What We Do

The Delaware Center for Horticulture inspires individuals and communities through the power of plants. Since 1977, we have cultivated a greener community by creating and maintaining the first Urban Farm in the city of Wilmington, beautifying public landscapes, planting and advising on the placement of urban trees, mobilizing volunteers, and hosting community events and educational programs, including our Branches to Chances® Return to Work program and our Neighborhood Tree Steward Program. Because much of our work occurs in low income neighborhoods with higher rates of disease, environmental contamination, and poor access to healthy foods, our educational efforts also emphasize the personal health and sustainability benefits of gardening.

DCH is the only nonprofit membership organization in Delaware that mobilizes and inspires community greening statewide in urban and suburban environments. By inspiring an appreciation for improving our environment through horticulture, education, and conservation, we have become a leader in improving and beautifying communities by harnessing the power of our members, volunteers, and staff to go out and make a difference.

Our members come from Delaware and the surrounding region and bring with them a passion for plants only matched by that of our staff members.

With more than 600 active and dedicated volunteers annually, we have a tremendous amount of community support, which allows us to accomplish the impossible.

Why It Matters

The work of DCH strengthens the social fabric and builds more livable towns and cities by enhancing the environmental, economic, and aesthetic qualities of our cities and state. Working together, we create neighborhoods that are healthier, more attractive, and more ecologically sustainable. Simply put, DCH is about people and plants.
