By late September the light over Caribou goes thin and clear, the potato harvest is on, and lawns settle into their last good weeks of growth. VETSEEDCO works that window and the whole green season around it — mowing, trimming, edging, and clearing a yard down to bare turf before the ground hardens. Grass this far north does its best growing in the cool ends of the year, so timing matters as much as effort. There is something worth standing back to look at in a lawn that comes out of a short summer thick and even. Yards around town get that attention week by week, from mud season to hard frost.
