Horticulture

Horticulture is often defined as the art and science of growing plants – flowers, fruits, vegetables, trees and more! Research shows an intimate connection between people and plants – fresh fruits and vegetables feed and nourish our bodies, trees shade and cool the places we live, flowers brighten our landscapes, and as research shows, our spirits too.
There is another side to horticulture as well. Invasive pests destroy our natural resources at a large financial and environmental cost. Additionally, the misuse and misunderstanding of pesticides causes pollution and health risks. Division of Extension programs aid in finding the appropriate, most cost effective and environmentally sound solutions that are best for you.
As the demand for horticultural products increase, Division of Extension programs aid in finding the appropriate, most cost effective and environmentally sound solutions that are best for the individual.
