Middle Range Pond warms slowly, and Poland's gardens follow it — very little stirs until the middle of May, and then everything at once. The Dirt Store works that surge as a lawn-care outfit: loam and mulch spread, beds shaped and edged, seed laid into thin ground, mowing and trimming on a weekly turn, cleanups at the front and back of the year. There is real pleasure in good soil going down over a tired lawn and in the deep green that answers a month later. Every property here sits on its own mix of sand, ledge and clay, and the ground tells you plainly what it wants. Poland, Minot, Mechanic Falls, New Gloucester, Oxford and Auburn.
