Satsuma
Citrus unshiu
treeSatsuma is a seedless mandarin orange variety known for its easy-to-peel skin and sweet, seedless fruit. This small to medium-sized citrus tree is more cold-hardy than most citrus varieties, making it suitable for cooler regions. The tree produces abundant, golden-orange fruit typically in fall and winter.

Establishment (Year 1)
12 monthsYoung tree develops root system and establishes canopy structure with glossy green foliage
Water regularly to keep soil consistently moist. Avoid heavy fruit-bearing in first year; remove most flowers. Stake if necessary in windy areas. Apply light fertilizer monthly during growing season.
Young Tree Growth (Years 2-3)
24 monthsTree develops stronger branch structure and fuller canopy; may begin light flowering and fruiting
Prune to establish open vase-shaped canopy. Allow selective fruiting. Continue regular watering and balanced fertilizer application. Monitor for pests and diseases.
Flowering
4-6 weeks (spring flush)Tree produces fragrant small white or pale pink flowers clustered on branch tips, primarily in spring with minor blooms year-round
Maintain consistent watering during bloom. Avoid spraying foliage with water during flowering. Provide balanced fertilizer with higher phosphorus. Trees generally self-fertile but cross-pollination with other citrus improves fruit set.
Fruit Development & Maturation
6-8 monthsSmall green fruits develop from fertilized flowers, gradually enlarging and turning golden-orange over 6-8 months
Thin fruits to one every 6 inches for larger, quality fruit. Maintain consistent deep watering during this period. Continue regular fertilizer through summer. Protect from harsh winds which can cause fruit drop.
Harvest & Post-Harvest
Ongoing harvest over 2-3 monthsFruits reach full golden color and sweet flavor; tree may have simultaneous flowers and mature fruit
Harvest when fully colored and slightly soft to touch (November-January typical). Allow 2-3 week rest period after heavy fruiting before next fertilizer application. Prune after harvest to shape tree and remove crossing branches.

Harvest Tips
Pick fruit when skin reaches full golden-orange color and fruit yields slightly to gentle pressure (typically November-January). Twist or cut fruit from branch rather than pulling to avoid damaging twigs. Satsumas reach peak sweetness after color develops; waiting until fully mature provides best flavor. Store at room temperature for short-term use (1-2 weeks) or refrigerate for up to 3 weeks.
Fun Facts
- 🌱 Satsuma oranges are named after the Satsuma Province in Japan where they originated centuries ago and remain a cultural symbol.
- 🌱 Unlike most citrus trees, Satsumas are notably cold-hardy and can survive brief freezes to 10-12°F (-12°C) once established, making them the most northern-growing commercial mandarin variety.
- 🌱 Satsuma trees can produce fruit within 1-2 years of planting if grafted onto established rootstock, making them faster-bearing than many other citrus varieties.
