Healthy soil is important for healthy plants, so find out what your soil needs.
Feed the soil and the plants will have everything they need. But what should you feed the soil in your garden? There's only one way to know: get a soil test. Here is a list of soil test labs in most states and Canadian provinces. The technicians at the lab will tell you exactly what to do to set up the test and read the results, often in collaboration with the cooperative extension agent in your area.
