A year-round fertilization plan for Fescue lawns in Zone 7a. Adjust based on your lawn's condition and soil test results.
Early Spring (March–April)
Timing depends on whether you grow Fescue — warm-season types green up later.
Late Spring (May)
Knoxville's transition zone means your grass is actively growing now regardless of type.
Early Fall (September)
The most important feeding in Knoxville. Cool-season grasses peak now; warm-season types store energy.
Late Fall (November)
Final feeding before Knoxville's first frost. Builds root strength for winter.
The most common mistake Knoxville homeowners make is fertilizing at the wrong time. In Knoxville's transition zone, the timing depends on whether you have warm-season or cool-season grass. Fescue does best with the schedule above.
Before you buy fertilizer, know your lawn size. The average Knoxville lot is 10,800 square feet, but that includes your house, driveway, and patio. Use LotSite to measure just the grass area — then plug that number into our fertilizer calculator to get the exact bags you need.
For a 10,800-square-foot lot in Knoxville, you'll typically need 2–4 bags of fertilizer per application depending on the product. Over-fertilizing wastes money and can burn your lawn — measuring accurately saves both.
