 overcrowded, that the vines are not wrapped 

 around each other, and then cut off a part of the 

 tap-root. This root should be cut off about twenty

 screen is desired. The growth, however, is slow, 

 which is true of all perennials, and some quick- 

 growing annual should be planted with it for im- 

 mediate effect. 



Zinnia 



Given a strong rich soil to begin with, no more 

 attention need be paid the zinnia and it will 

 flourish on poor soil. 



The zinnia is particularly adapted for outdoor 

 growth. It is not delicate enough to be attractive 

 for use as a house plant or for cutting purposes.
