Data Story
About Lawn Care in Bristol County, Massachusetts
Bristol Leads the State in Lawn Ease
With a high lawn difficulty score of 69.3, Bristol County is the easiest place in our list to maintain a beautiful lawn. This score is significantly higher than both the state average of 56.8 and the national median of 50.0. The Zone 7a climate provides a long, productive window for turf management.
Abundant Water and Ample Warmth
Bristol receives 49.4 inches of annual precipitation, which is at the upper limit of ideal lawn watering needs. The county sees 2,833 growing degree days and 11 extreme heat days, indicating a vigorous growing season. These factors lead to fast-growing grass that may require more frequent mowing than inland counties.
Foundation Built on Local Care
While specific regional soil pH and texture data are limited for Bristol, the high precipitation suggests a risk of nutrient leaching. Homeowners should perform a local soil test to determine if they need to balance acidity. Proper aeration is often the key to ensuring the 49.4 inches of rain reaches the root zone effectively.
Navigating Current Dry Spells
The county has faced 11 weeks of drought over the last year, and the entire county is currently listed as abnormally dry. Even with high annual rainfall, short-term dry periods can stress turf quickly. Focused watering during the 11 extreme heat days will help prevent lawn dormancy.
Lush Lawns for the South Coast
The mild 7a climate is perfect for a blend of Kentucky Bluegrass and Tall Fescue for durability. Seeding is most successful after the April 27 spring frost date when soil temperatures rise. You have a long window for maintenance before the first fall frost on October 15.

- 3EstablishSep 17 – Oct 14
Protect young seedlings: mow only after they reach ~3 inches and hold off on weed pre-emergents until established.
Keep the seedbed consistently moist — roughly ¼ inch of water daily, split into shorter cycles if the surface dries out quickly. County-specific soil texture isn’t available here, so adjust to how fast your own soil drains.
You’re in the transition zone — both cool- and warm-season grasses can work; the schedule above follows the species you selected.
Seasonal Lawn Care Checklist

- Apply pre-emergent herbicide when soil reaches 55F
- Begin mowing when grass reaches 3 inches
- 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
- Overseed warm-season lawns if thinning
- Apply fall fertilizer (highest N application for cool-season)
- Continue mowing until growth stops
- Rake or mulch leaves to prevent smothering
Winter
- Apply pre-emergent for winter weeds
