Buying fruit from the supermarket is convenient, but nothing compares to the joy of growing your own in your own backyard. Keep in mind that the size of your yard has nothing to do with this.
Apple tree (Malus pumila) is versatile and easy to grow. Choose an apple tree that's right for your climate. Once established, apple trees require only fertiliser and pruning (via the National Park Service).
The mulberry tree (Moras spp.) has small, tasty fruits. These fruits aren't always fresh in the store, so growing them makes sense. Native to North America, mulberry requires less maintenance than other plants (per the University of Florida Gardening Solutions).
Peach (Prunus persica) should be in every yard. Commercial peaches have the most pesticide residue, according to the Environmental Work Group. Peach varieties include dwarf, container-friendly options. The PlantVillage says this fruit plant's bright pink flowers are also ornamental.
The apricot tree (Prunus armeniaca) is both beautiful and fruitful. Apricot trees are cold-sensitive and only bloom in warmer climates. Apricots bloom early in the spring as an ornamental plant (via PlantVillage).
The Fruitguys says there are two types of pears (Pyrus communis): European and Asian. Pear trees can grow quite tall in the right conditions, but there are dwarf varieties ideal for a garden or balcony. For cross-pollination, plant two pears with compatible pollen, says the University of Minnesota Extension.
The quince tree (Cydonia oblonga) is known for its ornamental qualities, but its fruits are delicious. This small tree is ideal for smaller gardens. The quince tree's spring flowers are white and pink. They're low-maintenance and great for beginners (via Portland Nursery).
Prunus domestica is a slow-growing tree suitable for most gardens. Buy a fruiting plum tree because some varieties only bloom. Since the plum tree blooms in spring, beware of temperature fluctuations, says the University of Minnesota Extension. Methley is pest-resistant.
Psidium guajava loves warm climates. It's a rare outdoor plant in North America, but it thrives indoors (via Ask IFAS at the University of Florida Extension). Short dwarf guava trees can be grown in pots and brought indoors when needed. They grow in most soils with little care.
