Testimonials
Recognized for pioneering approach to landscape design that blends artistry, technology, and environmental consciousness.
Excellent services provided by Ward and his team! They are skilled in their craft and dedicated to providing immaculate service!
Amazing service, really enjoyed working with the Petrus team to help us set up and keep the landscape in our properties looking stunning!
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.
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.
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.
