A Sunday premium selection

Premium fertilizers, enriched with potent nutrients and unique soil enhancers, outperform standard options to deliver superior, long-lasting lawn health.

Product features:

  • 15-0-4 NPK (nitrogen-phosphorus-potassium) liquid lawn fertilizer
  • Premium fertilizer — concentrated nutrients and specialty ingredients
  • Addresses potassium deficiencies in soil
  • Supports plant turgor, stress resilience, soil health and water management
  • Made for all lawns and grass types
  • Formulated without pesticides
  • User-friendly hose-on application
  • Covers up to 3,000 sq. ft.
  • Includes liquid fertilizer in flexible reduced plastic packaging and a custom-engineered universal hose-end sprayer

Ingredients:

  • Sulfur: Addresses deficiencies, high pH and improves nutrient absorption
  • Iron: For deep greening
  • Sugar beet extract: For stress management

Instructions:

For best results, apply early morning or evening, and make sure your lawn is adequately hydrated. Avoid use on drought-affected or heat-stressed lawns.

  1. Connect the universal sprayer to your hose and the fertilizer pouch. This sprayer is designed for the optimal mix of water and nutrients.
  2. Apply the fertilizer across your lawn until the pouch is empty, which should take about 10-15 minutes. Once the fertilizer dries, you can get back out on your grass.
  3. Reapply every 4-6 weeks spring through fall. Keep the sprayer for future applications.

Helpful Tips from Lawn Advisors:

What does sulfur do for my lawn?

Sulfur, like in our Super S blend, enhances nutrient uptake in your soil and addresses deficiencies, improving overall lawn health. The benefits range from richer color and increased stress resistance to consistent, robust growth.

Why is my soil deficient in sulfur?

Sandy or well-drained soils can lose sulfur due to leaching, cleaner air regulations result in less sulfur deposits from rain, and removing grass clippings can deplete sulfur. Together, these factors can lead to a sulfur-deficient lawn.

How are Sunday premium liquid fertilizers different?

Sunday's premium liquid fertilizers, once exclusive to custom lawn plans, are highly concentrated with nutrients, soil amendments, and specialty ingredients for effective and fast results.

How to apply alongside other Sunday fertilizers

Boosts can be used in combination with your Sunday Lawn Plans or other fertilizers. For best results, follow the instructions below.

  • For liquid fertilizer: First, apply the boost pouch, then wait 7 to 10 days before applying the liquid fertilizer.
  • For granular: Apply boost pouch, wait 4-6 weeks, then apply granular fertilizer.

When is it safe for people and pets to go on my lawn after applying?

Our ingredients break down quickly and don’t persist in the environment. After our products dry, you can get back to using your lawn!

Are there any US states where this is not approved for use?

Super S is restricted in Idaho & Oregon.
