Morinda citrifolia, commonly known as noni or Indian mulberry, is a tropical evergreen tree native to Southeast Asia and Australasia, traditionally valued in Pacific and Asian cultures for its medicinal properties. Seed germination is slow and variable, typically requiring 3-9 weeks with proper pre-treatment, and succeeding best in consistently warm, moist conditions with soil temperatures maintained above 24°C.
Before sowing
Seed coat softening through water soaking or mechanical scarification. Fresh seeds show germination rates over 90%.

What to expect
Tips
Use fresh seeds whenever possible for optimal germination rates (often exceeding 90%). Pre-treat seeds by soaking in warm water for 24-48 hours or mechanically scarifying to reduce germination time. Maintain warm soil temperatures between 28-35°C and avoid cooling below 24°C at night. Cover seedlings with transparent lid or plastic wrap to retain humidity, ventilate daily to prevent mold. Once seedlings develop 2-4 true leaves (approximately 10-15 cm tall), transplant into individual pots with compost + sand + garden soil (1:1:1 ratio). Gradually acclimate seedlings to direct sunlight over 1-2 weeks before moving to permanent location. Keep soil consistently moist but well-drained; avoid waterlogging.
