Haddon Lake Park runs like a green seam through Haddon Heights, and in June the low ground along it hums with insects and smells of water and mown grass. Butterfly Hill Landscaping LLC works the lawns and beds above it, mowing, trimming, edging borders to a clean line, and handling the cleanups that open the season and close it again. Plantings along the Dell want a lighter touch than the flat yards out toward the pike; that soil holds water and the shade shifts week to week. Watching a property come back across one summer, from a rough spring start to something full and even, is the whole reward of the work. Straight edges, tidy borders, and grass carrying its color right out to the fence line.
