How To Grow Malabar chestnut from seed

The Malabar chestnut is not a true chestnut but is related to the silk floss tree. It is native to Central America and northern South America. It is cultivated in many tropical regions, including Southern California. In the wild it is a tree that grows in freshwater swamps and alongside rivers.
The plant grows well in bright light, but also tolerates partial shade at room temperatures from 12 °C through 25 °C. A plant's leaves may turn yellow and fall when days are shorter in autumn which is not a sign of disease, and the plant will restart its growth without problem the following spring. A tree is mature when 4-5 years old. It produces its first fruit in spring and fall. Furthermore, it can withstand temperatures as low as 5 °C without losing its leaves, although people recommended not growing it below 12 °C as an orangery tree, the ideal culture temperature being about 20 °C all year round with high humidity. An occasional weak frost can cause it to lose its leaves, and it grows new leaves in the following spring.
