Lime trees produce a small green fruit that is high in vitamin C, tastes sour and is acidic in nature. They prefer tropical and subtropical regions, but they can be grown indoors and in greenhouses in temperate regions.
There are four common varieties of limes: Mexican lime (also known as key limes), Tahiti lime (also known as Persian lime), giant key lime and Rangpur lime (typically used as root stock for lime trees).
Lime trees need to be planted on the southern side of your home for wind protection. The location should be sunny with well-drained soil.
Mature trees need to be watered every other week. Ammonium sulfate should be applied every four months as fertilizer. Mulch 1 foot around the base of the tree to keep grass from growing around the base.
Trees begin to bear fruit three years after planting. Harvest the fruit once the rinds begin to yellow. Fallen limes can be harvested and juiced. Freeze the juice for future use.
Lime trees are susceptible to stylar end breakdown, where juice pools in the blossom end of the fruit and causes it to rot. Asian leaf miners are also a threat to lime trees.
