- Experienced design teams with strong client follow-up

- 14-plus-year repeat client relationships

Guevara Landscaping LLC
Why it ranks sixth
Guevara's recent reviews are five-star and specifically call out punctuality and clear communication during landscape projects. The review count is small, so this is one to watch as more jobs come in.
Pros
- Professional, punctual crews
- Clear communication on-site
Watch out: One older complaint mentions unresponsiveness on a scheduled snow removal day, though recent reviews don't repeat that issue.
Services: landscape design installation, lawn care maintenance, snow removal
Oliver Nurseries
Why it ranks seventh
Oliver Nurseries in Fairfield draws steady praise for rare, healthy plants, on-site design consultation, and immaculate display grounds. Recent four- and five-star reviews suggest the customer experience has improved compared with older feedback.
Pros
- Rare and specimen plant inventory
- On-site design consultation for yard redesigns
- Knowledgeable plant staff when engaged directly

Red Carpet Landscaping
Why it ranks eighth
Both reviews on file for Red Carpet describe genuine transformations, including a front yard that now stands out on the street. It's a small sample, but both reviewers recommend the company without reservation.
Pros
- Landscape design work described as transformative
- Professional installation execution
Watch out: Only two reviews are on record so far, which limits how much weight the rating can carry.
Services: eco friendly organic, lawn care maintenance, landscape design installation
McLaughlin and Sons Landscapes
Why it ranks ninth
McLaughlin and Sons operates under Licensed Landscape Architect #CT-1299 with more than 20 years in business, and its two reviews describe solving specific problems, restoring privacy after tree loss and transforming an overgrown yard, on time and on budget.
Pros
- Licensed Landscape Architect credential (#CT-1299)
- 20-plus years of operating history
Watch out: Only two reviews are on file, so the track record here is thin so far.

Retana Landscaping LLC
Why it ranks tenth
Retana is listed as a landscape design and installation specialist in Connecticut, but there aren't yet enough reviews to say how the work holds up in practice. Worth a direct conversation before committing to a larger project.
Pros
- Listed specifically as a landscape design and installation business
- No negative reviews on record
- Profile details are filled in for direct contact
Watch out: No reviews yet, so there isn't a customer track record to evaluate.

American Landscape
Why it ranks #11
American Landscape appears in Connecticut's landscape design and installation category, though its profile is sparse and there's no review history yet to draw on. It may be worth a direct call to check current availability and portfolio.
Pros
- Listed as a landscape design and installation provider in Connecticut
- No negative reviews recorded
Watch out: The listing is largely unverified with no reviews yet, so there's little independent evidence of service quality.
