Lawn Care Basics

Lawn Inspection

• Test your lawn: The best way to know your soil’s true condition is to test it. Many do-it-yourself kits are available at local garden suppliers, usually for less than $20, and give you results right away. Unfortunately, their results aren’t very complete, and they rarely give specific recommendations for improving the soil.
• Consult a professional lab: Professional labs are listed in your local phone book. These labs offer much more information than DIY kits. But lab consultations can also cost more, depending on the types of tests the lab conducts. The lab will usually want you to collect the soil in a specific way, so contact them before you take any samples.
• Consult your local USDA cooperative extension agent: Phone numbers for local U.S. Department of Agriculture cooperative extension offices are usually listed in a phone book’s county government section. Their soil tests generally cost between $10 and $30, depending on what you want tested. Typically, an extension office can also make soil improvement recommendations for you.

How to Take a Soil Sample

1. Take small soil samples from 7–8 different areas on the lawn. Use a clean trowel and dig down about 6".
    
   
2. Mix all the samples in a clean container. Then let the soil dry overnight and pack it in a clean plastic bag or bottle.
    
   
3. Test the soil with a DIY kit, send it to a lab, or drop it off at your local extension service office to find out its pH and mineral makeup.
