    Exclusively available only in Sunday Lawn Plans

    This powerful formula features a blend of nitrogen for rapid growth, iron for deep greening, and seaweed and potassium for increased grass resilience. Perfect for spring and throughout the growing season, Grass Machine ensures your lawn not only grows faster but also develops a healthier, more vibrant appearance. It's the ideal solution for anyone looking to transform their lawn into a lush, green oasis.

    Consciously formulated without pesticides, Sunday champions planet-friendly solutions for your lawn's unique environmental challenges.

    Product Features:

    • 15-0-3 NPK (Nitrogen-Phosphorus-Potassium) liquid lawn fertilizer
    • Formulated to support growth, greening, and resilience in spring and throughout the growing season
    • Ideal for early-season use, and regular lawn maintenance and feeding
    • Nitrogen for growth, iron for greening, potassium, and seaweed for resilience
    • Made for all types of grass and lawns
    • Zero pesticides
    • Eco-conscious formulation for a greener, healthier lawn
    • 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:

    • Nitrogen: For strong and healthy grass growth
    • Iron: For deep greening of lawns
    • Potassium: Aids in water management and grass resilience
    • Seaweed: Supports grass resilience and greening

    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.

    How do I use with other Sunday products?

    If using other Sunday products, let liquid fertilizers dry completely before applying anything else to the lawn. For best results, use lawn fertilizer in combination with weed control and grass seed. This will help you feed properly, reduce weeds, and introduce better grasses to your lawn.

    How much should I apply based on my yard size?

    1,000–1,500 sq. ft.: 1/2 pouch

    1,500–3,000 sq. ft.: 1 pouch

    3,000–6,000 sq. ft.: 2 pouches

    How does fertilizer help my grass? How is Sunday liquid fertilizer different?

    Grass needs nutrients to thrive. Fertilizer provides these essential nutrients and enhances growth, color, and resilience. Sunday liquid fertilizers offer rapid absorption for quicker results and uniquely enrich the soil while nourishing your lawn—all without pesticides for a healthier yard.

    How much lawn fertilizer will I need?

    For each treatment: Each fertilizer pouch covers 3,000 sq. ft. for one treatment. The number of pouches you receive for each application will depend on your lawn size.

    For the growing season: We’ll take care of this for you! Follow your Sunday Custom Plan for how many times per year to apply.

    When is the best time to apply fertilizer to my lawn?

    For optimal results, fertilize your lawn when grass is actively growing. Apply early in the morning or the evening when temperatures are between 50 to 85 degrees F to a well-hydrated lawn.

    For custom lawn plan subscribers: Head over to your account’s My Plan Page to see when to apply your custom nutrient pouches.

    This product is approved for use in all states.

    Great Results

    I followed the recommended steps. After the first seeding, the ground was unreceptive so I added some topper cover/fertilizer. Aside from that, all the recommended steps have led to a beautiful lawn.

    Wonderful Lawncare

    I started using Sunday this year and I love it so far! Great products that aren't full of harmful chemicals and they work! My lawn loves the fertilizer and doesn't hate the weed killer or bug spray, both of which work really well. The soil analysis was cool to see, and so far the AI chat Sunny has...

    I’m very pleased so far

    I started Sunday treatments in August of this year and am pleased with the results. I love the ease of transactions as Sunday sends my tools as they are needed and I have a schedule that tells me when to apply. No guess work. I also love the Sunny feature and have used it a few times. It is very hel...

    Working on it

    I started the Sunday program in August. My yard hadn’t been fertilized since last autumn and isn’t in the best shape. After 4 applications of fertilizer it looks better but it isn’t where we want it. I just can’t seem to get the weeds out. I like the reminders to fertilize the lawn. I’m going to giv...

    My yard was in need of getting greener and weeds removal. Sunday excelled at the getting greener part!
