About Lawn Care in Lawrence County, Indiana
Favorable Growing in Southern Indiana
Lawrence County boasts a lawn difficulty score of 75.3, outperforming the state average of 71.0. Situated in Hardiness Zone 6b, the county benefits from a longer growing season that allows for more established root systems.
Abundant Rainfall Fuels Growth
With 48.5 inches of annual precipitation, Lawrence County is one of the wettest in the state, nearing the high end of the ideal range. This moisture supports 3,585 growing degree days, though only 15 extreme heat days keep evaporation in check.
Silt Loam Needs Drainage Support
The pH of 5.84 is slightly low but workable for most lawn types. However, the silt loam soil is poorly drained, so homeowners should monitor for runoff and avoid mowing when the ground is heavily saturated.
Current Dryness vs Annual Rainfall
While the county had only four weeks of drought last year, 100% of the area is currently classified as abnormally dry. This recent shift means you should temporarily increase watering to protect your lawn's health despite the high annual rainfall totals.
Maximize a Longer Southern Season
Take advantage of a long season that runs from April 20 to October 30. Tall Fescue is an excellent choice here as its deep roots can handle the transitions between heavy rain and the occasional dry spell.
