Growth Stages

Establishment

3-6 months

Young tree with limited branching and small canopy. Graft union clearly visible. Roots establishing in soil.

Stake tree for support. Water regularly to keep soil consistently moist. Prune only to remove damaged branches. Apply mulch. Avoid fertilizing in first month.

Vegetative Growth

12-24 months

Vigorous branch development with increasingly dense foliage. Glossy green leaves with strong growth flushes. No flowers yet.

Prune to develop strong framework and open canopy structure. Apply balanced citrus fertilizer monthly. Maintain consistent watering. Monitor for pests.

Flowering

2-4 weeks

Small white fragrant flower clusters appear in axils of leaves. Flowers are highly aromatic and attractive to pollinators.

Reduce nitrogen fertilizer to promote flowering. Maintain consistent watering to prevent flower drop. Do not prune during flowering. Pollinating insects will visit naturally.

Fruit Development

4-6 months

Developing fruits are small and green, gradually enlarging and changing color from green to orange-yellow over several months.

Thin fruit if overcrowded (space 4-6 inches apart) to ensure larger, quality fruit. Apply potassium-rich fertilizer. Continue regular watering. Protect from strong winds.

Harvest Readiness

2-4 weeks

Fruits reach full size and golden-orange color. Skin becomes thin and loose. Sugar content peaks. Fruits emit sweet fragrance.

Stop nitrogen fertilizer 6 weeks before harvest. Maintain moderate watering to concentrate sugars. Harvest when fruits separate easily from branch with gentle twist.

Harvest Tips

Harvest when fruits reach full golden-orange color, typically 7-8 months after flowering. Fruits are ripe when they separate easily from the branch with gentle twisting.

Do not force unripe fruit off tree as it will not ripen further.
