What is bark grafting?

Bark grafting is a horticultural technique used to propagate plants by joining a scion (a young shoot or twig) onto the bark of a rootstock. This method is particularly effective for woody plants and is performed during the growing season when the bark is easily separated from the wood beneath. The cambium layers of both the scion and rootstock must be in contact for successful healing and growth. Bark grafting is commonly used to combine desirable traits from different plant varieties, such as disease resistance or fruit quality.
