If it's your first time growing fruit trees, you might be surprised to find out that almost all fruit trees are grafted, meaning they are actually TWO fruit trees! The first is the rootstock, which is below the soil. Rootstocks can have different properties, most commonly height - dwarf, semi-dwarf, and standard. Then, you have the fruit you actually want to grow, which is grafted TO the rootstock and grows above ground. The problem happens when the rootstock starts to grow shoots ABOVE ground.
