DEVELOPING SAFE CULTURAL PRACTICES FOR WATER SPINACH (IPOMOEA AQUATICA) IN THE STATE OF GEORGIA, USA

Water spinach (Ipomoea aquatica) is a tropical plant often grown and consumed in its native regions as a leafy green vegetable. In the U.S., it is classified as a noxious weed by the USDA due to its potential invasiveness in certain temperate regions. Georgia, USA has recently permitted imports and sales of water spinach into the state while cultivation is under consideration. The objective of this study was to develop safe cultural practices to provide for future Georgia growers due to a lack of current accessible growing information. An evaluation of nutrient requirements, planting and harvest periods, and fertilizer regimes was studied. Studies revealed that a 0.50 strength Hoagland’s solution should be considered as a baseline fertility program in a hydroponic setting while high tunnel studies determined planting in May is an ideal time to plant water spinach outdoors to maximize yield.
