Planting Services Guidance from Gary Duff Designs
Plantings are the part of a landscape that changes every year, which makes the initial selection matter more than most people expect. Here's what comes up first.
-
Plant selection starts with the conditions on your specific site, including sun exposure, soil composition, drainage, wind, and deer pressure. Gary Duff Designs then works backward from your home's architecture and the scale of the beds so the planting reads as intentional rather than assembled from whatever the nursery had available. Mature size drives most of the decisions, since a shrub that fits beautifully at installation can crowd a walkway or block a window within five years. The result is a landscape that holds its structure as it fills in instead of needing correction.
-
Maintenance level is a design choice, and Gary Duff Designs plans for whichever end of that range you want. Lower-maintenance plans lean on hardy shrubs, established perennials, and simpler bed shapes that hold their form without constant shaping or replanting. Higher-maintenance designs deliver more seasonal color and variety but ask for real attention through the year. Telling us your preference at the consultation produces a very different plan than discovering it after installation.
-
Native and adaptive species form the backbone of most Gary Duff Designs planting plans. Plants suited to Long Island's coastal conditions establish faster, need less irrigation once rooted, and support pollinators and local wildlife. Adaptive non-native material still has a place where a specific form, color, or screening height is called for, so the plans blend both rather than treating native as an absolute rule. Long-term landscape health comes from matching plant to site, which is what sustainable design means in practice.
-
Renovating established beds is regular work for Gary Duff Designs, and it rarely requires starting over. Mature specimens worth keeping get evaluated first, then the plan reworks structure, layering, and bed lines around them to bring the whole composition back into balance. Overgrown foundation plantings, thinning beds, and gardens that have outgrown their original design are the most common reasons homeowners call. Pairing a planting refresh with patio or walkway updates often transforms a property without full replacement.
-
Planting costs are driven by specimen size, quantity, and how much bed preparation the existing soil requires. Mature trees and large specimens carry substantially more cost than younger material that fills in over several seasons, which is a real tradeoff between immediate impact and budget. Soil amendment, irrigation, and edging all factor into the number as well. Gary Duff Designs takes on select projects starting at $10K and outlines clear options during your consultation.
