About Finger lime
Microcitrus australasica, commonly known as finger lime or caviar lime, is a shrub or small tree native to the subtropical rainforests of Australia. It is notable for its elongated, cylindrical fruits, which contain spherical juice vesicles resembling caviar, offering a burst of citrus flavor. It is ideal for growing in pots on patios or as part of a citrus garden, adding an exotic and functional touch.
Native range
Australia, specifically in the subtropical rainforests of Queensland and New South Wales.
Care tips
It requires full sun exposure for optimal fruiting, although it tolerates some partial shade in very hot climates. Watering should be regular, keeping the substrate moist but not waterlogged, especially during flowering and fruiting. It prefers well-drained, slightly acidic soils rich in organic matter. Avoid frosts, as it is sensitive to cold, and inadequate fertilization which can affect fruit production.
