How to Grow a Lime Tree Indoors


Lime trees are extremely cold sensitive and thrive in hot, humid conditions. But even for those living in areas that have cold temperatures, you can still have fresh limes by growing a tree indoors. With the sweet fragrance of spring flowers and the dark green foliage, indoor lime trees are a special addition to your home decor. Lime trees grown in containers will typically reach about 5 feet tall and small globe-shaped limes will be ready to harvest throughout the winter providing plenty of vitamin C and flavor to your diet.

Step 1

Place a layer of stones in the bottom of a 10- to 15-gallon container. This size container usually works well for a tree that is 3 to 5 feet tall. The container should have drainage holes and a saucer or plate in which to set it.

Step 2

Add a slightly acidic potting soil or peat moss-based growing mixture to the container, filling it about a third full. Water the soil well.

Step 3

Place the lime tree in the container and gently spread out the roots.

Step 4

Add more soil to the container. Tamp it down well as you add the soil in incriminates in order to eliminate any air pockets around the roots. Once the container is filled to the top with soil, tamp down firmly with your hands and water well.

Step 5

Water the lime tree every day to keep the soil moist, but without creating soggy soil conditions, which can cause root rot.

Step 6

Set the lime tree in a sunny location such as in front of a south facing window so that it receives at least eight hours of sunlight daily. If necessary, use overhead shop lights with 40-watt bulbs to create enough light for your lime tree to thrive.

Step 7

Maintain a temperature around 70 degrees Fahrenheit during the daytime and no lower then 50 degrees at night. If the temperatures drop below 50 degrees, the tree will not produce fruit and can die.

Step 8

Feed the tree every month with a high nitrogen fertilizer such as a 3-1-1. With such frequent watering, nitrogen is quickly leached out of the soil, so it's important to fertilizer lime trees regularly.

Step 9

Prune the periodically to maintain the size and shape of your tree. This can be done easily by pinching off new growth on the tips of the branches. Also cut off any suckers that grow up out of the soil from the roots.

Tips and Warnings

  • Do not let your lime tree dry out completely in between watering.
