This is a simple task in land in good tilth. The holes need only be large and deep enough to hold the roots without undue cramping. Herein is again manifested the wisdom of thoroughly preparing the land; for, in well-prepared land, the hole is really as large as the vineyard. Even in the condition of poor tilth, deep holes are often a menace to the life of the plant, especially if drainage is not provided, for the deep hole becomes a tub into which water pours and stands to soak the roots of dying vines. An extra spurt in digging holes cannot take the place of perfect fitting of the land.

There is nothing to commend the practice of digging holes in a leisure time that all may be ready when the time to plant arrives. The vines will strike root best in the freshly turned, moist soil of newly dug earth, which can be firmly set about the roots when the vine is planted. Neither is time saved in digging beforehand, for the sun-baked and rain-washed sides of holes long dug would surely have to be pared afresh. It is, however, quite worth while to throw the surface soil to one side and that lower to the other, that a spadeful of moist, virile, surface soil may be put next to the roots.

There are, no doubt, some soils in which the holes might be blasted out with dynamite, as, for instance, in a shallow soil with the hardpan near the surface and good subsoil beneath. It is very questionable, however, whether these defective soils should be used for commercial plantings as long as there still remain unplanted many acres in all grape regions of good deep land for the grape. To such as are attracted by "dynamite farming," minute descriptions of methods of use of dynamite and even demonstrations may be secured from manufacturers of the explosive.
