Growing Conditions

☀️
Sun: Full sun, 6-8 hours daily; partial afternoon shade in extremely hot climates (over 95°F) can prevent fruit scald
💧
Water: Regular, consistent moisture during growing season and fruit development; reduce watering slightly in winter. Needs approximately 40-60 inches of annual rainfall or equivalent irrigation. Avoid waterlogging; drought stress during flowering can reduce fruit set.
📏
Spacing: 360 inches
📅
Days to maturity: 3-4 years from grafted sapling to first significant fruit production; full production at 5-6 years
🌱
Planting depth: Plant at same depth as root ball; graft union should be 4-6 inches above soil surface

Soil

Type: Well-draining, slightly acidic loamy soil with good organic matter content
pH: 5.5-6.5
Amendments:
Compost or aged manure Peat moss Perlite or coarse sand for drainage Mulch (3-4 inches) to retain moisture and regulate soil temperature

Growth Stages

1

Establishment (Year 1-2)

12-24 months

Young 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.

2

Pre-Flowering (Year 2-3)

12 months

Tree 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.

3

Flowering (Winter to Early Spring)

4-8 weeks

Small 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.

4

Fruit Development (Spring to Summer)

8-12 weeks

Small 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).

5

Ripening and Harvest (Late Spring to Summer)

2-4 weeks

Fruits 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.

Companion Planting

Plan your garden →

Plant with:

Avoid planting near:

Walnut trees (black walnut produces allelopathic juglone) Citrus trees (compete for similar nutrients and can attract common pests) Shallow-rooted plants in immediate vicinity (lychee roots extend widely)

Common Pests

  • Spray sulfur-based fungicides in late summer/fall before bud break; prune affected tissue; maintain tree vigor with proper nutrition

  • Remove fallen fruit regularly; use pheromone traps; apply spinosad or neem oil at fruit development stage; bagging individual fruit clusters provides mechanical protection

  • Increase humidity with irrigation; spray neem oil or horticultural oil; strong water spray to dislodge; avoid over-fertilizing with nitrogen

  • Apply horticultural oil spray; prune heavily infested branches; maintain tree health; introduce natural predators like ladybugs

  • Yellow sticky traps; neem oil spray; reflective mulches; encourage natural predators

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
