GRAFTING | éi 
Root-Grafting. 
This is practicable with many plants, either on their 
own roots or on those of others, and a larger stock is 
obtainable of such as succeed than by any other method. 
Good roots should be secured as stocks when the plants 
bearing them are in a dormant state, and the graft 
inserted, in most cases, when the sap begins to flow in 
spring. Large, fleshy roots, such as Dahlias and Tree 
Pzonies, should have a notch cut in a triangular form, 
about 14 inches long, and the shoot or graft similarly 
prepared and made to fit therein (see illustration). 
Other plants largely propagated by root-grafting are 
Bignonias, Clematis, Hollyhocks, and Wistarias, Saddle- 
grafting on roots is sometimes employed.
