Soil Testing and Fertilization Guide For Tennessee Lawns
- December 21, 2020
Winter is here in Tennessee which means it’s time to prepare our lawns for winter. One of the things that we can do to get our lawn looking great and prepared for next spring is to fertilize. Fertilizing in the winter encourages vigorous root growth in your plants. This is essential for your plants to make it through the winter and green up in the spring. Deep roots help your plants withstand drought conditions and store food which is needed for spring green-up.
First, to get the most out of your fertilizer, you will want to get a soil test. A soil test can tell you exactly what nutrients are in your soil or if it is too acidic or alkaline. Knowing this can help you determine which fertilizer to use and which plants will grow best in your soil. Here in Tennessee, our soils tend to be too acidic for optimum crop production. So getting a soil test should be the first step in developing a sound fertilization program.
Soil acidity is the level of acids present in the soil. When acid levels increase, the pH of the soil decreases. The pH scale ranges from 0-14. Soils in Tennessee range from 4.5 to 7.5. Soils with pH values greater than 7.0 are considered alkaline or sweet, and those with values of less than 7.0 are acid or sour.
When pH falls below 7.0 it is considered acidic. Acidity can increase as magnesium, calcium, and potassium are replaced by hydrogen via erosion, farming, and leaching.
When soils are too acidic it prevents basic nutrients like phosphorus and potassium from being taken up by the roots. Trying to fertilize acidic soils is useless as the plants are unable to use the nutrients. Soil acidity can be corrected with the addition of lime.
Applying lime to acidic soils provides the following benefits:
You can apply lime to your soil any time of the year but fall and winter are ideal as lime supplies are in stock. This is because most farmers apply lime in the spring and finding some could be difficult. Spread lime evenly and uniformly across your yard with a spreader. Applying lime unevenly can result in growing problems for several seasons.
With winter here it’s time to start thinking about next year’s lawn care goals. At 4Ever Green, we offer weed control and fertilization packages as well as aeration and overseeding services to enhance the health and look of your yard and get it ready for spring.
