Late-spring rain comes over the ridge fast here, soaks the valley in an afternoon, and leaves everything two shades greener by morning. Vida Landscaping LLC works the days that follow — mowing once the ground can take a wheel, edging walks and driveways, trimming tight to fences and posts, mulch refreshed, hedges shaped, cleanups in spring and fall. Grass in Bergen County grows hardest in the stretch between the last frost and real heat, and staying ahead of it is essentially the whole month of June. A lawn held even through that push looks effortless, which is the trick of the thing. Park Ridge and the boroughs around it are the ground where it happens.
