Germination Without pretreatment (scarification) the seeds normally germinate within six weeks whereas extracted seeds only need one week to germinate. If facilities are available, stratification in sand for 60-90 days at 5 deg. C is recommended. Seed should be sown in trays or beds, and the seedlings pricked out when 2 pairs of true leaves have developed. The seedlings should also be given full light. It is likely that seedlings will need about 15 months in the nursery. Scarification / Stratification Scarification, extracting the seed from the stone, and treating it with sulphuric acid has also been recommended. To germinate, seeds need full sunlight. Germination is epigeal and takes 3-4 weeks with seed left in stone, quicker if it is cracked, and 1 week if carefully extracted.
