Data Story
About Lawn Care in Haines Borough, Alaska
Easy Growing in the Haines Panhandle
Haines Borough boasts a lawn difficulty score of 61.5, making it significantly easier to maintain a lawn here than in the average American county. This score also beats the Alaska state average of 57.8, thanks to a relatively mild coastal climate.
Ideal Rainfall for Coastal Turf
The borough receives 52.9 inches of annual precipitation, which is perfectly positioned near the ideal range of 30-50 inches. Your growing season is generous for Alaska, starting with the last frost on April 30 and extending through October 7.
Coastal Soil Preparation Needs
Specific soil texture data is unavailable, so localized testing is essential to check for the ideal pH range of 6.0-7.0. Given the 52.9 inches of rain, ensuring your lawn has a well-draining foundation is the most critical prep step.
Zero Drought Weeks This Year
Haines remains exceptionally resilient to drought, with zero weeks in drought conditions over the last year. With no abnormally dry areas currently reported, you can rely mostly on natural rainfall to keep your grass green.
Maximizing the Haines Growing Season
Take advantage of the April 30 frost date by seeding early with cool-season perennials like Perennial Ryegrass. The 761 growing degree days provide ample energy for a lush lawn before the first frost in early October.
