The following kinds of herbaceous-grafting are in use in France and 

 Belgium : 



Grafting on fleshy roots, as in the dahlia and peony, may be per- 

 formed either with a growing shoot (fig. 216), or with a dormant eye, 



as in fig. 217. The 

 former mode requires 

 no explanation ; by the 

 latter, on the neck of a 

 barren tubercle a small 

 hole is made, in which 

 the bud is inserted, 

 but in such a manner 

 that its base shall be 

 perfectly on a level with 

 the surface of the tu- 

 bercle, and the edges Peg-grafting the

ing-wax. The tubercle 



is then planted in a pot, care being 

 taken not to cover the bud, and the 

 pot is plunged in heat under glass. 

 When the plant has taken, it may, if 

 hardy, be turned out into the open 

 border. This mode of grafting, ap- 

 plied to Dahlia imperialis, dwarfs the rampant habit of that plant and 

 causes it to flower more freely. 



Herbaceous wedge-grafting (fig. 218) is effected by paring the scion 

 into a wedge shape, and inserting it into a corresponding slip in the 

 stock. It succeeds well both with trees and herbaceous plants, more 

 especially when the plants are in pots so that they may be plunged in 

 heat and covered with a bell-glass. 



Herbaceous-grafting for shoots with Opposite Leaves (fig. 219). In 

 the middle of the shoots, between two opposite eyes, an angular and 

 longitudinal incision is made, 

 and a small portion of the 

 stem cut out from one side to 

 the other. The scion is cut 

 to fit this opening, and it is 

 inserted as in the figure, and 

 bandaged in the usual manner. 

 Herbaceous-grafting An- 

 nual or Perennial Plants (fig. 

 220). The period chosen for 

 this mode of grafting is that 

 of the greatest vigour of the 

 plant, that is, some days before Herbaceous - grafting 

 its going into flower. The stem of the stock is cut ^ ."*?** having 

 through above a leaf, as near as possible to its petiole, oppot ve *' 

 and a slit downwards is made in the section. A shoot is then taken off
