In April the understory at Mountain Lakes Preserve fills with dogwood, white against bare gray trunks, and Princeton's yards start asking for attention all at once. Dogwood Lawn Care takes that first rush in order: the spring cleanup, the opening cut, the borders cut back along walks and beds after a winter of settling. Grass here runs hard through a wet May and wants a steady hand more than a heavy one. From there it is mowing and trimming on a rhythm the lawn can actually keep. Princeton, Hopewell, Pennington, Skillman and Kingston are all within reach.
