Establishment (Young tree)
1-2 yearsSmall grafted tree with developing root system and initial canopy formation
Plant in spring for best establishment. Stake if necessary for support. Remove competing shoots. Water consistently. Delay fruiting to encourage strong growth.
Vegetative Growth
1-3 yearsTree develops strong branch structure and foliage canopy; no flowering yet
Prune to shape tree and encourage branching. Apply balanced citrus fertilizer monthly during growing season. Maintain consistent moisture. Monitor for pests.
Flowering
2-4 weeksFragrant white or pale pink blossoms appear in spring; flowers last 1-2 weeks
Ensure adequate watering during flowering. Do not over-fertilize with nitrogen as it reduces flowering. Minimal pruning during this period. Protect from late frosts.
Fruit Development
4-6 monthsSmall green fruits develop after successful pollination; gradually enlarge and change color
Thin fruits to one every 6 inches for larger, quality fruit. Water consistently and deeply. Apply potassium-rich fertilizer. Monitor for fruit flies and scale insects.
Maturation & Harvest

Harvest Tips
Harvest fruit when fully colored (orange-yellow) and slightly soft to touch, typically 10-12 months after flowering. Citrus fruit ripens on the tree; harvest by twisting gently and pulling, or cut with pruning shears to avoid damaging branches. Fruit can be stored at room temperature for 1-2 weeks or refrigerated for 4-6 weeks. Best flavor when left on tree until fully mature.
