Lemon and lime trees are small to medium citrus trees. They grow well in sub-tropical and tropical climates and cannot withstand frost or freezing temperatures. Lemon and lime trees grow best in loose, well-draining soil and full sunlight. The best time to plant is in September or October after the heat of summer has passed and the rains are approaching. A well-established lemon or lime tree will produce prolifically for 10 to 15 years.
Dig a hole that is twice as wide and as deep as the nursery pot in which your lemon or lime tree is growing. Break up the soil in the bottom of the hole using a shovel or garden fork.
Turn the tree onto its side and, grasping the base of the trunk, gently wiggle it free from the container. Gently unwind any roots that are wrapped around the root ball.
Place the sapling into the hole so that the base of the trunk is level with the surrounding soil. Spread out any roots that you unwound from the root ball.
Fill in the soil around the root ball a few handfuls at a time, patting it down as you go. Add a total of 3 gallons of water by applying a little after each few handfuls of soil.
Build up a 6-inch mound in a circle around the edge of the planting hole. This water ring will hold water and channel it down to the root system.
Water two or three times a week until the tree begins to put out new green growth. Then reduce watering to twice a week for the next three to five weeks. To water, fill the water ring around the tree.
