Yuccas are in no sense difficult subjects, provided they 
are planted in rich light soil. Where such a description 
will not apply to the natural garden soil, a pit must be dug and filled up 
with suitable material, in which the Yucca, if a hardy species, may be 
planted. If a greenhouse species, it should be planted in a tub, which 
can be turned outside in summer and sunk in the ground. Yuccas require 
a considerable space to show them off properly. They look well at the 
far end of a lawn, or in a shrubbery border with a sunny position. They 
are propagated by means of suckers that sometimes shoot up from the 
roots, and these require merely separating after they have thrown out 
independent fibrous roots, and planting outside. Where these do not 
appear, cuttings may be made of the side shoots, and these, inserted in 
sandy soil, in gentle heat, will soon root. In some eases the stemless 
species may be divided without seriously marring the’ effectiveness of 
the tuft. |
