Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the rootstock.

How do you tell if a tree is grafted?

Look for an abrupt change in the circumference of the trunk or in the texture of the bark. The graft, or bud union, is a distinct scar on the citrus tree trunk where the bud from the scion was originally joined to the rootstock.
