There is nothing quite as delicious or refreshing as a wedge of a juicy orange, a cool drink of homemade lemonade or a luscious bite of a rich key lime pie. If you want the freshest citrus by growing your own fruits, however, you need to know just how to care for citrus trees to keep them healthy and productive. Citrus trees have very specialized needs and won't thrive in just any climate. They prefer semi-tropical areas with plentiful sun, and can grow well outdoors in Florida, southern Arizona, southern California and along the Gulf Coast from Alabama to Texas. Slightly north of their native range, smaller citrus trees can still do well in greenhouses, and dwarf versions can be great additions to indoor landscaping in containers just about anywhere.

Caring For Indoor Citrus Trees

The popularity of citrus continued to spread as it was introduced on all continents. Today, the sweet orange Citrus sinensis is the most commonly grown tree fruit in the world.
Thus, in Missouri, sweet citrus trees tend to be difficult to grow and overwinter indoors, but can be moved outdoors during the warm summer months. In contrast, acid citrus species are easy to grow in containers inside and many will bear several crops of fruit per year if given optimum growing conditions.
Citrus trees grown indoors require a nursery container at least 14 inches in diameter with a loose, well-drained potting mix maintained at a 5. A half whiskey barrel also makes a good container, as long as it has drainage holes drilled in the bottom. Because citrus favor a sunny climate, the trees should be placed in a room kept at 55 to 68 degrees Fahrenheit with a southern exposure with at least 8 hours of bright light per day.
Trees also require high humidity percent. Because most homes have an average humidity of only 15 to 20 percent, a cool mist vaporizer or humidifier may be used to raise the humidity. Alternatively, placing the container on a pebble tray that is partially filled with water and misting of the foliage frequently helps raise the humidity. A soluble citrus fertilizer that is formulated to maintain the medium at a slightly acidic pH may be applied about once a month, or a slow-release fertilizer can be pre-mixed into the potting medium.
Trees require water when the top 2 or 3 inches of the potting medium feels dry. Over-watering is a common cause of fruit drop. Most citrus trees grown indoors are grafted onto a dwarfing rootstock such as trifoliate orange Poncirus trifoliata , Brazilian Sour, or Flying Dragon Hiryu.
While many citrus plants can be grown from seed, they tend to be large trees and may take more than 7 years to bear fruit. Because citrus trees are self-fertile, multiple trees are not required for pollination. However, if kept inside year-round, shaking the tree gently when flowers are open will facilitate pollination. Alternatively, pollen can be transferred from one flower to another using a cotton swab or small paintbrush.
There are many different types of citrus trees that can be grown indoors. For example, Calomondin sour orange is frequently grown as an ornamental with its fragrant while flowers and bright orange fruit resemble small tangerines even though its fruit is edible. Key or Mexican lime trees produce abundant, faintly fragrant flowers and that develop relatively small fruit. These limes are prized for their distinctive aroma and uniquely acidic juice.
Originally used in the famous Key Lime Pie of the Florida Keys southern Florida, it is often replaced by the juice of the Tahiti lime today. The Tahiti or Persian lime produces slightly purple-tinged flowers throughout the year, but most are produced in January. Tahiti limes are vivid green, but lack the bouquet of the Key lime. Trees produce thorns and the fruit has a bumpy rind. The leaves are used as a spice in cooking Southeast Asian dishes. Kumquat trees produce abundant fruit that are generally eaten whole, including the rind.
Meiwa kumquats are rarely found at the grocery store but are small, round, pale orange fruit with a sweet flavor unlike that of the more common Nagami kumquat that is tart. They are prolific fruit producers that are most often used for ornamental purposes. The limequat is a cross between a Key lime and a kumquat that was originally made inThese trees produce bright yellow fruit about the size of an egg.
The orangequat is a cross between the Meiwa kumquat and the Satsuma mandarin. The citrangequat is a cross of kumquat and citrange orange x trifoliate orange. The acidic fruit is like an oval kumquat and has been used to make marmalades. If you enjoy a beautiful plant, like an enticing floral scent, love to eat fruit, or enjoy using an unusual spice, there is a citrus tree for you that can be grown indoors with ease!

Urban Gardening with Drew: Growing Citrus Trees in Texas
Our aim is to impart the knowledge that we have gained over the years growing plants here at the nursery. Citrus plants are easy to grow. They will give you great pleasure with their deep green glossy foliage, exquisitely scented blossom followed by edible fruits. Citrus plants are happy to stand outside after the spring frosts have ended usually about the end of May. Plants should be placed in a shady spot and gradually crept into full sun over the course of a week or so to prevent leaf scorch.
Trees Planted Outdoors For the best production of blossoms and fruit, always plant lemon trees in locations that receive full-sun for six to eight hours each.
Citrus Trees as Houseplants
Although any citrus tree can grow in a container, full sized grapefruit or orange trees may be hard pressed to survive many years even in a large container. Look for dwarf varieties of citrus, such as 'Improved Meyer' lemon, 'Bearss' lime, 'Kaffir' lime, kumquats, 'Trovita' orange, 'Calamondin' orange, and 'Buddha's Hand' orange for container growing. These tend to stay between 6 and 12 feet tall at maturity outdoors and can be kept even at a smaller height in a container. In cold areas the 'Improved Meyer' lemon, 'Calamondin' orange, and kumquats are good choices since they're most likely to fruit indoors. Start with a small container when planting a young citrus tree since it will be easier to maintain proper soil moisture than in a big container. If the soil stays too wet in a large container, the young tree with a small root system may rot and die. A new citrus tree will grow fine in an 8-inch diameter container to start. Two to three year old trees will need a 10 to 12 inch diameter container. Eventually, you'll need a 16 to 20 gallon container or one-half whiskey barrel-sized container for long term growth.
