About Lawn Care in Pulaski County, Indiana
Challenging Conditions in Northern Indiana
With a lawn difficulty score of 56.3, Pulaski County is one of the tougher places in Indiana to maintain a perfect yard. While it still beats the national median of 50.0, it sits far below the Indiana average score of 71.0 due to its harsh Zone 5b winters.
Colder Winters and Moderate Rainfall
Pulaski receives 39.3 inches of rain annually, which is slightly below the state average of 44.2 inches. With only 13 extreme heat days and 3,081 growing degree days, the primary challenge is the shorter growing window rather than intense summer heat.
High Acidity and Sandy Soil
The soil pH is notably low at 5.15, which is far below the ideal range for turf and likely requires lime amendments. With sand making up 49% of the soil profile, water and nutrients leach away quickly, requiring more frequent attention than heavier Indiana clays.
A Year of Sustained Dryness
The county has faced 39 weeks in drought over the last year, and currently, 100% of the area remains abnormally dry. This prolonged water stress, combined with sandy soil, makes consistent irrigation essential for lawn survival.
Sowing for Zone 5b Success
Kentucky Bluegrass and Fine Fescue are the best bets for these northern Indiana temperatures. Wait until the threat of frost passes after April 26 to begin seeding, as the growing season wraps up quickly with an October 18 fall frost.

Seasonal Lawn Care Checklist
Spring
- Apply pre-emergent herbicide when soil reaches 55F
- Overseed bare spots once frost risk passes
- Start irrigation if rainfall is below 1 inch/week
- 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
Winter
- Avoid walking on frozen turf
- Service mower and sharpen blades
- Plan spring soil amendments based on fall test
- Keep lawn clear of debris
