Seed - the seed of species in this genus generally has a short viability and is best sown as soon in containers as it is ripe[
]. Remove the fruit pulp since this can inhibit germination[
]. Soaking the seeds for 24 hours in lukewarm water hastens germination[
], which can take 1 - 6 months at 20Â°c[
]. The germination rate of fresh seed is about 50%, falling to 25% for seed 6 months old, and zero for those 1 year old[
]. Stored seed should be sown as soon as possible in containers[
]. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions when 10cm or more tall.
