Establishment
6-12 monthsYoung tree focuses on root development and branch structure. Foliage is light green and actively growing.
Stake if needed, keep evenly moist, remove early flowers to direct energy to growth, protect from extreme wind
Vegetative Growth
1-2 yearsTree develops dense canopy with glossy green leaves. Branches elongate and spread.
Prune to maintain shape, fertilize every 4-6 weeks during growing season, mulch to retain moisture
Flowering
2-4 weeksFragrant white blossoms appear in spring (March-April in most regions). Blooms emerge from branch terminals.
Maintain consistent watering, avoid excessive nitrogen fertilization which reduces flowering, pollinate by hand if needed indoors or in low-bee areas
Fruit Development
4-6 monthsSmall green fruits emerge and steadily enlarge. Fruits typically develop over 4-6 months.
Thin fruits if overcrowded to encourage larger individual fruit, maintain regular watering, provide balanced fertilizer
Ripening & Harvest
1-2 monthsFruits turn bright orange, develop sweet flavor, and become easier to peel. Ready for harvest typically October-December.

Harvest Tips
Satsumas typically ripen October through December. Fruit does not ripen further after picking, so harvest when fully colored and slightly soft to touch. Gently twist or cut fruit from branch, leaving small stem attached. Fruit stores 2-3 weeks at room temperature or 4-6 weeks refrigerated. Peak sweetness occurs after a light frost.
