I have a potted three-headed Dwarf Date Palm that is starting to look very thin, the frawns are getting brown spots, and not growing very long anymore.

I water and fertilize it regularly, however, I fear it might be root bound in it's current pot, and need transplanting to a large pot???

Anyone have any advice on how I should transplant this? Do you think it is suffering from being root bound, and will come back to life in a larger pot with new soil?

Any advice would be appreciated! :-)
