Grafted tomatoes are quite different from the average, regular tomato. Because each plant consists of two plants, fused together, they require some different care and in turn, they give different results.
Most fruit trees are actually a combination of two plants that have been grafted together. Grafting is the practice of joining two plants together permanently, so that they will continue growing as a single organism. To make a grafted fruit tree, one plant is selected for its roots and is called the rootstock. The other plant is selected for its fruit, flavor, ripening time, and chill hour requirements and is called the scion.
