In making the cuttings, a slanting cut is made close below the lowest bud, while about an inch of wood is left above the upper bud. When possible, a heel of old wood is left at the lower end; or, still better, a whorl of buds, as roots usually start from each bud. The finished cuttings are tied in bundles, all butts one way, and are then ready to be heeled-in. This is done by burying in trenches, butts up, and covering with a few inches of soil. It is important to invert the cuttings in trenching, since otherwise the tops often start to grow before the butts are properly calloused, and it is very essential that the tops remain dormant until roots appear to support the new growth. _Planting the cuttings._ Cuttings are planted in the nursery in rows wide enough apart for cultivation and two or three inches apart in the row. Trenches are made with a plow; perpendicular if the cuttings are shorter, and a little slanting if longer than six inches. The cuttings are set at a depth which permits the upper buds to project above the ground, as shown in Fig. 6. When the cuttings in a row are placed, two inches of soil are put in and pressed firmly about the base of the cuttings. Then the trench is evenly filled with earth and the cultivator follows. Doing duty by the young plants consists in cultivating often during the summer to keep the soil moist and mellow. [Illustration: FIG. 6. Planting cuttings.] The cuttings are planted as soon as the ground is warm and dry enough to work. To delay planting too long invites injury from drought, which almost annually parches the land in eastern America. Irrigation gives more leeway to planting time in the West. When warm sunny weather, accompanied by an occasional shower, predominates, the cuttings start growth almost at once, as shown in Fig. 7, and by fall, all things being propitious, make a growth from four to six feet. With the cuttings three inches and the rows three feet apart, 58,080 vines may be grown to the acre. [Illustration: FIG. 7. A cutting beginning growth.] _Single-eye cuttings._ New and rare varieties are propagated from single-eye cuttings, thereby doubling the number of plants from the propagating wood. This method gives an opportunity, also, to start the work of propagating early in the season, since single-eye cuttings are nearly always rooted by artificial heat. But the greatest value of the method is that some varieties which cannot be propagated in any other way readily grow under artificial heat from single-eyes. Well-grown vines so propagated are as good as those grown by any other method, but the great disadvantage is that unless much care and skill are used, vines from these cuttings are poor and quite worthless. It is also a more expensive method than growing from long cuttings out of doors.
