Brazilian cherries need to girdle cherry trees: the method is to cut a circle along the base of branches with a double-edged girdling knife and tear off the cortex.

The technique of stripping bark at the base of a strong tree or long branch for more than 3 years is called girdling. The girdling around the physiological fruit-dropping period can promote the formation of flower buds on the upper branches of girdling parts. The skin of a cherry is not as easy to peel as an apple tree. When peeling, you can use a sharp knife to help peel, and you must not hurt the cambium. The cutting edge of ring cutting should be smooth, which is beneficial to wound healing. Circumcising cherry trees must be used with caution, because it will produce a physiological reaction of gum production.
