  • Molasses: Supports soil microbial activity
  • Iron: For deep, rich green color in your lawn

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.

Beautiful backyard!

First year with Sunday Lawn. I started with them in August I believe? I am a widow who loves my backyard, 2 dogs and cat, and wanted a non- chemical lawn. This product really feeds and nourishes my lawn! I water on a schedule which is important too. I used to use Trugreen but decided to do it myself...

Finally!!!

It is an immense relief to find a yard care option that works with nature not against it. No more green short term facade, with poisoning long term destruction. And it's actually fairly affordable?!?!?! Wow. Mindblown. Thank you very much.

Plan is great. Customer support us even better

I started with a weed infested lawn. I had tons of questions and the guys were more than helpful with their responses. Will even went as far as making video responses to a video I sent showing my lawn's status. Super happy with the service.

Finally Making Some Progress with my Yard!!

This is my first year using the Sunday System. I have unsuccessfully tried the DIY yard treatment granules from the big box stores and tried hiring a truly green service to apply for me, but no success with either. From the pictures, you can see that for the first time in ten years, I am finally mak...

Such an easy to follow system!

I love that the products just show up, I don't have to mark dates on my calendar or research what I'm supposed to be doing now. Getting the emails telling me which product to use now; and having Sunny to ask questions has been a game changer. I have been following the plan for about 6 months now and...
