Abstract
The wedge grafting technique is described in detail for students, nursery growers and technologists. Formerly considered as very difficult to accomplish and with poor results, this technique is now yielding very high graft success beyond 95% in rambutans, lychees, longans and other fruit trees in Costa Rica, and 100% in mangosteens by beginners such as the students at EARTH University in Costa Rica. This technique, which has been pioneered in the Philippines, has become a major boost for the rise of rambutan production and exports in Central America, and is on its way for applications in lychees, longans, avocados, mangos, mangosteens and others. It is now used in Honduras, Guatemala, Costa Rica and Brazil for these crops.
