How do you distinguish between different types of fruit trees? Well, that’s a pretty simple question. You look at the tree to see what kind of fruit is growing on the branches. Either bananas, or mangos, or papaya, or some other fruit. Well then, how can you guarantee that when you plant a fruit tree, you will be sure to eventually get the fruit you want—mangos, for example? Well, the answer is that you must be sure that you have the right kind of roots.
