Cultivation Tips
This species does well in most subtropical and tropical areas. Select a location that receives full sun, even when young. It is widely adaptable to a wide variety of soil types. Unlike most palms, these do not need good drainage and actually prefer a heavy clay soil with plenty of water in it. Water regularly, taking precaution not to let the soil dry out in between waterings. Feed regularly during the growing season with a high quality palm fertilizer. Mature trees withstand hurricane force winds, and also transplant very easily. Due to its striking appearance, fast growth rate and adaptability to a variety of conditions, it is extensively planted as an ornamental palm in Puerto Rico.
