Container patio and balcony gardens are becoming increasingly popular as people strive to feed their family healthier foods. Even people who don't have any type of outdoor space whatsoever are getting in on the trend by planting indoor herb gardens or using window planters for small vegetables. If you live in a luxury apartment, you too can grow healthy foods at home for your family. You can do so even if you don't have an outdoor space. And you may be surprised to learn that you can plant and care for a wide variety of plants, including citrus trees. Following are a few tips for growing citrus trees in your apartment. 

Select The Right Tree

All citrus trees are not suited for the indoors. Many varieties simply get too tall to grow inside, and some types of citrus trees don't do so well in an indoor environment. For these reasons and more, proper tree selection is vital for your success. Look for dwarf varieties of citrus trees when selecting your tree. Some common species that do well indoors include Valencias, Eureka Lemon and Oro Blanco, a type of grapefruit. 

Provide Lots of Sunshine

Your potted citrus plant will need a minimum of 8 hours of direct sunlight per day to thrive. If you don't get a lot of natural light in your apartment or if the light is short lived, you will need to provide supplemental lighting via grow lights. As a basic rule of thumb, if your citrus plant receives less than 6 hours of full sun, provide supplemental light. 

Humidify Your Tree

Citrus trees require a bit more humidity than many apartment environments can provide, especially during the winter months. If your apartment is dry, you can raise humidity levels with a portable humidifier. However, you should take care not to let humidity levels get too high. Humidity levels over 60 percent contribute to the growth of mold and bacteria. 

Water Only When Necessary

Only water your citrus tree when the top inch or two of soil dries out. Avoid giving your tree too much water as it can wreak havoc on your tree's root system. Keep in mind that indoor trees and plants do not dry out as quickly as outdoor plants. 

You can grow all sorts of things in an apartment -- including citrus trees -- if you don't have any outdoor space. The key to success is to select the right variety of tree. You should also take steps to provide the ideal environment for your indoor edible plants and trees to grow.
