• Mix samples together: Combine everything in the bag for a representative result that reflects your whole lawn
• Results arrive in 2 to 4 weeks: You'll get an email with your full lawn soil analysis breakdown, then use it to guide your lawn fertilizer plan

Lawn soil test kit FAQs

What does the Sunday Soil Test Kit measure?

The kit measures 15 essential metrics that affect how well your lawn grows. That includes macronutrients like nitrogen, phosphorus, and potassium, plus micronutrients, pH levels, organic matter content, and cation exchange capacity. Together, these give you a complete picture of your soil's ability to support healthy grass and strong roots.

How do I collect and send my lawn soil sample?

Use the included soil coring tool to pull samples from 3 to 6 spots around your yard, each about 4 to 6 inches deep. Mix the samples together in the provided bag, attach the ID sticker, and drop it in the mail with the prepaid shipping label. The whole process takes about 15 minutes.

How long does it take to get lawn soil test results?

Results typically arrive in 2 to 4 weeks via email. Your report breaks down each metric with clear explanations, so you'll understand what your lawn needs without wading through confusing charts.

How will a lawn soil test kit help me choose the right fertilizer?

When you know exactly what nutrients your soil already has, you can choose products that fill the gaps rather than adding more of what's already there. This targeted approach, based on your lawn soil analysis, helps you avoid over-fertilizing and gives your grass seed and fertilizer the best chance to perform.

Do I need to test soil from different areas of my lawn separately?

For most yards, mixing samples from multiple areas gives you a reliable average. But if one section looks noticeably different (struggling grass, heavy shade, or drainage issues), testing that area separately can help you pinpoint specific problems and treat them more effectively.
