and eiuiiui by making as many divisions as tliere are buds, 

 or rather separate crowns, as shown in Fig. 32. 



Some of tlie scaly-bulbed lilies can also be divided and 

 yet remain strong for flowering if 

 separated in sections as indicated 

 by the bulb, as shown in Fig. 33. 



As to the time most favorable for 

 division, at the North the spring is 

 the best period for separating hardy 

 perennials, as it is the period of 

 starting growth. But in mild 

 climates the work is usually done 

 in winter or very early spring. 



But we have many kinds of 

 bulbous or tuberous plants that 

 make all their growth early in spring ®'°'^' 

 and rest in summer, such as the narcissus, hyacinth, tulip, 

 dicentra, and perennial poppy. In such cases the division 

 follows the ripening of the foliage. 



With tubers and rootstalks, such as the dahlia and 

 canna, the season for division is in the dormant period in 

 autumn, or prior to time of planting in the spring.
