GRAFTI.XG BY DETACHED SCIONS.

vigour, and would have become trees of twenty feet in length, before cuttings 

 had attained the height of three feet. 



662. Grafting the tree Peony on the roots of the herbaceous species is 

 performed from the middle of July to the middle of August, and will be 

 easily understood from fig. 216, in which a represents a triangular space in 



the tuber or stock ; 6, the scion, 

 the lower end of which is cut 

 so as to fit the cavity in the stock ; 

 and c, the scion fitted to the 

 stock. It is not necessary that 

 there should be more than one 

 bud on the scion, for which rea- 

 son the upper part of 6 might 

 have been iaserted in a, in the 

 cleft manner. The graft being 

 tied ^\iih. bast, and covered with 

 grafting- wax, the whole is in - 

 serted into a bed of tan, leaving 

 only about half an inch of the 

 scion above the surface. The 

 tubers throw out roots by the 

 end of September or the begin- 

 ing of October, and are tnen 

 taken up and potted, and placed

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

 Belgium : — 



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

 formed either with a growing shoot (fig. 217), or with a dormant eye, 

 as in fig. 218, The former mode requires no explanation ; by the latter, 



on the neck of a bar- 

 ren tubercle a small 

 hole is made, in which 

 the bud is inserted, but 

 in such a manner as 

 that its base shall be 

 perfectly on a level 

 with the surface of the 

 tubercle, and the 

 edges are covered with 218. veg.groftuuj 



grafting- wax. The tu- the dahUa on us 



bercle 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. 



664. Herbaceous wedge-grafting (fig. 219) is effected by paring the scion 

 into a wedge shape, and inserting it into a corresponding slit in the stock. 

 It succeeds well both with trees and herbaceous plants, more especially
