Early fall is one of the best times to test your soil. A soil test can tell you if your lawn or garden needs critical nutrients and how much. This way, your plants and your wallet will stay healthy. You won’t waste your money applying fertilizer or lime that your plants don’t need.

Having healthy soil in your garden results in healthy plants. Whether you’re planting vegetables, flowers, grass, trees, shrubs, or anything in between, a soil sample is the first thing to check off the list. Gathering a soil sample from your landscape and having it tested by MSU Extension’s Soil Testing Lab should be the initial step in any gardening adventure. Plus, it’s pretty easy to do!
