A Detailed Guide to the Top-Grafting and Cultivar-Change Technique for Pear Trees: Methods and Key Points

Pear trees are extremely widely distributed in China and come in a great many cultivars. When planting pear trees, many people are not sure which cultivar they have, and only discover once the trees bear fruit that the cultivar is a poor one. Replanting at that point costs both time and effort, so the top-grafting and cultivar-change technique emerged to solve this problem. This so-called top-grafting and cultivar change uses the existing framework of the pear tree, combining long and short scions, to change the cultivar in a single operation, so that even low-yielding trees can achieve high yields. So how is it done? Let's take a look together.
