Finger limes, are also known as “citrus caviar” to top chefs worldwide! These unique finger size pieces of citrus fruit are probably more familiar to our friends “down under” in Australia from where they originate. The small, round, firm, “pearls” of pulp inside the fruit do resemble caviar, and even burst open when bitten. They can and are used like caviar on top of sushi and is a favorite garnish topped on oysters. The lemon-lime flavor lends itself to many other recipes (i.e. cocktails, salads, curries,) as well as being used in marmalade. So the next time you want to make a big impression with your culinary skills, maybe you should... “let your fingers do the walking” with finger limes from Pearson Ranch.
Soil and fertilizer
They grow in a wide range of soils in tropical and subtropical rain forest. They are most commonly grafted onto exotic citrus with Citrus trifoliata being the most common and they are then particularly suitable for heavier soils. Grafted finger limes grow faster and withstand other climatic conditions because the grafted wood is usually taken from a mature tree. Like all citrus, finger limes prefer well-drained soil with a pH of between 6 and 7.
Mulch in spring and make sure the soil is kept moist in summer.
They require small amounts of fertiliser every 2 – 3 months. It is best to also give small quantities of soil conditioners like seaweed emulsion or worm castings regularly e.g. every 2 weeks.
Flowers and fruiting
The flowers are 10 to 14mm in diameter, white or pale pink and appear in late summer and autumn. They are followed by elongated fruits about 30-120mm long. The fruits ripen in winter through to spring and may be green, yellow, black, purple or red. The pulp is green, yellow or pink.
Propagation
Finger limes can be grown from seed, cuttings or grafting. They are slow growing and if grown from seed may take up to 15 years to mature. It is important to use fresh seeds. Semi-hardwood cuttings, like seedlings, are slow to grow and have a low success rate. Therefore, grafting on to Citrus trifoliata or a range of other citrus root stock is preferable.
Pests and diseases
The following practices can help limit the damage caused by citrus gall wasp: check your citrus trees between June and September when galls are at their most visible; prune off the infected branches by late August (before the adult wasps emerge); burn the infected branches. Do not put in the compost or green waste bin. Hang sticky yellow traps on the tree in mid-August as they attract and trap the emerging adults, but make sure you take the traps down by November as they also kill beneficial insects.
