The Fruit Tree That Brings Tropical Aesthetics & Fresh Produce Year Round

Who doesn't love having a tropical vibe in their garden and patio? With the right fruit tree, you can have that aesthetic even in cooler regions. And even better, you'll also have plenty of tasty fruits to enjoy. One of the best fruit trees for adding both beauty and delicious produce to your garden is the lovely key lime (Citrus aurantiifolia). 

Native to Southeast Asia, key limes are only hardy in zones 9 and higher. You don't have to give up on your dream of growing these delicious citrus just because you live and garden in a colder climate though. Just grow your key limes in pots on your patio so you can bring them indoors during cold months. Growing a dwarf key lime tree that stays at a height of around 6 feet or less will make this easier, as otherwise a key lime tree can grow as tall as 24 feet. Whether you grow your key lime exclusively outdoors or bring it in to grow as an indoor fruit tree during winter months, its fragrant blossoms, and juicy fruit make it a must-grow. 

Regardless of whether you are growing your key lime in the ground or in a planter, it's important to provide it with well-draining, moist soil and plenty of light. Key limes need full sun to grow their best, and if you need to bring your plant indoors for winter, make sure you provide it with either a south facing window, grow lights, or both. While key limes don't require as much fertilizing as most citrus trees, they still benefit from occasional additions of a balanced fertilizer. Plants grown in containers generally require more frequent fertilizing. While key limes may require a bit of extra attention when grown in containers, potted citrus trees can thrive for years with the right care.

While mature key lime trees grown in-ground rarely need watering, younger trees and those grown in containers require more regular irrigation. Make sure to water your potted lime when the soil feels dry about 2 inches down. Young trees grown in the ground shouldn't go longer than a week or so without water.

To fully take advantage of the tropical vibe that key limes can lend, consider pairing them with similarly tropical looking plants. Even if you live in a chillier regions, there are plenty of cold-tolerant tropical looking plants that can bring a touch of summer to your yard or garden. Everything from passion flower vines to yucca are perfect for adding tropical flair to cooler climates.
