Cynthia,I do not have experience with Araucaria araucana, but I have a lot of
experience with Araucaria angustifolia, a native Brazilian pinetree. The tree
produces 6 inches in diameter balls that when ripe fall into the ground
spreading the acorns that have the shape of a spearhead with a lenght of 4cm.
After harvested the acorns need to be planted withing 6 months. Thereafter the
propagation rate falls in more than 40%. After one year it won't germinate any
longer. If you keep the acorns in the refrigerator, then the germination rate
won't drop so deeply. To plant this kind of acorn you just put them into black
plastic bags,with the arrow head of the acorn inside the pot soil. It is not
necessary to bury the whole seed. 30 days will be enough to see the seedlings
coming up.
This kind of acorn (Araucaria angustifolia) is edible and tastes great.
