Just before six on an August morning, Manasquan sounds like a hundred small sprinklers ticking over lawns that have to make it through another shore summer. JCS LAWN SPRINKLERS LLC works that side of lawn care: irrigation heads set and adjusted so the water lands on grass instead of the sidewalk, zones tuned for sandy soil that drains nearly as fast as you fill it, systems opened in spring and blown out ahead of the first hard freeze. Around the irrigation comes the ordinary, necessary upkeep of a lawn, with mowing, trimming, edging and beds kept tidy. A yard still green in the last week of August is not luck. Serving Manasquan and the nearby towns of Monmouth and northern Ocean County.
