This far north the growing season is short and it knows it — Colebrook greens up late, then rushes, with the Connecticut River bright on one side and Monadnock Mountain standing over the Vermont bank on the other. Dauphinais Mowing/Landscaping works fast through that window, mowing and trimming while the grass is running, edging walks, mulching beds and shaping hedges before the light starts pulling back in August. Spring cleanup here means clearing a hard winter's worth of sand and broken limbs; fall cleanup comes early, with leaves down before some towns have started. There is something satisfying about a level, trimmed lawn in the middle of the Great North Woods — a made space inside all that forest. Short summer, full use of it.
