Propagation
We have no specific information for this species - the information below is a general guide for the genus.
Seed - best sown as soon as possible. It does not require pre-treatment, but it is recommended to soak the seed for 12 hours prior to sowing[
]. The seeds are sown in seedbeds, where they are covered with a mixture of sand and soil (1:1) or with a thin layer of sawdust[
]. Germination of fresh seeds is usually good and rapid. About two weeks after germination, when the seedlings are 5 - 6cm tall, they are potted up into individual containers about 15 x 23cm with good drainage holes at their base[
]. It is normally recommended to use a mixture of forest soil and sand (at a ratio of 3:1) as the potting medium in order to introduce the appropriate mycorrhiza to the roots. The seedlings are placed in 50 - 60% sunlight and watered twice daily[
].
Seedlings can be planted out when 30 - 40cm tall - harden the seedlings off in full sunlight for one month prior to planting[
].
