Lawn-care services: how they stack up.

Promos from national lawn-care services are full of enticing promises. "A Beautiful Lawn can be yours!" says Scotts. "Providing curb appeal for 40 years," states Lawn Doctor. "Our Grass Is Greener," assures TruGreen. The message seems to be getting out: Americans anted up more than $44 billion in 2006 on professional lawn and landscape service. But was it money well spent, especially when you could do the work yourself and save hundreds of dollars?

To help answer that question, we enlisted three staffers in the New York metropolitan area to go through the consultation process with four of the largest national residential companies: Lawn Doctor, Scotts, TruGreen, and NaturaLawn, which is known for "green" lawn care. We then asked two turf experts, Keith Karnok from the Department of Crop and Soil Sciences at the University of Georgia and Martin Petrovic from the Department of Horticulture at Cornell University, to review the lawn service's analysis and proposed treatment.

Of course, your experience might vary since these are nationwide operations with hundreds of independent branches. Because of that, we didn't complete the lawn-care treatment and measure actual results.

Here's what we learned:

Services were similar. Despite claims about "tailored" and "specialized" programs, we found that the prescriptions were surprisingly alike. That's because most major lawn services use widely accepted lawn-care practices designed to cure a wide range of problems. "It's a cost-competitive, high-volume business," Petrovic explains.

As a result, you should have realistic expectations. "It's a long shot to think that a little bit of fertilizer is going to transform your lawn," Karnok says.

Technician competence varied. The companies described an intensive training process that combines classroom education with field training. But standards can be hard to enforce with franchises. So ask if the technician is from a franchise or company-owned branch. Ultimately, the quality and specifics of any lawn service depend on the individuals who make the analysis and apply the treatments.
