SCHOOL AND HOME GARDENING 



Pieces of the waxed knitting 

 cotton, eight inches long, will be 

 used to wrap around root grafts 

 and budded shoots, to exclude the 

 air from the wounds. Strips of the 

 waxed cloth may be torn in any 

 width desired and used in the same 

 way. Weak cotton and cloth are 

 Vised so they wUl not strangle the 

 growth which follows the grafting 

 and budding operations. 



8. Whip or Tongue Grafting. — 



Use willow or other convenient switches 

 to represent parts of the plant to be 

 grafted. These may be cut fresh from 

 trees in the garden or woods. With a 

 sharp blade, make outs as shown in 

 figure 93. The two pieces should be 

 fitted together as closely as possible, 

 as showii in the picture. The long, 

 sloping cut on each piece should be an 

 inch or more in length. This gives long 

 surfaces on the two while growing 

 together. After placing together, the 

 two parts should be snugly held by 

 wrapping well with waxed knitting 

 cotton. 



Between the bark and wood of 

 every woody plant is a layer of tis- 

 sue called cambium, or growing 

 tissue. If the canibiiun of the two 

 pieces is in perfect contact, growth 

 is likely to take place, otherwise
