Managing Sandy, Acidic Ground
A soil pH of 5.39 means your lawn is more acidic than the ideal 6.0 to 7.0 range. With a composition of 54.7% sand and 9.6% clay, your soil drains quickly but may struggle to hold onto nutrients. Regular soil testing and lime treatments are necessary to prevent your lawn from becoming patchy or yellow.
Current Dry Trends Require Attention
While the county had 19 weeks of drought last year, 98.2% of the area is currently classified as abnormally dry. This current dry spell can stress your lawn despite the high historical rainfall averages. Prioritize watering deeply twice a week to ensure moisture reaches the roots through the sandy soil.
Plan Around a May Start
Kentucky Bluegrass blends work well here, provided you manage the soil acidity. Your primary growing season runs from the last spring frost on May 2nd to the first fall frost on October 13th. Early autumn is the best time for overseeding, allowing the grass to take advantage of the county's high rainfall.
