Therefore, it must be protected from direct sun- light and dry air until it is well established; and if it has many leaves, some of them should be removed, or at least cut in two, in order to reduce the evaporating surface. The soil should be uniformly moist. The pictures show the depth to which the cuttings are planted. For most plants, the proper age or maturity of wood for the making of cuttings may be determined by giving the twig a quick bend:
