INLAY OR BARK GRAFTING

The grafts must be given plenty of sunlight if they are to 

 thrive. On large trees some branches of the parent stock must 

 be left for a time, but the tree should be completely reworked 

 as soon as possible and all surplus branches removed. 



Inspect the grafts frequently during the first season to 

 make certain that all cut surfaces remain coated with wax. 

 Another coating at the beginning of the second season is ad- 

 visable in case of large stocks. 



(h) Cleft Grafting Grape Vines. Grape vines already es- 

 tablished in the vineyard may be cleft grafted to other varie- 

 ties. Do the work in the spring before the sap has begun to 

 move upward, or if this is not possible, wait until the first 

 flush of sap is over. Keep the cions dormant until used. 



Shovel away the soil about the base of the trunk and saw 

 the trunk off about 2 inches below ground level. Since the 

 grape trunk will not split readily, saw a slot with a fine hack- 

 saw, about 1% inches deep, and pry it apart to receive the 

 cion. 



Prepare the cion just as for the tree fruits, and insert in 

 the same manner. If the size of the stock permits, insert two 

 cions. Tie with a few turns of soft strong twine. Do not 

 cover the union with wax or other preparation as air seems 

 essential to healing. 



Mound the soil up loosely about the cion, leaving one or 

 two buds exposed. If the mound becomes hard, or if it forms 

 in clods, remove it and hill over again as often as may be neces- 

 sary to keep a loose, open covering permitting the entrance of 

 air and the escape of moisture from the wound. 



Keep suckers off the stock. Unless roots are desired on the 

 cion, it will be necessary to hoe the soil away each year for 

 two or three years and remove with a close clean cut any 

 roots that may have formed on the cion below ground. 



Vines grafted in this manner should fruit extensively the 

 third season.
