we lose more grass. This year I reseeded a small patch of our lawn with a mix of grass and clover and used Sunday organic fertilizer on it. Now we have a small patch of lush, green grass/clover and hope for the future of our lawn.

Questions & answers
2 questions
Question: At what temperature can I use this product?
Louisa D.
Optimal temperatures are between 50F to 85F for the fertilizer to be most effective.
Question: Do I use this on a dry or wet lawn? Also, can it prior to rain or watering?
Louisa D.
We suggest waiting until rain is not in the forecast for 24 hours. You'll want to give the nutrients enough time to absorb before the rain hits.
