LEAF CUTTINGS. There are yet two more sorts of cuttings 

 leaf cuttings and root cuttings. Leaf cuttings are rarely made in the 

 garden, but perhaps a friend has given the reader a slip of a Rex Be- 

 gonia. Remember to remove all but one leaf and oftentimes that 

 leaf needs shortening. The leaves removed can be cut up in small 

 pieces so that each piece has a portion of the heavy midrib at the 

 base. When inserted in sand several inches deep in a warm green- 

 house, the base will root and a young plant starts. 



ROOT CUTTINGS are interesting to make. Plants with rather 

 thick roots can usually be propagated by this method. A box will be 

 necessary for such propagation; it should be about three inches deep 

 and nearly filled with a light loam. The roots are cut into pieces an 

 inch and a half long, and are scattered over the surface of the soil 

 and covered about one-half inch deep with light soil. The box should 

 then be placed in shade, watered and covered with a paper. In a 

 short time shoots will start and the young plant can be transplanted 

 to another location. The following plants can be propagated by this 

 method: Polygonum, Euphorbia, Plumbago Larpentse, Saponaria, 

 Coronilla varia, Achillea, Japanese Anemone. 



There are a number of perennials propagated by this method 

 which succeed better when the roots are planted perpendicularly with 

 a little piece of the end protruding. They are usually fleshy rooted 

 sorts. Among the plants are: Italian Rorage (Anchusa), Plume 

 Poppy (Rocconia cordata), Dodecatheon, Stokes' Aster (Stokesia 

 cyanea), Ree Ralm (Monarda), perennial Phlox, Gaillardia, Gyp- 

 sophila, Helianthus rigidus, Thermopsis, Papaver, Statice, Rleeding 

 Heart, Peony. Lily of the Valley is increased by separating the 

 pips or individual crowns. Among the vegetables, Horseradish is so 

 propagated. Scotch and Moss Roses, Calycanthus, Lilacs and Rlack- 

 berries may all be propagated in this way. 



DIVISION OF PERENNIALS. Perhaps the commonest method of 

 propagation of perennials and the one which is easiest, is the division 

 of the clumps, the main crowns being cut into a number of pieces. 

 The plants should be divided very early in Spring before growth 

 starts, or late in the Fall. This is the most used method of propa- 

 gating Iris, Peonies and Phlox. German Iris should be so divided every 

 three, Phlox every four, and Peonies every six or seven years, while
