Letter VII. Propagation by Leaves. 



This is a mode of propagation which has become quite as 

 common, and fidly as successful, as propagation by cuttings; 

 and, indeed, I consider it the easiest and most successful mode 

 of increasing such exotics as gesneras, gloxinias, Hoya car 

 nosa, &c. &c. 



The state most favorable for rooting leaves, is when they 

 have completed about three parts of their growth. Let the 

 leaves of the desired kinds be taken off close to the stem, and 

 inserted into pots, such as were recommended for cuttings, pre- 

 pared in the same manner. The whole of the leaf-stalk and 

 about half an inch of the leaf should be covered, and laid in 

 a slanting direction, when they should have a sprinkling of 

 water, the bell-glassns put on, and removed to the propagatmg- 

 house, or a previously prepared hot-bed, where, if kept uni- 

 formly moist, warm, and the bell-glasses regularly wiped inside 

 every morning, they will soon strike root ; but care must be 

 taken to shade them in bright sun-shine, in order to prevent 

 excessive perspiration until they emit roots ; after which they 

 may be fully exposed to the light. Should any happen to 

 damp off, let them be immediately removed, otherwise, they 

 might endanger the whole. As soon as the leaves begin to push 

 young shoots, the glasses may be taken off and the pots re- 

 moved to a dry shed, there to remain for a ^e\v days previous 

 to their being potted off.
