Testimonial

What High-End Estate

Homeowners Say

Ward and his team completed two complex projects for our Silicon Valley client at their Sunnyvale campus. One involved redesigning a large atrium’s hardscape, requiring careful weekend transport of heavy materials through a newly renovated cafeteria—executed flawlessly without disrupting operations. They also revamped the main entrance planters, replacing an unsatisfactory installation with a more elegant and formal design. Their work is always thoughtful, precise, and completed with minimal disruption. We trust Petrus Landscaping for all large-scale projects, knowing they deliver exceptional results every time.

Carmen Jiron

I have been working with Ward, Gabe and their team of gardeners at my clients estate for the past 5 years. I have found them to be reliable, professional, and extremely knowledgeable of landscapes. They certainly know their plants, and have been instrumental in bringing a fine level of detail to the estate I manage. Their team of gardeners are respectful, attentive, and go above and beyond to create the well manicured gardens that the estate requires.

Darryl H

Estate Manager, Los Altos

Petrus Landscaping transformed our steep hillside yard with beautiful features like a stone staircase, pond, tiered garden beds, and drought-tolerant planting with an automated drip system. The team was professional, thoughtful, and delivered results beyond what we imagined.
