Horticultural scientists are responsible for product development within the horticulture industry. This involves conducting research to develop new and improved plant varieties, as well as developing new methods of cultivation. In addition, horticultural scientists work to improve the quality of existing plant products and to find ways to increase yields. Horticultural science is a highly interdisciplinary field, and scientists often collaborate with other professionals, such as engineers and marketing specialists, to bring new products to market. The work of horticultural scientists has a direct impact on the quality of the food we eat and the health of our environment.
