Grafting is the act of taking off a limb off a tree/plant and taping it on on another tree/plant of the same family to have more than one fruit/vegetable growing on the same plant. In other words you put the tissues of two plants together to make it grow more stuff. This is a video of Anya and i doing rad stuff in our grafting adventure. If you look far back on the science blog you can see a post on a tree that bears more than 40 fruits.
