Key Lime Tree
Watering Requirements
Water weekly or once half the soil has dried out.
Sunlight Requirements
Thrives in full sun, needing at least 6 to 8 hours of direct sunlight daily to produce abundant fruit.
Humidity Requirements
Key limes love humidity just as much as they love the sun, thriving best when levels are around 50–60%, though they are resilient enough to handle levels as low as 40% without much fuss. The easiest way to keep your tree comfortable is with a humidifier, which creates a consistent 'microclimate' of moist air that helps your plant thrive year-round. Unlike misting, which only provides a temporary moisture boost, a humidifier maintains a steady, controlled environment that mimics the tree's natural habitat.
Pet-Friendly Plant?
No, use caution when placing this plant in homes with pets.

Frequently Asked Questions
What is the difference between a Key lime bush and a Key lime tree?
Both are the exact same plant, but they are pruned and trained differently! A bush is allowed to grow branches lower to the ground, creating a fuller appearance. A tree
(or standard) has been pruned to have a single, clear trunk with the
foliage and fruit-bearing branches concentrated at the top.

How long does it take for a Key lime tree to produce fruit?
Key limes are known for being prolific producers. Depending on the size, some may already be producing fruit when they arrive. Generally, you can expect a harvest within 1 to 2 years for most nursery-grown trees.

Are Key lime trees toxic to pets?
Yes, like most citrus trees, Key limes contain
essential oils (limonene and linalool) and psoralens that are toxic to
dogs and cats. While the juice of the fruit is generally safe in tiny
amounts, the leaves, bark, and skin can cause digestive upset or skin
irritation if ingested or touched.

How big do Key lime trees get?
When planted in the ground in ideal tropical
conditions, a Key lime tree can reach 6-12 feet in height and spread 4
-8 feet wide. However, when grown in containers, the tree’s size is
naturally restricted by the pot. You can expect a container-grown tree
to stay a manageable 3 to 5 feet tall, making it perfect for patios and
indoor nooks!
