I have one in Palm Springs and it is thriving in full sun and with extreme heat. They are quite common in the desert. They don't mind the heat and sun.

I am a palm grower from Europe, I found your contact on google because I am a bit desperate, I am writing to you if you would advise me on the proper cultivation of the Bismarkcia nobilis palm, I bought this palm this spring, it is about 1.5 meters tall, and because she already had a small pot, so I transplanted her into a big and deep pot, I fertilize the palm tree regularly once every 14 days with a special fertilizer for palm trees, and it also has enough moisture, but still my leaves are slowly drying out, even though it has two new leaves growing now, her next leaf is starting to dry, do you think this is normal??? I read somewhere that this palm tree doesn't like repotting, is that true? what is your experience with this palm tree? I would very much like to learn more about its cultivation, and if you are willing to tell me tricks so that this beautiful palm tree does not die, I will be very happy, I will also be happy for any advice on how to grow it. Thank you very much for your answer. Tomanec David
It was small and in a 5 gallon pot when I bought it. It took 4-6 years to get this big as seen in the video. I think it would grow faster if it got more sunlight. It receives some partial shade from a acacia tree above it.
They are drought tolerant once established. I haven't watered mine since October in Southern California. During the summer, I water them weekly and they are very happy.
