56. CUTTINGS AND THEIR USE IN PROPAGATION. 



The more common forms of artificial reproduction are 

 by cuttings, grafting and budding. A cutting is a de- 

 tached portion of a plant inserted in soil (or in water) 

 for the purpose of producing a new plant. Cuttings may 

 be divided into three classes : 1. Hard-wood cuttings. 2. 

 Soft-wood cuttings (herbaceous). 3. Root-cuttings. 



1. Hard Wood Cuttings. A hard-wood cutting is a 

 cutting from the ripened wood of a deciduous plant of the 

 present or previous season's growth. The cultivated 

 plants most commonly propagated by the use of hard- 

 wood cuttings are grape, olive, fig, quince, currant and 

 gooseberry, and many ornamental shrubs, such as privet, 

 tamarisk, hydrangra, etc. 



2. Soft Wood Cuttings. This class of cuttings is ex-

 roses, carnations, geraniums, fuchsias, begonias, etc. Leaf 

 cuttings are often employed in multiplying begonias, cacti 

 and other plants having thick fleshy leaves containing a
