top one. This is the best method for general purposes. 

 Cuttings may also be taken below the joints when the 

 shoots are half mature. The cuttings require mild bot- 

 tom heat. For greenhouse ornament in fall and winter, 

 excellent specimens may be secured from cuttings made 

 in summer from such stock plants.
