ORGHPS Germination Guide: Requires scarification. Nick or rub between sheets of sandpaper. Requires soaking. Place in warm water until seeds swell, usually 24-48 hours. Discard water and any seeds that remain floating. Pulpy coat inhibits germination. Remove by soaking and rinsing in clean water for approximately 7 days. Discard water. * soak in hot water for 24 hours to scarify; plant at 32°C for 2-3 weeks, then 4°C for 4 months
