The first genuinely warm Saturday in May puts all of Elmwood Park outdoors at once — hoses uncoiled, doors propped, half the borough deciding the yard has waited long enough. SRVLANDSCAPING CONSTRUCCIÓN & DESIGN LLC has usually been at it for weeks by then, working through spring cleanups, first cuts, fresh mulch and beds cut back into shape. From there it settles into a rotation of mowing, edging, trimming and hedge work that runs until the leaves come down and get carried off. Yards packed this close together share a mood. A good one is contagious all the way down the block.
