By mid-October the oaks along Callahan State Park have made their decision, and every lawn between there and town is under an inch of red and brown. Ferre Landscaping and Exterior Management clears it — blowing, raking and hauling until the grass can see the sky again before the ground locks up. The rest of the year is the steady part: mowing on schedule, trimming tight around trees and posts, edging walks, mulching beds in spring. Framingham lawns are asked to do a lot, sitting as they do between woods and pavement. Keeping them even and green is a quiet pleasure, week after week.
