Limes add a lively zest to lots of culinary treats, including drinks and desserts. Grow your own lime tree either outdoors in warmer growing zones or in pots near a sunny, southern-facing window. You’ll love the elegant look of a dwarf lime tree, and a crop of versatile fruit will sweeten your family’s diet.
Lime Tree Characteristics
Lime trees are generally small, shrub-like trees that are similar to lemon trees but with more spreading and irregular growth patterns. The lime tree is thought to be a native of Southeast Asia. It seems to have been introduced to the United States from the West Indies and Mexico, and today lime trees are cultivated throughout the tropical regions of the world. Lime fruit is smaller, contains more acid and has a thinner rind than the fruit of lemon trees. Like other citrus fruits, it contains excellent nutritional value and is one of the main dietary sources for citric acid and vitamin C.
How & Where to Plant a Lime Tree
Lime trees require full sun, and they will perform best if they receive southern sun. They require excellent drainage, as they will not tolerate standing water. Lime trees require consistent moisture, and these trees will drop their leaves if left dry too long. They are heavy feeders of fertilizer, so fertilizer applications every few months are recommended for best performance. Lime trees prefer temperatures over 50 degrees F. All lime trees grown in northern locations need to be containerized and brought inside in the colder months for successful lime production.
