Planting fruit trees indoors provides both function and beauty. Not only will the green leaves, bright flowers and vivid fruits provide visual appeal, but the fruit can also be eaten and enjoyed once ripened. Though a wide range of fruiting trees can be grown indoors, certain types are better suited for indoor spaces, both in terms of size and care requirements.
Meyer Lemons
Meyer lemon trees are considered one of the most popular indoor fruit trees. The size of the Meyer lemon tree is well suited for indoor spaces, as it reaches a maximum height of approximately 5 feet. The Meyer lemon tree produces a large quantity of nice sized lemons. Unlike other citrus trees, the Meyer lemon tree doesn't require a long hot spell to sweeten the fruit. Because of this, Meyers lemons grown indoors are sweet and edible.
Grapefruit
Dwarf grapefruit tress can be grown indoors and provide fruit throughout the year. The Oro Blanco grapefruit does particularly well indoors. The tree was developed from a cross between a white grapefruit and a pummelo and produces sweet fruit. Oro Blanco grapefuit trees do not need to be moved outdoors or placed in a warm location.
Bananas
Banana trees also produce fruit year round and can be well suited for indoor growing. With high enough ceilings, regular banana trees will fair well indoors. For smaller spaces, dwarf banana trees are more appropriate. The Super Dwarf Cavendish is a small type of tree that produces miniature bananas. Banana trees are sensitive to temperature changes and produce slower in cooler environments.
Limes
Small lime trees, such as key lime trees are easily managed in indoor growing spaces. The lesser-known Kaffir lime is also well suited for indoors and its fruit is often used in Thai and creole dishes and can be used in meat dishes, sauces and drinks.
Papaya
With full sun, moderate fertilizer, regular watering and temperatures about 65 degrees Fahrenheit, papaya trees can also thrive indoors. Fruit on the papaya tree begins to appear once the plant has reached 1 to 2 feet in height. Once the fruit forms, it requires seven to eight months to ripen.
