Above Lake Valhalla the ridge turns first — sumac, then maple, then the long gold of oak — and the lawns below hold their green a little longer for it. Artisan Landscapes and Pools works those slopes and level yards across Montville, mowing, edging and trimming through the growing months and clearing the beds once the leaves let go. There is a plain satisfaction in a lawn cut clean to its border while the lake goes pewter under an October wind. Come winter the same driveways get plowed and the walks shoveled, the salt down before anyone reaches for a car door. Montville asks for both kinds of attention, and both are worth doing well.
