Grafting Vegetables

Vegetable grafting is a centuries-old technique utilized in Asia to improve plant production, reduce disease susceptibility, and increase soil utilization. Vegetable grafting was introduced in the United States almost 20 years ago and growers are becoming more aware of its attributes and potential. At Washington State University, we began vegetable grafting in 2009 with three crops: tomato, eggplant and watermelon.
