A May rain in Hastings can turn the air to glass — everything close and humid and impossibly green, the ground along Fish Hatchery Park soft underfoot. Terrarium Lawn Care lives for that stretch, when turf grows an inch between visits and a well-timed cut sets the tone for the entire summer. The service is simple and steady: mowing on schedule, trimming the tight spots, edging the walks, then leaving the drive swept so the only evidence is even green and a straight line. Watching a lawn come back thick after a wet spring is one of the better things about working outdoors in Michigan. Hastings, Middleville and Delton are all within reach.
