Northern Challenges in LaGrange County

Lower Precipitation and Cool Temperatures
Annual precipitation of 38.5 inches is below the state average of 44.2, meaning supplemental watering is often required. The county stays relatively cool with only 11 extreme heat days, which helps prevent grass from going dormant in mid-summer.
Correcting Highly Acidic Sandy Soil
The soil pH here is quite low at 5.40, which can lock out essential nutrients from your turf. With a sand content of 54.2%, adding organic matter is critical to improve water retention and stabilize the soil structure.
Managing High Sand During Dryness
LaGrange County faced 16 weeks of drought in the past year, and 55% of the area remains abnormally dry. Use mulch-mowing to return clippings to the lawn, which helps the sandy soil retain whatever moisture it can.
Seeding for Success in the North
Wait for the last spring frost on April 26 before starting new seed, and choose cold-hardy varieties like Kentucky Bluegrass. The first fall frost arrives early on October 21, so complete all major lawn renovations by early September.
