A man's home is his castle, and his lawn is the lush carpet on which pages bring him sacrificial hoagies. Prune their regal entry with today's Groupon: to Lawn Co, serving the Granbury, Cleburne, Burleson, and Crowley areas. This Groupon is valid for residential lawns up to 5,000 square feet in area. Choose between the following options:

• For $20, you get a lawn aeration (a $40 value).
• For $30, you get a full lawn-fertilizing treatment and winter weed spray (up to a $70 value).

At Lawn Co, professional turf tamers Lloyd and Angie Pinkerton deploy friendly teams of lawn experts across local yards to maintain greens and beautify downtrodden tracts. During aeration, compact plugs punch holes into the earth to pave pathways for water and loosen soil, giving room for maturing roots to stretch out and mingle with eligible earthworms. Grass soon lays down new root systems, which can result in fuller, more robust growth. Alternately, a winter weed spray preempts nascent weeds and homeless Chia Pets from encroaching on verdant landscapes, and also scares off weeds that have already claimed squatter's rights. Malnourished lawns flourish under fertilization, which infuses immature tracts with such nutrients as phosphorus and nitrogen, helping them develop deeper voices and thicker, greener shag.
