I bought that Bismarckia in a 7 gallon plastic pot at Home Depot for $25.00 about 12 years ago. I feed it 4 times a year with the UF 8-2-12 palm fertilizer made by Lesco. Even I am amazed at how well it is doing. By the way, if you are not using that fertilizer, you should. It has slow release nitrogen and potassium as well as good micronutrients including boron, etc. I am now using it on all of my landscape plants with good success.
Anna, when you move your palm in a few years, call me and I'll come up there with my camera.
