Unlike swimming holes or children riding NASA's merry-go-centrifuge, grass always looks more attractive when green. Maintain a fresh shade with today's Groupon: for $28, you get one organic-fertilizer application from Greener Grass, serving Calgary and Airdrie (a $57 value).

Greener Grass nurtures weary lawns back to lushness with three fertilizing and weed-control programs, including an organic regimen for environmentally minded sod owners. Enhance up to 3,000 square feet of lawn with an application of organic fertilizer, packed with soil-building iron to thicken grass and bolster earthworm endurance in subterranean jousting tournaments. A lush, green lawn usually sprouts after four fertilizer applications, but the first treatment sets yards on the path to vibrancy and spares them the embarrassment of covering up bald spots with picnic blankets. Knowledgeable lawn wranglers are on-hand to answer questions about watering and mowing and to distribute lawn-care tips, ensuring grass lives up to its verdant potential.
