Unkempt lawns, like heads shampooed with Mountain Dew, are plagued with stunted growth, premature bald spots, and a neon-yellow tinge. Feed lawns to help them flourish with today's Groupon: for $42, you get 6,000 square feet of lawn aeration from Kapp's Lawn Specialists (an $84 value).

Family-run for more than 40 years, Kapp's Lawn Specialists nurtures dusty yards into evergreen pastures. A professionally trained and certified botanical buff punctures healthful holes in up to 6,000 square feet of grass lawns or dirt plots in preparation for seeding. Core aerators pull plugs of compacted topsoil from the earth's crust, creating channels for water and nutrients to trickle into grass root systems. Newly turned soil boosts blade growth, thickens the rug's verdant pile, and increases drought resistance. Clients should reveal any subterranean sprinkler systems and invisible dog fences to the technicians, but lawn owners are not required to be home during the procedure, unless their lawns happen to be locked in garages. Tender yards that have been sodded within the last six months are ineligible for aeration.
