Tri-Hishtil brings together three pioneers in the agricultural industry from around the world to the Mountains of North Carolina to become a leader in plant grafting. Grafting is a very detailed procedure whereby a growth booster (the rootstock) is combined with a promise (the scion). The actual grafting of vegetables with soft tissue stems is an extremely sensitive process, but results in a strong plant with resistance against specific soil-borne diseases.
