When Should I Do A Soil-Test?
Here in Cobb people often call or come into the office with questions regarding problems with their grass, trees, gardens, and other plants. For us to provide the most accurate information, we will typically ask if a soil-test has been done. Plants are living organisms and will sometimes get sick, or unhealthy just like us. Like having our vitals taken when we go to the doctor, the soil test results give us a base line of accurate information to help with our prognosis and suggestions.
If you are pre-planning an area for things like sod, trees, vegetables, or ornamentals, it is important to do a soil-test as early as possible. Depending on the results some amendments such as lime could take several months to affect the soil. The basic soil test in Cobb County is $9.00 and will provide the soil pH, primary nutrient content, and personalized recommendations to amend the soil based on the selected crop.
