Never propagate green plants from pot roots. 



This is over-propagation. 



Use only strong, field-grown clumps for propa- 

 gation which have been grown from divided 

 roots for at least two generations, and which 

 have produced the finest blooms, true inform 

 and colour. 



I cannot too strongly urge, however, that by 

 whatever process propagation is carried out, the 

 matter of careful labelling is of the greatest 

 importance. When cutting up the tubers, a 

 wooden label with copper wire should have the 

 name clearly written upon it. The wire may be 

 pricked directly through the tuber itself without 

 any injury to it and securely fastened before lay- 

 ing it to one side. 



In rooting cuttings in sand, if many of one 

 variety are to be grown, a box for that variety 

 alone should be provided, and a large garden 

 label placed in it in a conspicuous position. If 

 only a few cuttings each of a number of varieties 

 are to be grown, set the cuttings into the sand 

 in rows, placing a pot label with the name of the 

 variety at the head of each row. 



When the plants are potted, force a stick 

 about eight inches long into each pot, and to it
