Young Sapling
Year 1-2Tree is 2-4 feet tall with thin branches and developing branch structure. Leaves are small and delicate.
Establish strong watering schedule. Use support stake if needed. Prune to encourage branching. Protect from harsh winds.
Vegetative Growth
Year 2-4Tree develops fuller canopy with increasingly dense foliage. Branches strengthen and thicken. Tree reaches 8-12 feet height.
Continue regular fertilizing with balanced citrus fertilizer. Prune to shape tree and remove crossing branches. Monitor for pests.
Flowering
Late winter to spring (4-8 weeks)Fragrant white or pinkish flowers appear in clusters along branches. Flowers are small but highly perfumed.
Ensure adequate water during flowering to reduce fruit drop. Do not over-fertilize with nitrogen as it reduces flowering. Avoid pruning during flowering.
Fruit Development
6-9 monthsSmall green fruits emerge after pollination. Fruits gradually enlarge and develop characteristic finger-like segments extending outward. Color remains green initially, then yellows.
Thin fruits if overcrowded to ensure larger fruit development. Maintain consistent watering. Provide balanced fertilizer. Protect from strong winds.
Maturity & Harvest
Variable; year-round in warm climatesFruits turn bright yellow and emit strong fragrance. Finger segments are fully extended and firm. Fruits are ready when they yield slightly to pressure and have strong aroma.
Harvest when fully colored. Handle gently to avoid damaging delicate finger segments. Fruits can remain on tree 1-2 months after ripening.

Harvest Tips
Fingered citron fruits mature 6-9 months after flowering. Harvest when skin turns bright yellow and fruit emits strong fragrance. Cut fruits with sharp secateurs rather than pulling. The entire fruit—zest, pith, and segments—is edible and valuable. Fruits can be stored at room temperature for several weeks or refrigerated for 2-3 months. Peak fragrance occurs within the first 1-2 weeks after harvest.
