Growing fruit trees indoors allows you to grow your own fruit, such as lemons, limes, grapefruits and bananas, regardless of your climate. Indoor fruit trees are usually also very ornamental, smell wonderful, help purify the air, and give you the assurance of healthy fruit free from unwanted chemicals or pesticides. Not all fruit trees are suitable for growing indoors, however. Dwarf varieties of citrus, and those that don't require massive amounts of sunlight to set and ripen fruit, are the best fruit trees to grow indoors.
Dwarf Meyer Lemon
One of the most popular fruits to be grown indoors, the Dwarf Meyer Lemon produces edible fruit, often in large quantities. It is also ideal for indoors, because unlike some citrus varieties it does not require a lengthy hot spell to sweeten the fruit.
With beautiful leaves, edible fruit and uses for most of its parts, including the rinds and leaves, the Kaffir Lime is well-suited to growing indoors. This lesser-known lime variety is often used in Thai and creole dishes, but it's also handy for use with meats such as fish, chicken and pork, in sauces and in drinks.
The juicy and delicious kumquat does well indoors if the plant is dwarfed or pinched off to limit its height. The fruits are both ornamental and delicious.
Oro Blanco Grapefruit
Developed as a cross between a Duncan grapefruit and a pummelo, the Oro Blanco Grapefruit grows well indoors and will produce sweet fruit without being placed outdoors or in a warm location.
Super Dwarf Cavendish
The Super Dwarf Cavendish, also known as Novak, is a small banana tree that grows well indoors and produces edible miniature bananas. They are sensitive to sudden temperature changes, however, and may produce fruit slowly if temperatures are cool.
