There is nothing quite like being able to enjoy your favorite fresh fruit that you can pick straight from your own garden.  Some fruits take years to mature, but others grow much faster. Here are five fast-growing fruit trees you can plant in your backyard for a quicker harvest. In the southern US, the climate is ideal for citrus trees, which can be grown and harvested within three years. Loquat fruit trees can be grown in warm or temperate climates and are fruit-bearing within one to two years.  Similarly, fig trees are also a suitable option in warmer climates, and you will begin to see the fruits of your labor within one to two years.  Dwarf peach trees thrive in mild climates or can be grown indoors during colder months, producing small, juicy peaches in under two years. Mulberry trees usually start bearing small, edible fruits in their second year, with harvests peaking during the summer months.
