South of the borough the Great Swamp lies low and wet, and on spring mornings its mist drifts up into Florham Park's back yards before the sun sorts it out. Lendechy Landscaping & Construction LLC starts the season in that damp air — the first passes of April, matted leaves pulled out of the low corners, borders cut back where turf has crept onto the drive. From there the summer settles into rhythm: mow, trim, tidy, return. Ground near the Passaic's headwaters holds water longer than most, so timing a cut matters as much as making it. By the time the light goes gold in the evening, the lawns along these streets should read as an even, unhurried green from hedge to hedge.
