does anybody know how to propagate this tree from seed??
CLOSED: cucumber tree (magnolia acuminata)
I found this info. for you:
Seeds
Magnolias grown from seed often vary in crown structure, size, vigor, and flower and foliage characteristics. Seed-grown plants usually take much longer to flower than asexually propagated plants.
Magnolia fruits are 2 to 6 inches long and ripen in late summer to late fall. When mature, individual follicles in the fruit split to expose red or orange seeds. Fruits should be promptly harvested when seeds are mature. Alternatively, fruits with immature seeds may be ripened in a warm room. Seeds should be macerated in water to remove the red seed coat and fleshy pulp. Soaking macerated seeds in water for a few days may help in pulp removal. Freshly cleaned seeds may be sown right away but germination may be improved if seeds are stratified at 40°F for 2 to 4 months.
