January at Spot Pond: pines holding their load, the Fellsway swept down to wet black, and every side street off it waiting its turn. Evergreen Tree & Landscaping Company plows and shovels the driveways on those streets, clears walkways to the door, and treats the ice that forms at the bottom of a slope. When the thaw finally holds, the same properties get mowing, string trimming, crisp bed edges and cleanups that carry the winter's debris off the turf. The two seasons ask for opposite things — patience in the green months, speed at two in the morning in a storm. Both get done, on the same Medford streets.
