Marshall Gardens - Sag Harbor's Best Landscaping

We tackle drainage issues head-on with professional earthmoving and regrading services. By carefully reshaping the land's contours and installing proper drainage systems, we redirect excess water away from your home's foundation and low-lying areas. This foundational work is often paired with strategic landscaping, like building retaining walls or installing permeable hardscapes, to create a dry, stable, and usable yard that lasts.

Dying plants in Sag Harbor are often due to soil conditions, pests, disease, or improper planting. Our certified arborists and horticulturists provide comprehensive tree and shrub care, including disease and insect management. We diagnose the specific issue, whether it's salt spray damage, fungal infection, or borers, and apply targeted treatments. We can also perform careful transplanting or removal and replant with species better suited to our local environment.

Absolutely. Our landscape design process is built on solving problems before they occur. We create master plans that incorporate smart irrigation design, proper grading for drainage, and the selection of native and salt-tolerant plants that naturally resist local pests and diseases. By integrating construction elements like retaining walls and raised beds, we build in resilience, ensuring your new landscape is beautiful, functional, and low-maintenance for years to come.
