Planting & Growing Guide

When to Plant:

• Best Time: Fall or early spring for natural cold stratification
• Cold Stratification Required: 60-90 days to break dormancy

Seed Preparation:

1. Seed Cleaning: Remove the outer red seed coat if still present.
2. Cold Stratification:
   • Mix seeds with moist sand or peat moss in a sealed plastic bag.
   • Store in the refrigerator at 34-40°F (1-4°C) for 2-3 months before planting.
3. Soaking (Optional): After stratification, soak seeds in warm water for 24 hours to enhance germination.

Sowing Instructions:

• Planting Depth: Sow seeds ½ inch deep in well-draining soil.
• Spacing: 10-15 feet apart for full tree growth.
• Watering: Keep soil consistently moist but not waterlogged.
• Temperature: Maintain soil temperatures 65-75°F (18-24°C) for optimal germination.

Germination & Growth:

• Germination Time: 1-6 months due to dormancy period.
• Seedling Care: Protect young plants from strong winds and extreme heat.
• Transplanting: Once seedlings reach 12 inches tall, transplant to a permanent location.

Care & Maintenance:

• Watering: Regular watering, especially during the first few years. Avoid letting the soil dry out completely.
• Fertilization: Use a slow-release, balanced fertilizer in early spring.
• Mulching: Apply organic mulch around the base to retain moisture and regulate soil temperature.
• Pruning: Minimal pruning needed—remove dead or damaged branches in late winter.
• Pest & Disease Control: Generally pest-resistant, but monitor for scale insects and leaf spot.

Blooming & Enjoyment:

• Flowering Period: Late spring to early summer (blooms appear after several years of growth).
• Fragrance: Sweet, citrus-like scent.
