April on the Mullica side of Little Egg Harbor sounds like red-winged blackbirds arguing over the reeds, and Mystic Island lawns come out of winter pale and salt-burned. Hahns LandScaping starts them over — raking out dead thatch, clearing beds of broken phragmite stalks, taking the first cut before the ground firms up for good. Mowing settles into a weekly rhythm from there, with trimming and edging every visit so nothing creeps over a walk. Spring cleanups are the difference between a yard that recovers and one that simply sits there. By June that difference is visible from the street.
