and sprout long before they could be planted in spring. 

 Hence there would be loss. 



177. Burying hardwood cuttings bottom end upwards 

 from a few days to a few weeks in spring before setting in 

 the cutting bed takes advantage of heat in the upper 

 layers of soil. It is of particular advantage with cuttings 

 slow to take root ; for instance, certain varieties of grapes, 

 such as Norton and Delaware. Usually, for convenience 

 in handling, the cuttings are tied in bundles (Fig. 107) of

Shelves are used for such plants as cannas, dahlias, gladiolus, placed in 

 boxes. Potatoes and other roots are generally stored in piles or bins.

 posed to the sun and only two or three inches deep. 

 Often frames are used (Fig. 106). Sometimes cuttings 

 are so treated in fall and taken up for cellar storage when 

 the ground begins to freeze hard; sometimes they are 

 stored without this previous treatment, but buried in 

 spring for a few weeks before planting. Hardwood 

 cuttings grown out of doors do best when of medium 

 (six or eight inches) rather than extreme length because 

 they are warmer from the natural bottom heat. 



178. Semi-hardwood cuttings, those of nearly mature 

 but still green wood, are used to propagate many hard-
