CUTTINGS. 



Root Cuttings. — Many plants are propagated by root cuttings. A 

 root is cut into pieces three or four inches long, and these are then 

 placed in sliallow trenches, like seed in a nursery row. Each piece 

 of root Avill form a plant (Fig. H).

Stem Cutting. — A great many of our plants are readily propagated 

 by stem cuttings. This is one of the easiest and quickest ways of 

 propagating plants. Several methods of making stem cuttings are in 

 vogue. The simple cutting (Fig. 12) is the one most commonly prac- 

 ticed. It consists of a straight piece of branch having several buds. 

 A bud should be near tlie lower end. These are generally made in the 

 fall of half-ripened or well-ripened wood. They should be tied in 

 bundles of about fifty cuttings and placed in sawdust or sand in some 

 cool place, preferably a cellar.

A heel cutfing is like a simple cutting with a small portion of the 

 parent branch attached, which forms the '^^heel." Fig. 13a shows a 

 heel cutting of a grape. This cutting is more apt to form roots than 

 the simple cutting.
