Data Story
About Lawn Care in Newton County, Indiana
Colder Winters Define Newton County
Newton County is in hardiness zone 5b, making it the coldest region in this group with a lawn score of 70.6. This score is right in line with the Indiana state average of 71.0, though the winter survival of grass is a greater concern here.
High Heat Days Despite Cold Zone
Even in a colder zone, Newton faces 23 extreme heat days, which is higher than the state average of 20. The 40.1 inches of precipitation is on the lower end of the ideal range, necessitating careful water management during summer.
Sandy Soils with Poor Drainage
With 53.0% sand, these soils would typically drain fast, but the 'very poorly drained' classification suggests a high water table or underlying clay. The 6.23 pH is excellent, but the unique texture requires aeration to prevent root rot in wet years.
Extended Drought Impact
Newton County has endured 32 weeks of drought over the past year, and 10.5% of the area remains in severe drought (D2+). With 90.7% of the county classified as abnormally dry, supplemental irrigation is currently vital.
Cold-Hardy Varieties Are Essential
In zone 5b, choosing winter-hardy seeds like Creeping Red Fescue or Kentucky bluegrass is critical for survival. Planting should occur between the April 23 spring frost and the October 14 fall frost for best results.

- Soil test every 2-3 years — adjust lime or sulfur as needed
Summer
- Mow at recommended height weekly
- Water deeply 1-2 times per week (1 inch total)
- Avoid fertilizing cool-season grasses in peak heat
- Scout for grubs and treat if >10 per sq ft
Fall
- Core aerate compacted areas
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
