When to take a Sunday lawn soil test
Ideally, before your first Sunday lawn fertilizer application. This helps us better tailor your custom plan to address deficiencies and customize expert support from Sunday Yard Advisors.
If you can't sample your soil before your first fertilizer application, we recommend sampling your soil in early spring or fall.
How to complete your Sunday soil test
Collect
Use the custom-built soil coring tool to dig 4–6" below the surface, and gather a small scoop of soil from 3 or more areas around your front and backyard lawn.
Combine
Mix all of the soil samples from around your lawn together in a small bowl or pot.
For best results, be sure to remove any rocks, roots, grass or debris from the samples!
Label
Place about a cup of the combined soil sample into the sample kraft bag. Soil can be damp, but not wet.
Be sure to place the identification sticker provided onto the sample bag and seal.
Send
Place the pre-printed shipping label on the soil test shipping box and seal closed. Drop the box into the mail.

Soil test kit FAQs
Do I need to wait for my soil test results to apply my Custom Lawn Plan?
The lawn fertilizer included in your first shipment is already tailored to your lawn size, climate, and regional soil, so you don't need to wait for your soil test kit results to process to get started!
Your soil test results, if deficient, will further customize the pouches you'll receive with your future shipments.
Why start with a lawn soil test?
Every Sunday Custom Lawn Plan starts with a soil test. We use your soil data, along with satellite and local climate data, to make sure your lawn only gets the nutrients it needs when it needs them.
Sunday Tip:
Applying the wrong lawn nutrients or too much—even if they’re natural—can do more harm than good for your lawn and the environment.
The good news? Sunday soil test kits help you avoid that issue.
