Expert tips
The key tip
Microcitrus dreads stagnant water but loves regular watering: well-draining soil with thin mulch is ideal. Not demanding in nutrients if you add good compost upfront.
The common mistake
Too much winter watering can weaken citrus: in winter (December-February), water very sparingly, just enough to avoid completely drying out.
The pro's trick
Pinch back young plants regularly during the first two years to create compact branching before fruiting.
Care
Sunlight
Your finger lime thrives in full sun, with at least 6 to 8 hours of direct light daily. This exposure promotes abundant flowering and fruit production. In very hot climates, some afternoon shade can be beneficial in summer.
Watering
Keep the soil regularly moist without waterlogging. Water as soon as the soil surface becomes dry. During winter, space out watering but don't let the soil dry out completely. Adjust frequency based on climate and season.
Soil and planting
Prefer well-draining soil, slightly acidic to neutral, enriched with organic matter. A citrus or tropical fruit mix works perfectly. In pots, use a substrate specifically for Mediterranean or tropical plants.
Fertilizing and nutrition
Fertilize regularly during the growing season (spring-summer) with a balanced fertilizer or one formulated for citrus. Reduce applications in autumn-winter. An occasional addition of compost or enriched potting soil also naturally improves the soil.
Pruning and maintenance
Prune lightly after flowering to maintain a balanced shape and aerate the foliage. Remove dead or crossing branches. Moderate pruning stimulates branching and improves fruiting without weakening the tree.
Diseases and pests
Watch for spider mites, mealybugs, and whiteflies, which are common on citrus. Excess humidity can promote fungal issues. Inspect foliage regularly and treat quickly with soapy water if problems arise.
Did you know?
The finger lime gets its curious name from its tiny juicy pearls that burst in your mouth with a tangy flavor, resembling fish eggs. Native to Australia's tropical rainforests, this amazing plant produces miniature fruits (3 to 4 cm) that have won over modern and gourmet kitchens, where each bead is precious for garnishing dishes.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
