with buds at their joints, as seen on their aerial canes 

 and branches ; but the roots of these plants produce ad- 

 Tentitious buds from any and all parts of their surface 

 alike, consequently in dividing them for making cuttings, 

 we pay no attention to any surface indications of roots or 

 buds. But in employing the true subterranean branches 

 for cuttings, we divide them on the internode, preserving 

 one, two or more joints with their dormant buds on each 

 cutting. If one of these buds pushes and forms a sprout, 

 it is sufficient, but sometimes all will grow, producing a 

 greater number of plants, but less vigorous ones. 



The after-treatment of cuttings made of subterranean 

 branches should be very much the same as that given to

root-cuttings, although it will usually require less time 

 for developing the dormant buds at their joints than to 

 produce adventitious buds on true roots. In making 

 such cuttings, the ordinary pruning shears (figure 69) 

 may be employed, instead of a knife, for a very smooth 

 surface to the severed parts is not so necessary as in mak- 

 ing cuttings of the twigs and young shoots of ligneous 

 and herbaceous plants. 



To avoid repetition, I will say here that wherever in 

 the following pages root-cuttings are mentioned as a mode 

 of propagation, it will be understood that they are to be 

 made and preserved as desciibed in this chapter. Any 

 variation in treatment which may be required will be 

 noted as it may occur.
