Seedling/Young Tree
6-12 monthsSmall tree with tender leaves and a developing root system. Initial growth is slow to moderate.
Protect from strong winds and extreme temperatures. Keep soil consistently moist. Apply light, frequent fertilizer. Stake for support if needed.
Vegetative Growth
1-2 yearsTree develops more branches and foliage, becoming bushier and taller. No flowering yet.
Prune to shape the canopy and promote branching. Continue regular watering and fertilizing. Mulch around base to retain moisture.
Flowering
2-4 weeksFragrant white flowers appear in clusters, typically in spring. Flowers are short-lived but abundant.
Maintain consistent watering and avoid over-fertilizing with nitrogen, which reduces flowering. Protect from frost if temperatures drop below 50°F.
Fruit Development
3-4 monthsSmall green fruits develop from pollinated flowers and gradually enlarge over several months.
Thin fruit clusters to promote larger individual fruits. Continue regular watering and balanced fertilizing. Watch for pests.

Harvest Tips
Sweet limes are typically ready to harvest 7-12 months after flowering when skin color turns pale yellow or light orange. Pick fruits when they yield slightly to pressure. Harvest by cutting with pruning shears rather than pulling to avoid damaging branches. Fruits do not ripen further after picking, so allow full maturation on the tree for best flavor. Can store at room temperature for 1-2 weeks or refrigerated for several weeks.
