Citrus 'Lime': Key Lime

Citrus x aurantiifolia, also known as Key Lime, is a vigorous large shrub or small tree that is best known for its green to yellow (when ripe) fruit that is very juicy and aromatic. It is native to the tropical regions of southeastern Asia, such as Malaysia and Indonesia. It was cultivated commercially in the Florida Keys in the 19th century, hence its common name that is still used today although there is little key lime production remaining in Florida. Key lime has glossy elliptical to oblong evergreen leaves, similar to the leaves of the orange tree. All parts of the leaves and fruit are used for cosmetic, medicinal and edible uses. The flowers are showy and fragrant. The leaves are fragrant when crushed.

Key lime should be planted in the warmest possible location in your landscape, protected from cold winds. It is hardy in zones 9-11. The plant grows best in light to medium textured soils that are aerated and have good drainage. The plant will not do well in heavy clay soil or soils that drain poorly.  Key Lime does not tolerate flooding and is sensitive to high salinity.

Key Lime requires full sun (6+ hours) for optimal growth and fruit production. It does not tolerate shade.

Key Lime typically needs deep watering once or twice a week (about 1 inch per week) to keep the soil moist but not waterlogged. Soil should dry out to a depth of 2–3 inches between waterings. Newly planted trees need more frequent, shallow watering until established. It is very drought tolerant once established. Do not overwater.

Pruning is only required to shape it, remove dead wood, limit plant size, or thin fruit. We recommend Bond Drop Forged Pruner.

Key lime should be fertilized sparingly. We recommend Espoma Citrus Tone.

Proper nutrition is important to the health of your plant and its longevity. To ensure your plant is getting the appropriate nutrition, use a fertilizer labelled for this tree type and apply according to the label.
