Lawns, like bananas, will wither, darken, and be blended into a smoothie if not maintained properly. Foster your yard's sense of self-worth with today's Groupon: for $49, you get a one-time fertilizer and limestone application for a lawn up to 4,000 square feet from Nutri-Lawn (a $120 value) plus $30 toward future lawn or tree-care programs. Nutri-Lawn serves King and Snohomish counties, from North Marysville to South Maple Valley.

Nutri-Lawn resuscitates withered greens with reliable, competent service that earned it top lawn-care-provider accolades from Puget Sound's Consumer's Checkbook magazine in 2009. Its greensward gurus spread an organic-based fertilizer that releases micronutrients into soil, helping lawns recover from drought or from messy breakups with golf courses. Then an application of Verde-Cal lime neutralizes soil pH, releasing nutrients that foster healthier grass growth. Both substances are safe to use around humans, pets, and chemically sensitive robot butlers. Additionally, Groupon holders can join one of Nutri-Lawn's lawn- or tree-care programs, receiving a $30 discount to cosset their courtyards with eight seasonally timed applications of fertilizer, pesticides, and other treatments.
