High Precipitation and Cool Mountain Air

Acidic Soils Require Careful Balancing

Ready for Spring After Mid-May
The best turf choices for this region are cold-hardy varieties like Kentucky Bluegrass or Fine Fescue. Start your growing season after the May 19 frost date, but be prepared for a slightly shorter window as the first frost often arrives by October 3.
