The Lemon Lime Tree

The lemon lime tree is an incredibly unique plant. Either through grafting or just by planting two trees in the same pot, these plants combine both the delicious Meyer lemon and the classic key lime into one tree.

History of the Lemon Lime Tree

Humans first started cultivating citrus trees in South-east Asia thousands of years ago. From there, trees like the lemon lime tree spread throughout everywhere from Italy to California. 

The lemon lime tree is a unique combination of meyer lemons and key limes. These trees are happy to grow side-by-side in the same pot or be grafted together to form hybrids. Because growing them side-by-side is a relatively common practice, it’s likely that this practice has been going on longer than the current “cocktail tree” trend. 

Lemon Lime Tree Characteristics 

These trees have some pretty unique characteristics in that they are a combination of lemons and limes. 

They typically grow to 8-feet where they are kept pruned to that height. Like many fruit trees, it gets as wide as it is tall. 

The fruits are a combination of sweet meyer lemons and versatile key limes. These are either grown side-by-side in the same pot or combined through grafting one onto the other. The trees retain their individual characteristics even when combined through grafting. 

Planting Zones

These trees are restricted to planting zones 8 – 11 when grown outside. That limits them to southern and some coastal regions in the United States. Luckily, these trees do great indoors and on patios.

This extends their planting zones to 4 – 11 when grown indoors or on patios. The lemon lime tree is a great choice for people looking for an indoor fruit tree that is hardy and can handle a variety of climates. 

Size and Spacing

These are small trees inherently. While they can grow to the full size of either a meyer lemon or a key lime, they are usually kept pruned down to a comfortable 8-feet. The width of these trees, also when kept pruned, hovers between 6 and 8-feet. 

When it comes to spacing, you’ll want to keep them around 4-feet apart. They do much better in close quarters than other fruit trees thanks to their small size. 


The lemon lime tree is a self-pollinating fruit tree. 

This makes it a great choice for the home gardener and even growing indoors. It’s important to remember that you can help this tree pollinate by either moving it outdoors when it’s flowering or by doing it manually. This is done by cutting off a mature flower and rubbing the pollen onto all the other flowers on the tree. 

Tree Care

Caring for your lemon lime tree is very easy. These are hardy fruiting trees that are very easy for beginners to grow indoors. One thing to keep in mind is that they require lots of nutrients. Make sure to keep some fertilizer on hand if you want consistent fruiting. 

Here are some other steps you should keep in mind. 


These are full sun fruit trees. You’ll want to plant them outdoors on a southern-facing spot of land to maximize their sunlight and keep them warm. 

If they’re indoors, try to get them time outside on a balcony or patio during warmer months. When indoors, the lemon lime tree should be parked in a room that gets 6 to 8 hours of sunlight each day. 


Watering your lemon lime tree couldn’t be more simple. While other fruiting trees have complicated schedules or moisture content requirements, the lemon lime has a sure-fire way to check to see if it’s getting a little thirsty.

Simply check the soil three inches down. If it’s dry there, then it’s time to water. 


You’ll want to prune your lemon lime tree trees ealy in the spring. 

Besides the basic pruning for size and shape, you’ll want to pay close attention to any grafted areas if you have the grafted version of the lemon lime tree. 

Sometimes grafted sections can grow faster than their host plant. This can then pull nutrients away from the entire tree causing serious health problems. Simply make sure that grafted sections remain a similar size to their neighbors and you’ll be good to go. 

Diseases & Care

Molds, pests, and bacterial conditions are all potential threats to your lemon lime tree. 

The best way to prevent these diseases is to make sure your tree stays well watered, has the appropriate fertilizer, and gets all the sunlight that it needs.
