At a pH of 5.74, Morgan County's soil is more acidic than the ideal 6.0-7.0 range for lawns. The soil contains roughly 21.2% clay and 21.6% sand, necessitating regular aeration to prevent compaction. Adding lime can help neutralize the acidity and unlock essential nutrients for your grass.
Moderate Dry Spells Affect One-Quarter of Land
While the county had only 4 weeks of drought last year, currently about 24.9% of the area is considered abnormally dry. These conditions require localized attention to prevent brown patches from forming in sun-exposed spots. Mulching grass clippings back into the lawn helps retain soil moisture during these dry intervals.
