Mulberry, fig, and peach trees are among the fastest-growing fruit trees, making them excellent choices for gardeners looking to enjoy homegrown fruit sooner. Mulberry trees are particularly vigorous growers, with some varieties growing several feet per year under ideal conditions. Fig trees, such as the Conadria and Brown Turkey, also establish quickly in warm climates, while peach trees can begin producing fruit within approximately 2–4 years after planting.

Keep in mind that fast growth doesn't always mean faster fruit production. The tree's variety, age, rootstock, sunlight, soil quality, and growing conditions all influence how quickly it produces a harvest.
