Cool temperature in the fall encourages new growth. Cool-weather turf grasses such as fescue thrive and produce lush lawns when given proper care in the fall. Part of your routine lawn maintenance should include fertilization, and sowing seeds to repair damaged areas and establish a new lawn. Most soils are slightly acidic and need an application of lime in the fall to bring the soil pH closer to neutral. Soil testing will indicate the pH of the soil. Applying lime in the fall gives time for it to completely disperse into the soil.
Take a small sample of soil from various spots in your lawn using the soil probe. Mix the samples together and place a small amount in the soil test kit. This will give you an aggregate average pH of the whole yard. The pH level should be between 6.5 and 7.5. If your pH reading is over 7.5, do not add lime to your lawn.
Purchase granular dolomite lime. Lime is available in 50-lb. bags at your local garden center. You will need 50 lb. of lime for every 1,000 square feet of lawn.
Add lime to the seed spreader. Walk slowly, pushing the seed spreader to cover the lawn evenly. To raise the pH level in increments of .5, use 15 lb. of lime per 1,000 square feet of lawn.
Test the soil again 4 weeks after the initial application. If the pH is still below 6.5, you will need another light application of lime.
