PROPAGATING BY CUTTINGS

Subsequent Treatment. Buds may start from the cions. 

 Rub them off so that cions serve only as carriers. If some of 

 the cions fail, replace them the following spring. The cions 

 will gradually increase in diameter until they have closed the 

 spaces between them. 



Modifications of tine 

 Operation, Some growers 

 merely loosen the bark of 

 the stock and slip the cions 

 under it, fastening them in 

 place. This is more diffi- 

 cult to do than to remove 

 a section of bark entirely 

 and gives no better results. 



6. Propagating by Cut- 

 tings. The grape, goose- 

 berry, currant, and blue- 

 berry may be propagated 

 from cuttings. Take 8- to 

 10-inch hardwood cuttings 

 of the grape, gooseberry, 

 and currant in the fall, from 

 vigorous mature wood of 

 the current season^s growi:h 

 (Fig. 153). These cuttings 

 may either be set in the 

 nursery row, covered with 

 a mulch to prevent freezing 

 and thawing, or placed in 



bundles and buried in sandy knolls with the bottom end up. 

 The butts of the cuttings receive the heat from the late fall 

 and early spring sun, which induces the formation of a callus 

 or coating of tissue over them. The cuttings may also be 

 stored in sand in a cool cellar and kept just moist enough 

 to prevent drying out. Cuttings also may be made in early
