The methods of grafting are – 

1. Whip or Tongue grafting 

2. Wedge grafting 

3. Crown grafting 

4. Bud grafting

1. Whip or Tongue grafting: 

  • In this method both scion and stock are of similar thickness 5 -8 cm long cut is made in both scion and stock as shown in the diagram. 
  • After that, a V-shaped incision is made in the stock and a complimentary incision is made in the scion.
  • The two are tightly fixed and covered with grafting wax. 

2. Wedge grafting: 

  • This method is adopted when the diameter of both scion and stock is exactly the same. 
  • The V-shaped incision is made in the stock whereas wedge-shaped incision is made in the scion. 
  • The two are then joined together, tightly fixed and sealed with grafting

3. Crown grafting: 

  • This method is applied in the case where the diameter or thickness of the stock is many times more than the scion. 
  • The bark of the stock is cut through from the surface downwards to a length of 12 to 15 cm. 
  • A small branch of same species is incised and this is inserted into the slit in the bark and tied firmly. 
  • The wound is covered with grafting wax. 

4. Bud grafting: 

  • In this method, a T-shaped incision is made in the bark of the stock and a bud from a selected plant is inserted into the T-shaped slot and bandaged properly.
