Andover soil is the glacier's leavings — stone, sand and a thin skin of loam — with Kearsarge standing off on the horizon watching how it turns out. Merzi Excavation LLC works with that ground instead of arguing with it, mowing the turf that has taken hold, feeding it, mulching the beds, cutting a clean line where lawn stops and gravel starts. Grass here earns every inch it gets, which makes a full green yard something genuinely worth standing back to look at. The season opens with a cleanup and closes with one, and the middle is steady weekly attention. Patient work, on ground that demands patience.
