Before diving into the best times to fertilize, it's essential to understand the type of grass that makes up your lawn. In Nashville, homeowners typically have either cool-season grasses or warm-season grasses. Each type has different growth patterns and, therefore, different fertilization needs.

For those with cool-season grasses, the best times to fertilize your lawn in Nashville are in the early spring and early fall.
- Early Spring (March to April): As temperatures begin to warm up, cool-season grasses start to come out of winter dormancy. Fertilizing in early spring helps to promote healthy growth as the grass begins to green up. Use a balanced fertilizer with a higher nitrogen content to encourage lush growth.
- Early Fall (September to October): Fall is an ideal time to fertilize cool-season grasses because they experience a surge in growth as temperatures cool down. Fertilizing during this period helps strengthen the grass’s roots, preparing it for the winter months. A slow-release fertilizer works best during this time, providing nutrients gradually over the season.
Best Times to Fertilize Warm-Season Grasses
For warm-season grasses, fertilization should be timed to coincide with their peak growing period in the summer.

Fertilizing during these months can lead to excessive growth that is not sustainable during the colder weather, potentially causing damage to the lawn. Additionally, applying fertilizer during dormancy periods can result in wasted nutrients, as the grass will not effectively utilize them.
Soil Testing: A Key Step Before Fertilizing
Before applying any fertilizer, conducting a soil test is highly recommended. A soil test will determine the pH level of your soil and identify any nutrient deficiencies. This information will guide you in choosing the right type of fertilizer and applying it at the correct rate. In Nashville, soil tests can be conducted through the University of Tennessee Extension or local garden centers.
Choosing the Right Fertilizer
Fertilizers come in various formulations, and choosing the right one depends on your lawn’s specific needs. The three primary nutrients in fertilizers are nitrogen (N), phosphorus (P), and potassium (K). The ratio of these nutrients is indicated on the fertilizer packaging, such as 10-10-10 or 20-5-10.
- Nitrogen (N): Promotes lush, green growth and is the most important nutrient for most lawns.
- Phosphorus (P): Supports root development and is essential for young or newly seeded lawns.
- Potassium (K): Helps with overall lawn health, disease resistance, and drought tolerance.
For most lawns in Nashville, a balanced fertilizer with a higher nitrogen content will be suitable, but the specific ratio should be determined based on your soil test results.

- Use a Spreader: A broadcast or drop spreader will help distribute the fertilizer evenly across your lawn. Make sure to calibrate the spreader according to the fertilizer’s instructions.
- Watering After Application: After applying fertilizer, water your lawn thoroughly to help the nutrients soak into the soil. This also prevents the fertilizer from burning the grass blades.
- Avoid Overlapping: When applying fertilizer, be careful not to overlap passes with the spreader, as this can lead to uneven application and potential lawn damage.
