If you want to grow limes at home but lack the warm climate necessary for outdoor growing, take a look at dwarf lime trees. These plants remain compact, allowing you to tuck them into planters and grow them indoors. Join....

farmer Briana Yablonski to learn how to plant and care for these petite citrus trees.

During the dark days of winter, few things are as refreshing as savoring a piece of lime meringue pie or sipping on a tangy lime cocktail. While there’s nothing wrong with purchasing limes from the supermarket, growing your own limes at home brings a whole new level of appreciation for this tangy citrus fruit!

The tricky part of growing lime trees is their cold sensitivity. If you try to grow them outdoors in places like Pennsylvania or Colorado, you’ll watch them quickly succumb to winter temperatures. However, before you write off growing one of these trees at home, consider growing them in a pot indoors!

Dwarf lime trees remain less than ten feet tall, so they’re perfect for container growing and sunny indoor areas. Not only do they produce tasty fruit, but they also act as a conversation-starting houseplant! Stick with me to learn how to plant and care for these tiny citrus trees.
What Is It?
Unless you live in the warmest areas of the United States, you’ll have difficulty growing lime trees outdoors. However, if you live in zone 7 and colder, you can still grow these trees at home if you bring them indoors during the winter. Since smaller trees are easier to move and keep indoors, dwarf limes are a great option for northern growers.

The dwarf lime tree isn’t a specific species or variety. Instead, it’s any type of lime grown onto a dwarfing rootstock. The rootstock keeps the tree small and provides some disease resistance, while the scion determines fruit flavor, size, and production. That means you can find dwarf key limes, dwarf makrut limes, and dwarf Persian limes.

Characteristics
As I mentioned above, not all dwarf lime trees share the same characteristics. However, they do have many commonalities!

All max out between six and eight feet tall when grown in the ground. Container-grown trees remain smaller and typically grow four to six feet tall. Therefore, they’re a great option if you want to grow a lime tree indoors.

They are evergreen, so they keep their leaves year-round and never enter true dormancy. The leaves are oblong and may have a pointed or rounded end. Most of these citrus trees produce the majority of their small, white flowers in the spring, but flowers continue to pop up throughout the year.

The flowers eventually turn into small fruits that grow until they reach the size of a golf ball or a little larger. Most limes will mature and ripen sometime between early fall and winter.
Native Area
Lime trees are native to Southeast Asia. The exact native area depends on the type of dwarf lime tree scion. Regardless, all of these trees prefer warm tropical climates but tolerate indoor growing conditions.

Planting
Depending on where you live, you can either plant these trees outdoors in the ground or in a movable container. Planting these trees in pots allows you to keep them outside in the summer and move them indoors when colder weather arrives, but you can also keep them indoors year-round. Regardless of where you plant them, it’s best to start the planting process with a seedling.
