April at Rensselaer Lake, out by the old Six Mile Waterworks, is all mud, meltwater and the first honest green of the year. Eldi Landscaping Services LLC starts its Albany season right about then, spring cleanup first to haul off what the winter piled up, then the mowing rhythm once the ground firms. Trimming and edging keep a yard's outline sharp while the growth is at its wildest. By fall the same hands are back for the leaves, closing the year the way it opened. A season well kept is mostly a matter of arriving on time, again and again.
