Before sowing
Seed coat is extremely hard; pretreatment is essential. Without treatment, germination rates drop below 30%
Sowing
What to expect
Tips
Requires warm soil temperatures (minimum 70°F/21°C, optimal 75-90°F/24-32°C). Seeds germinate slowly without pretreatment. Use heated mat set to 27°C (80°F) for consistent warmth. Maintain high humidity during germination. Plant seeds 1 inch deep. Keep substrate moist but not waterlogged. Germination is slow and irregular, taking 7-21 days depending on conditions. Darkness or light is acceptable for germination.
