Landscape Design & Installation in New Castle County, DE
Union Park Landscaping designs and installs custom landscapes for homes across Wilmington and New Castle County — garden beds, foundation plantings, trees, shrubs, and perennials chosen specifically for Delaware's climate and soil. Every design starts with how you actually use your yard, and every plant is installed with proper soil prep so it thrives instead of just surviving.
Whether you want a full front-yard makeover, a low-maintenance foundation planting, or a backyard that finally feels finished, we handle design and installation with one local crew — no subcontractors, no handoffs.
A new landscape design makes sense when…
- Your foundation plantings are overgrown, woody, or hiding your windows
- Beds look patchy no matter how much mulch you add
- You've bought plants that keep dying in the same spots
- You're preparing to sell and want serious curb appeal
- Your new-construction yard is a blank slate of builder-grade grass
How we work
- Walk & listen. We walk your property with you, talk about how you use the space, what you like, what you hate, and your maintenance tolerance.
- Design & quote. You get a planting plan and a clear written estimate — plant list, quantities, and pricing with no vague allowances.
- Install & guarantee. Our crew preps soil properly, plants correctly (depth, spacing, root flare), mulches, and walks the finished work with you.
Built for Delaware conditions
Delaware sits in USDA hardiness zone 7a–7b with heavy clay soil in much of New Castle County. We design around that reality — amending clay beds, choosing plants like inkberry holly, itea, oakleaf hydrangea, coneflower, and switchgrass that handle our humid summers, and placing deer-resistant species in neighborhoods near woods like Hockessin and Greenville.
What it costs
Most planting projects in New Castle County run $1,500–$8,000 depending on size and plant maturity; full front-yard redesigns with larger trees typically run more. Estimates are free and itemized.
Landscape Design questions, answered
How much does landscape design cost in Delaware?
At Union Park Landscaping, design consultation is built into the project — you don't pay a separate design fee for typical residential work. Most complete bed redesigns with plants and mulch fall between $1,500 and $8,000 in New Castle County.
What plants grow best in New Castle County?
New Castle County is USDA zone 7a–7b. Reliable performers include inkberry holly, oakleaf hydrangea, itea, viburnum, coneflower, black-eyed Susan, switchgrass, and serviceberry. We favor natives and deer-resistant varieties where deer pressure is high.
When is the best time to plant in Delaware?
Spring (March–May) and fall (September–November) are ideal — plants establish roots before summer heat or winter cold. We install through the whole growing season with proper watering plans.

Yes. We plant correctly and stand behind our work with a satisfaction guarantee. We'll also leave you simple watering instructions — the #1 factor in first-year plant survival.
