Fig. 80. Side Grafting 



Side Grafting*. This is a form of whip grafting, but the stem is not 

 cut away completely above the point of union. A notch or slit is made in 

 the side of the stock, as shown in fig. 80 at a, b, and the scions are inserted 

 and tied. It will be noticed that horizontal or vertical shoots may be 

 grafted in this way, and after the new shoot has grown to a good length 

 the stocks may be cut off just above the 

 point of union. 



Herbaceous Grafting 1 . This is ap- 

 plicable to plants having non- woody stems, 

 and is practised only for the sake of curi- 

 osity. Potatoes have been grafted on 

 Tomatoes, and vice versa ; Cauliflowers on 

 Cabbages; Zonal Pelargoniums, Dahlias, &c. 

 It seems, however, to be of real value in 

 the Australian Glory Pea (Clianthus Dam- 

 pieri), which grows freely when grafted on 

 the stems of seedling Colutea arborescens, 

 but will often perish on its own roots. 



Coniferous trees have been grafted with young shoots in the forest 

 of Fontainebleau and other places, the 'modus operandi, as described by 

 Du Breuil, being as follows : " When the terminal shoot of the stock a 

 (fig. 81) has attained about two-thirds of its length, it is cut back with 

 a horizontal cut to the point where it begins to lose its herbaceous con- 

 sistence and commences to become woody. The young 

 leaves are cut off between a and d, a distance of 

 between 2 and 3 in., leaving, however, about two 

 pairs at the top d d, to attract the sap. Thus pre- 

 pared, the stock is split down the middle to the depth 

 of 1 in. or 1^ in. The scion 6 is cut wedge-shaped, 

 and introduced into the split, so that the commence- 

 ment of the cuts on each side of the scion may be 

 nearly 1 in. below the top of the stock. The scion 

 should be cut at the place where its consistence is 

 similar to the part of the stock where it is to be in- 

 serted. Its diameter ought to be as nearly as possible 

 equal to that of the stock. The graft being placed, 

 it is secured with coarse worsted, commencing the 

 tying at the top and winding it down to the lower 

 part. In the case of delicate species it is well to 

 wrap paper round the grafted part as a protection 



against the drying action of the sun and air. The shoots at c are then 

 broken at about | in. from their bases. Five or six weeks after grafting, 

 the cuts will be completely healed; the tie may then be removed, and the 

 two portions d furnished with leaves at the top of the stock should be cut 

 off", otherwise they might give rise to buds, which, in pushing, would weaken 

 the graft."
