In everycase when tops are finally cut off, the stubs are cut oftsmoothly, ch^se to the buds, to favor healing withoutscars. Staking the young trees is necessary, because theunions are at first weak. 271. Grape grafting is usually a necessity only (T) forworking t)ver undesirable varieties or seedlings to desiredkinds and (2) for growing European varieties in regionswhere the phylloxera (280) exists. The former, scarcelya nursery practice, is made by cleft grafts below the soilsurface, without tying or waxing, but with earth mounded 212 PLANT rkOPAGATION over the union and up to the upper bud. The latter isdone in a variety of ways (Fig. 175). The reason fordoing it is that American stocks, the ones always used,are less susceptible to phylloxera injury than areEuropean varieties.
