PROPAGATION 41 



gating 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 propa- 

 gated 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. 



There are several ways of making single-eye cuttings. The 

 most common form of the cutting is the single bud with an inch 

 of wood above and below, the ends being cut with a slant. 

 Some modify this form by cutting away the wood on the side 

 opposite the bud, exposing the pith the whole length of the 

 cutting. In another form, a square cut is made directly under 

 the bud, leaving an inch and a half of wood above. Or this last 

 form is modified by making a long sloping cut from the bud to 

 the upper end, thereby exposing the maximum amount of 

 cambium. Advantages are claimed for each form, but these are 

 mostly imaginary, and the cutting may be made to suit the 

 fancy of the propagator if a few essentials are observed. 



Single-eye cuttings are made in the fall and are stored in sand 

 until late winter, about February in New York. At this time 

 the cuttings are planted horizontally an inch deep in a sand 

 propagating bench in a cool greenhouse. If the cuttings are 

 not well calloused, they remain one or two weeks in a tempera- 

 ture of 40 to 50 without bottom heat, but well-made cuttings 

 are calloused and ready to strike root so that brisk bottom 

 heat can be applied at once. After six weeks or two months, 

 the young plants are ready to pot off or to transplant in a cold- 

 frame or cool greenhouse. If but a few plants are to be grown, 

 they may be started in two- or three-inch pots, shifting into
