ORGHPS Germination Guide: Sow @ 4°C for 3 weeks, then place at 20°C. Requires light or the seed is very fine. Surface sow and expose to light. Requires soaking. Place in warm water until seeds swell, usually 24-48 hours. Discard water and any seeds that remain floating. * sow fresh or soak old seed; prechill 4 weeks or place outdoors over winter and bring indoors once germinated to avoid temperature shock; transplant at 4 leaves
