Tongue or whip grafting is 



used with seedlings as stocks, the 

 stock and cion being of the same 

 thickness. The stock is cut off with 

 a long slant, the cion is prepared in 

 the same manner. A longitudinal cut 

 is made in each so that when the 

 cuts are opened the stock and cion 

 wiU fit exactly in their places. A little 

 practice will show where the tongues 

 should be made. The graft should 

 be wrapped with waxed string, which 

 is made by soaking a ball of No. 18 

 knitting cotton in grafting wax. This 

 method is'employed especially upon 

 roots of seedling fruits and upon the 

 more slender twigs of trees. 



Saddle grafting. In this case 

 that part of the stock on which the 

 cion is to be placed is cut to a wedge 

 shape. A neatly made notch is cut 

 in the bottom part of the wood of 

 the cion to fit closely over the wedge- 

 shaped part of the stock. Tie the 

 stock firmly with waxed string. This 

 method is used in grafting Rhodo- 

 dendrons. 



Crown grafting is performed by heading back a large-sized 

 stock, making an incision in the bark from the severed part down- 

 ward. Raise the bark on each side of the perpendicular cut, as in 

 budding; make a slanting cut on one side of the cion, and insert 

 beneath the bark; bind together and cover with grafting wax. 



Veneer grafting is principally practiced on coniferous plants 

 and Rhododendrons. It consists of making a cross cut through the 

 bark and slightly into the wood. A short distance above this cross 

 cut begin with a slanting cut downward until the first cut is reached; 

 shape the cion so that it fits exactly; tie in position and cover with 

 wax. The stock is headed back after the union has taken place. 



Inarching consists of uniting the cion to the stock while it is 

 still supported by the parent root. It is the simplest of all the 



Fig. .'i-Wmp or Tongue Grafting 

 In grafting the stock and cion 

 must be firmly bound around with 

 broad raffia or other ligature. The 

 above drawing is intended to show 

 how to fix the graft, but the binding 

 must cover the union thoroughly 

 to exclude the air.
