Gis forGraft
Grafting is a process of making a piece of a plant grow by attaching it to another plant. This process is often used to attach a tree that is a good bearer of fruit to another that has strong roots, combining the best qualities of two plants. It can also be used to have different but related kinds of fruit growing on the same tree.
The graft in the picture has been made by cutting a slit into the stem of the host tree and putting a stem from another tree into the slit.
