Layering

Layering is another vegetative method of propagation. This technique is successful because a majority of plants can be induced to produce roots on their stems. Such roots are called adventitious roots, and many plants do this naturally. Blackberry canes and forsythia branches may hang down so that their tips come in contact with the. ground and take root there. Success can be best ensured by placing a stone on the portion of the stem that is in contact with the ground, thereby preventing the tips from swinging back and forth with the wind. Several types of layering are represented in figure 37-2.
