Resilient Summer Moisture
Lawns here endured 12 weeks of drought over the last year, but the county is currently free of any drought designations. This lack of current moisture stress provides a great opportunity to strengthen root systems.
Growing Window and Grass Types
Kentucky Bluegrass thrives in this climate, especially when planted within the window between the May 22 and September 30 frosts. The well-drained soil makes late summer an excellent time for successful sodding.
