Three Decades of Landscapes Built to Last

DELIS Landscaping is a Pennington-based design-build studio serving Central New Jersey and Bucks County, Pennsylvania, and surrounding area. Founded in 2009 by Rich Green after twenty years in the field, we design, install, and maintain residential landscapes that hold up to time, weather, and the way people actually live outdoors.

How DELIS Started

Rich Green grew up around horticulture. He studied Landscape Architecture at Ohio State, then earned a Bachelor of Science in Ornamental Horticulture from Delaware Valley College in 1993. For the next sixteen years, he worked as a foreman and then Residential Landscape Production Manager — running crews, designing installations, and learning the hard lessons that come from being on a job every day instead of behind a desk.

By 2009, he'd seen enough of how the industry worked — and how it should work — to start his own. DELIS Landscaping opened that year with a simple idea: handle the whole project. Design through maintenance. One team, one warranty, one phone number. No subcontractor surprises, no design-in-isolation problems, no maintenance crew showing up to mow over an installation no one explained to them.

Seventeen years later, the company is still in Pennington, still owner-operated, and still doing it the same way.

The People Doing the Work

DELIS is a team of about fifteen — designers, foremen, hardscape installers, plant specialists, and maintenance crew. Most of them have been with the company for years. Installation crews focus on hardscape and planting; maintenance crews focus on ornamental care and lawn programs. The two specialties stay separate so each one stays sharp.

We invest in continuing education at Rutgers, attend regional trade workshops, and stay current on the materials, methods, and code requirements that change every season. The owner is on jobsites daily. The crew owns its work.

oUR APPROACH

Every property is different. The design that worked next door won't necessarily work on your land. We start every project by walking the site, listening to how you use the space, and understanding what's already working — before we propose changes.

We're not a national chain installing kits from a catalog. We design for what your soil, drainage, and microclimate actually require. We pick plants that survive a Pennington winter. We build hardscape that doesn't heave when the ground freezes.

And once the project is done, we're still around. Many of our design-build clients become long-term maintenance clients — some have been with us for over a decade.

Tell us about your project. We'll set up a free on-site consultation within a few business days.
