Phillips Brook runs cold under the road on the Ashby side of Ashburnham, and the yards along there hold their dew until mid-morning. Streamline Fence & Landscaping mows, edges and trims through those roads once the ground firms up in May. Damp ground asks for timing — cutting when the turf can carry a machine, keeping lines straight where a yard tilts toward the water. Spring brings cleanups and the first pass of the year; November brings leaves, and there is never a small amount of them. A straight edge run the full length of a fence line is the sort of detail people notice without quite knowing why.
