HORTICULTURE FOR SCHOOLS 



budding in the laboratory by placing them in boiling water for an hour 

 or so and leaving them in water over night. On such prepared material 

 practice shield-budding and some of the other forms, keeping in mind 

 the essential points necessary for successful budding. Write an account 

 of what you did and illustrate with drawings. 



2. Budding nursery stock. 



Materials. Young nursery trees; string; budding-knife. 



Procedure. Bud the trees according to methods described in the 

 text. Keep a careful record of the growth of the buds. If nursery 

 stock is not available, bud upon willow or other available trees. 



EXERCISE III. Practice in grafting. 

 1. Bench-grafting in the laboratory. 



Materials. Grafting-knife; one-year-old seedling roots of apple or 

 pear (these may be obtained from nurseries); cions of last season's 

 growth of apple or pear; waxed yarn for tying. 



Procedure. Make whip-grafts during the dormant season according 

 to methods described in the text, grafting the cions desired on the roots. 

 The roots may be cut from two to six inches long and the cion should 



be long enough to make the total 

 length of the graft of convenient 

 length for planting later. Wind the 

 grafts with waxed cotton yarn. 



2. Cleft-grafting of nursery 

 stock. 



Materials. Seedling nursery 

 stock; grafting- wax; grafting-knife. 



Procedure. Cleft-graft the 

 stock low down inserting the cion 

 desired. Wax all cut surfaces 

 thoroughly. 



3. Top-grafting. 



Materials. Heavy grafting- 

 knife or grafting-tool; worthless 

 trees; mallet or heavy club; graft- 

 ing-wax. 



Procedure. If some seedling or 

 worthless trees four or more years 

 old are available, top-graft them 

 to desirable varieties according to 

 in this chapter. (Worthless trees in waste placea 



the stock. 

 methods described 



are good for class practice in top-grafting.)
