Montgomery County's Favorable Lawn Outlook
Montgomery County earns a lawn difficulty score of 49.2, making it the easiest county in this group to maintain and nearly matching the national median. This Zone 7b region is slightly more favorable for lawns than the Tennessee state average.
Ideal Rainfall and Summer Growth
Annual precipitation of 51.3 inches is very close to the ideal range of 30-50 inches for healthy turf. While there are 50 extreme heat days, the 4,550 growing degree days provide a consistent and manageable growing season.
Quality Silt Loam with Better Balance
The soil features a pH of 5.80, which is closer to the ideal 6.0-7.0 range than many neighboring counties. This moderately well-drained silt loam provides a solid foundation, though minor lime additions may still be beneficial.
Handling Abnormal Dryness with Ease
The county spent 19 weeks in drought over the last year, and currently, all areas are considered abnormally dry. Because no part of the county is in severe drought, moderate irrigation should be enough to keep lawns green.
Seize the Growing Season Early
With a last spring frost of April 6, you can get an early start on your lawn projects this year. Plan to have your lawn established and healthy before the first frost of autumn arrives on October 30.
