A springy lawn has the power to launch obnoxious garden-party guests farther than the traditional method of shooting them out of a T-shirt cannon. Free your yard from unwanted visitors with today's Groupon: for $45, you get an Ecolawn full-lawn-fertilization treatment from R-green Organic Turf Fertilization Systems (a $90 value).

A 100% organic lawncare provider serving Lehigh Valley, R-green will restore a lawn's lustrous volume and vibrant green hues without relying on environmentally damaging products. With the Ecolawn treatment, four annual visits provide child- and pet-friendly maintenance with fewer applications than those of traditional fertilization methods.

This Groupon covers the first visit, which is composed of three services: organic fertilization with crabgrass pre-emergent and weed control, natural-surface insect prevention, and natural-disease prevention to keep weeds from clogging up the arteries of your driveway’s shrubbery. A proprietary compound utilizes chemicals that can be naturally broken down by microorganisms to use as food for growth at micro dinner parties. A generous 5% donation of all proceeds goes to the Chesapeake Bay Foundation, capping this guiltless greening of Mother Nature's carpets.
