The grape is propagated easily from seeds, layers, cuttings of the new wood, and by grafting. It is only grown from seeds where attempts are made to develop new varieties by crossing or selection (110. Speedy Testing of the Crosses and Hybrids). The different modes of layering are outlined in sections (52. Summer Layering) and (53. Spring Layering) and growing by cuttings in sec-tion (60. Spring-planted Cuttings).
In growing vines from cuttings commercially, specially favorable soils are selected. As an instance, in Iowa they succeed best on the loess soils of the Missouri slope, as this soil is very fine in texture of its particles and favorable for drainage in wet periods and for the ascent of moisture from below in dry ones. In New York for the same reasons grape-vines are grown commercially on the finely comminuted and well-drained soils on the east shores of Lake Erie. While it is true that grapes can be grown from cuttings on almost any soil, it is yet true that only special soils and subsoils will develop strong one-year-old vines with long and strong roots.
