Lawns are one of earth’s most precious natural resources, harboring the world’s store of dropped contact lenses and poorly aimed blown kisses. Rejuvenate earth’s storage facility with today's Groupon: for $25, you get core lawn aeration from Greenside Lawncare in St. Charles (a $50 value).

Greenside's lawncare professionals prune and nurture lackluster yards back into lush landscapes of verdant, springy grass. Core lawn aeration helps build thicker, healthier turf that can fend for itself against weeds, diseases, bugs, and ornery lawn gnomes. Aeration helps break up headlocked lawns held fast by soil compaction and thatch layers by creating holes in the soil for oxygen and water to trickle through. The treatment encourages deeper root growth and better water retention, which makes for lower sprinkler bills and extra ammunition to spray at the neighborhood watch. Post-aeration, lawns are covered with the detritus of a successful extraction session, leaving coils of soil that are easily mowed over or broken up. Although recently aerated lawns may look rough and in poor condition, if aerated during active grass growth (late spring or fall), they quickly recover, yielding a plush outdoor carpet for Lilliputian blockbuster-movie premieres.

Each of Greenside’s lawn specialists boasts a solid foundation in sod cosseting, from knowing the intricacies of microbes and pH range to properly nurturing soil and dispensing reasonable weekly allowances.
