Many lilies can be multiplied by removing scales from the mature bulb. Dust the scale with a fungicide and place, base end down, in a moist growing medium in a warm, protected area. Bulblets will form at the base of the scale. 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.
