Establishment (Year 1-2)
12-24 monthsYoung tree develops root system and canopy structure; minimal or no flowering expected
Water consistently, protect from strong winds, stake if necessary. Apply balanced fertilizer monthly during growing season. Prune to establish strong branch framework.
Pre-Flowering (Year 2-3)
12 monthsTree grows larger with denser foliage; may produce first flowers but fruit set may be minimal
Continue regular watering and feeding. Reduce nitrogen in late summer to encourage flowering. Ensure adequate chill hours (200-300 hours below 45°F) in winter for flower initiation.
Flowering (Winter to Early Spring)
4-8 weeksSmall creamy-white flowers appear in large panicles; peak bloom occurs December-March depending on location
Maintain consistent soil moisture and avoid fertilizing during this period. Protect from frost if temperatures drop below 32°F. Pollination occurs via wind and insects; no hand-pollination needed.
Fruit Development (Spring to Summer)
8-12 weeksSmall green fruits develop after pollination; gradually increase in size with characteristic bumpy skin texture developing; color transitions from green to red-pink to deep crimson
Water regularly and deeply; maintain consistent moisture to prevent cracking. Apply potassium-rich fertilizer to support fruit development. Thin fruits if overcrowded to promote larger individual fruits (one fruit per 2-3 inches of branch).
Ripening and Harvest (Late Spring to Summer)
2-4 weeksFruits reach full size (1-1.5 inches diameter) and deep red color; flesh becomes fully sweet and juicy; seeds remain relatively small
Stop fertilizing; reduce watering slightly. Fruits are ready to harvest when fully colored and slightly yielding to gentle pressure. Harvest by cutting stem, not pulling fruit.

Harvest Tips
Souey Hong is a mid-to-late season variety (May-July in most climates). Fruits do not ripen further after harvest, so pick only when fully colored—deep crimson with no green areas. Gently twist and cut the stem with pruning shears rather than pulling to avoid damaging the branch. Harvest in the morning when fruits are cooler. Store at 40-45°F in plastic bags with holes for 2-3 weeks; do not wash until ready to eat. Refrigerate for up to 3 months; freezing maintains quality for 6+ months.
Fun Facts
- 🌱 Souey Hong is named for its characteristic 'sour-eye' appearance—the small seed creates a depression in the fruit that resembles an eye, which is particularly pronounced in this variety
- 🌱 Lychee trees can live 100+ years and some specimens in southern China are over 1,000 years old; Souey Hong is a superior modern cultivar originally selected in China and now grown commercially in Hawaii, Florida, and California
- 🌱 The bumpy, leather-like skin of lychee fruits is so distinctive that the word 'litchi' derives from the Chinese 'li' (rough skin) + 'zhi' (branch), and the fruit has been cultivated for over 4,000 years in China
