METHODS OF PLANT PROPAGATION 15 



leaved begonias, are easily propagated by means of leal 

 cuttings. The method is simplicity itself. A fully-grown 

 leaf is removed from the plant, laid upon moist sand in a 

 warm frame, the principal ribs pierced by fine pegs, and 

 held thereby in contact with the soil. Roots will form at 

 each of the points of contact, and a corresponding number 

 of new plants thus produced. Gloxinia leaves may be 

 treated in the same way, or the stalk, end may be thrust 

 into the soil, after the manner of a stem cutting. 



Other plants, again, may be multiplied by root cuttings. 

 The roots are simply cut into lengths of one or two inches 

 and planted. Horse radish is perhaps the commonest 

 example of plants multiplied in this way. 



Tubers, again, which contain more than one eye or 

 shoot, may be divided into as many portions as there are 

 eyes. This applies to the potato and dahlia among other 

 plants.
