Re: How do you graft a head of a plant and place it on roots and make it grow?

Grafting requires that the cambium of the two plant parts (the scion and the 
stock) be lined up so they grow together and their vascular systems connect. The 
pieces are often cut or shaped so they fit tightly together. The union of the 
stock and scion is usually covered with a special wax to prevent drying out. The 
stock and scion need to be from the same species or closely related species. You 
cannot graft just any two plant species together.
