info		 This palm appreciates consistent water, but doesn’t want to have soggy feet. Once it’s established, be sure to water it when the top inch or two of the soil is dry. Usually this will mean watering deeply every five to seven days during the dry season. Planting this palm with good drainage will help to make sure it doesn’t accidentally get overwatered.

Growing Notes

This solitary palm will grow only one trunk during its lifetime. If you have a pot with multiple trunks in it, that’s because multiple separate palm trees were germinated in the pot. The good news is that you won’t need to thin out suckers over time to maintain the number of trunks you started out with.
Once it’s mature, this palm will naturally shed its leaves, leaving the trunk below the palm’s crown exposed. A great choice if you’re looking for a palm with a clean trunk but don’t want to deal with manually removing the leaves.
Palms are generally heavy feeders, so if you want them growing quickly and looking their best, they should be fertilized at least three times a year. Fertilizing at spring equinox, summer solstice and fall equinox will allow for a winter rest. Be sure to feed your palm with a fertilizer that contains micronutrients, especially if you see yellowing leaves or yellow spots on the leaves.
This palm jumps up quickly, being very fast growing but also relatively short lived, lasting only a few decades before it blooms and dies. They are technically “hapaxanthic” meaning that individual stems bloom at nodes almost all the way down the trunk before dying.
Avoid particularly windy locations, as the leaves are unsightly with consistent wind.

Special Interest

This palm’s juicy lush look is an absolute must-have when creating a tropical garden in a temperate climate. Mix it with other broad-leafed flowering plants like cannas, hedychiums, philodendrons, or monsteras.
