A Berkshire summer is short and it wastes nothing — by July the fields around the Hinsdale Flats are shoulder-high and the lawns near Ashmere Lake are growing faster than anybody expects. Quails Landscaping keeps pace with that surge: mowing on a dependable week, trimming out around stone walls and lake stairs, beds edged and mulched, clippings and brush carried away. Up where the east branch of the Housatonic begins, the ground stays cool and damp and the grass answers well to a sharp blade. Cleanups pull the winter's sand and broken limbs out of the yard once the drifts finally give up, and take the leaves off before the ground locks. In a place with this few green weeks, none of them should be spent looking rough.
