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

    Product features:

    • 0-0-20 NPK (nitrogen-phosphorus-potassium) liquid lawn fertilizer
    • Premium fertilizer — concentrated nutrients and speciality ingredients
    • Addresses potassium deficiencies in soil
    • Supports soil health, stress resilience, and water management

    • 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:

    • Potassium: Addresses soil deficiency, and supports grass health, water management and stress resilience
    • Seaweed: For greening and stress resilience

    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 hints from Lawn Advisors:

    What does potassium do for my lawn?

    Potassium in soils is critical for healthy grass growth and function. It helps grass stand upright by enhancing plant turgor, improves stress tolerance, and aids in the efficient regulation of water within plants.

    Why is my soil deficient in potassium?

    Potassium is a soluble nutrient that can easily leach out of well-drained soils. Soils that are sandy or located in coastal regions with frequent rain are particularly prone to potassium deficiency due to this leaching process.

    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 boost pouches alongside other Sunday fertilizers

    Boosts with nutrients 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!
