Your lawn's secret weapon lives underground

Super S is a 15-0-4 liquid sulfur fertilizer for lawns with high pH soil or sulfur deficiency. It combines 2% sulfur with iron for deep greening and sugar beet extract to help grass bounce back from heat and drought. Each pouch covers up to 3,000 sq ft in 10 to 15 minutes with the included hose-end sprayer. Not sure what your soil needs? Start with a Custom Lawn Plan.

What makes Super S Liquid Fertilizer (2-pack) different

  • Balanced nutrients plus 2% sulfur to unlock your soil
  • Iron for rich, deep green color fast
  • Sugar beet extract helps grass handle stress
  • Hose-end sprayer for quick, even coverage
  • Works on all lawn and grass types
  • No pesticides, just nutrients your lawn can use

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.

  1. Connect the sprayer to your hose and attach the fertilizer pouch.
  2. 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.
  3. Reapply every 4 to 6 weeks from spring through fall. Keep the sprayer for future use.

How long after seeding can I apply Super S?

Super S Liquid Fertilizer is best applied to established lawns. Wait until new grass has been mowed at least twice before applying.

Freshly seeded grass may not be strong enough to handle a full application. Give seedlings time to establish roots first.

What happens if it rains after applying Super S?

Super S Liquid Fertilizer absorbs quickly, so light rain shortly after is generally fine. A heavy downpour right after could reduce effectiveness.

Check your forecast and aim for no heavy rain for a few hours after you spray.

When is the best time of year to apply Super S?

Super S Liquid Fertilizer works best from spring through fall during active growth. Apply early morning or evening when your lawn is hydrated.

Avoid applying during peak heat or drought stress. Hydrated grass absorbs nutrients more effectively.

How often should I apply Super S?

Super S Liquid Fertilizer can be reapplied every 4 to 6 weeks from spring through fall. Each pouch covers up to 3,000 sq ft, so the 2-pack handles up to 6,000 sq ft.

Consistent use maintains soil health all season.

Can I use Super S with other Sunday fertilizers?

Super S Liquid Fertilizer works well alongside other Sunday products like Iron Boost and Potassium Boost. Space applications at least two weeks apart to avoid over-fertilizing.

A soil test can help you figure out exactly what your lawn needs so you're not guessing which products to combine.

How do I know if my lawn needs sulfur?

Super S Liquid Fertilizer targets lawns with high pH soil or sulfur deficiency. Signs include yellowing grass that won't respond to regular fertilizer and slow, thin growth.

A soil test shows your pH and nutrient levels so you can target what's missing.

    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.

    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.
