For 43 years, Blue Tree has designed and installed custom gardens across Southeastern Pennsylvania. Degreed designers, not just crews, plan every bed for the soil, light, and the way you live, then our own installers bring the plan to life. The result is a garden that looks intentional the day it goes in and only grows into itself from there.
A garden is the layer that makes a landscape feel finished: the planting plan, the seasonal color, and the structure that carries a yard through winter and back into spring. Blue Tree designs gardens as part of the whole property, not as a tray of plants dropped along the foundation. A degreed designer studies your soil, drainage, sun, and the way you actually use the yard, then draws a planting plan matched to Southeastern Pennsylvania's clay soils, humid summers, and cold winters. Blue Tree has planted gardens across Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties since 1983, pairing native and proven ornamental species so the garden fills in, holds its shape, and looks intentional in every season.

Southeastern Pennsylvania sits across USDA hardiness zones 6b and 7a, so plant selection has to account for cold winters and hot, humid summers in the same plan. The region's clay-heavy soils hold water and run acidic in places, which makes soil testing, amendment, and drainage part of the design rather than an afterthought. Deer pressure is real across much of Montgomery, Bucks, Chester, Delaware, Lehigh, Berks, and Philadelphia Counties, and microclimates shift from a north-facing slope to the heat reflected off a patio or pool. Blue Tree has planted in these conditions since 1983, choosing proven performers over trend plants and drawing on 43 years of installation data so the garden establishes, fills in, and holds up season after season.
LED Landscape Lighting. Extend the garden into the evening with uplighting on specimen trees, soft path lighting through the beds, and accent lighting on focal points. Explore landscape lighting.
Drip Irrigation. Automated, low-volume watering that takes the guesswork out of establishment and keeps new plantings healthy through their first summers. Explore drip irrigation.
Seasonal Mulching and Bed Care. Annual mulch to hold moisture and suppress weeds, plus ongoing bed maintenance handled by the same team through Premier Outdoor Services.
Most garden design and planting projects from Blue Tree run from about $5,000 for a focused bed refresh to $50,000 or more for a full-property planting plan with mature specimen trees, as of 2026. The number depends on bed size, plant species and maturity, soil and drainage work, and access. Every project starts with a free on-site consultation and an itemized proposal, so you see what each part of the plan costs before you commit.
Southeastern Pennsylvania sits in USDA hardiness zones 6b and 7a, so the strongest performers handle cold winters and hot, humid summers. Blue Tree leans on proven natives and adapted ornamentals: oakleaf hydrangea, itea, viburnum, switchgrass and other native grasses, coneflower, and deer-resistant choices like boxwood, Russian sage, and ornamental alliums where deer pressure is high. Your designer matches species to your exact light, soil, and moisture rather than a generic plant list.
Spring and fall are the two best windows in Southeastern Pennsylvania. Fall is often ideal because the soil is still warm, rainfall is steadier, and roots establish before winter without summer heat stress. Spring planting works well too, especially for perennials and annual color. Blue Tree installs through the full growing season and times each project to give the plants the best start, then provides a watering guide tuned to the season you plant in.
Yes. All plant material Blue Tree installs is backed by a one-year, one-time replacement warranty from the date of installation, provided the watering guide is followed. Garden success depends heavily on establishment care in the first season, so every project ships with a watering plan tailored to your plant material and site, and your designer stays available for care questions.
It depends on the design, and that is a choice you make with your designer. Blue Tree can plan a lower-maintenance garden built around shrubs, native grasses, and long-lived perennials, or a higher-touch garden with seasonal color and detailed beds. Either way, ongoing mulching, pruning, and bed care are available through Premier Outdoor Services, handled by the same team that designed and planted the garden.
