In 1 to 4 years these bulblets will grow and be ready to flower. In separating the tubers, each must have a segment of the crown that contains at least one eye or bud. Rhizomes grow and develop buds along their length. The rhizomes can be dug and cut into sections that each contain at least one eye or bud. In grafting, the cambium layers of the two different segments are aligned and grow together.
Some plants graft naturally.
Ivy commonly grafts itself. Natural grafting occurs where two branches are in close contact over several years. Grafting allows gardeners to produce plants identical to a parent plant. It also allows growers to control size and shape of a tree or shrub. Apples are grafted onto root stock that regulates the ultimate size of the tree.
