Finger Lime - Botanical Facts and Properties
A unique citrus gem
The finger lime, scientifically known as Citrus australasica, is a unique member of the citrus family. Native to the rainforests of Australia, it is often referred to as the "caviar lime" due to its unique pearl-like fruit (vials). These trees, which can reach heights of 2 to 5 meters, bear elongated, finger-shaped fruits that are usually 5 to 10 centimeters long. The rind of the fruit varies in color, from green to brown to purple, depending on the variety.
Leaves and flowers
The leaves of the finger lime tree are small and shiny, elliptical in shape, and emit a fragrant citrus scent when crushed. The tree produces small, white flowers with a pleasant aroma, which usually bloom in spring.
Climatic preferences
Finger lime trees thrive in subtropical and tropical climates. They are sensitive to cold temperatures, with an ideal range between 10° and 30°. These trees require full sun exposure for optimal growth and fruit production.
pollination
Finger lime trees are mostly self-pollinating, but cross-pollination can improve fruit production. Bees and other pollinators are key to improving fruit development, so planting other citrus varieties nearby can be beneficial.
Cultivation, growing and care of finger lime trees
When planting caviar lime trees, it is important to choose a location with good drainage. The soil pH should ideally be between 5.5 and 7.0, slightly acidic to neutral. Make sure the planting hole is large enough to accommodate the root system without crowding.
Site selection and soil preparation
Choose a location that receives full sun and is protected from strong winds, as these conditions are essential for fruit development. Adequate sunlight ensures that the tree's photosynthesis process functions optimally.
Watering, fertilizing and mulching
Proper watering is essential for finger lime trees. These citrus trees need consistent moisture to thrive. Water them deeply and regularly, but avoid overwatering. Fertilize the tree with a balanced citrus-specific fertilizer during the growing season.
Mulching helps retain soil moisture and suppresses weeds around the base of the tree. It is recommended to apply mulch 5-10 centimeters deep, making sure not to touch the trunk.
Pruning and pests
Pruning is essential to maintain the tree's shape and encourage air circulation. Remove dead or diseased branches, and prune back any new trunks (called "suckers") that try to grow from the bottom of the tree.
Finger lime trees can be susceptible to pests such as aphids. Regular inspection and application of organic pest control methods can help protect the tree.
