Establishment
1-2 yearsYoung tree focuses on root and canopy development with minimal fruiting.
Water regularly without waterlogging. Stake young tree for support. Remove any early flowers to redirect energy to growth. Apply mulch 3-4 inches from trunk outward.
Young Fruiting
2-3 yearsTree begins producing flowers and small clusters of fruit as it matures.
Allow limited fruiting; thin excessive fruit to improve size and quality. Continue regular fertilization with citrus formula. Maintain proper watering and mulch.
Flowering
4-6 weeksFragrant white blossoms appear in spring, typically March-May depending on climate.
Ensure adequate water during bloom. Do not over-fertilize with nitrogen as it can reduce flowering. Monitor for pests like citrus leaf miners and aphids.
Fruit Development
4-6 monthsFlowering subsides and small fruits develop; they gradually increase in size and begin color change from green to sunset orange.
Thin fruit if necessary for larger individual oranges (space 4-6 inches apart on branch). Continue regular watering. Apply balanced fertilizer monthly. Watch for splitting or cracking from inconsistent watering.
Ripening & Harvest
2-3 months (November-January in most zones)Fruits develop full sunset-orange color and reach full sweetness. Rind color is most reliable ripeness indicator for this variety.
Begin harvest when fruits are firm and fully orange-colored. Tree can hold ripe fruit for several weeks. Continue regular care. Prune after harvest if needed.

Harvest Tips
Sunset Oranges typically ripen November through January in most growing regions. Harvest when fruits are fully orange and firm with slight give when squeezed.
