if the root ball is a solid cube with almost no soil left, then potting up sounds like a good idea... I would NOT remove the remaining soil from the rootball. Palms do not like their roots disturbed. Best to just plop it in a larger pot and surround it with potting soil. But if rootball is not a solid cube, you do not have to pot it up... drainage would be nice, though.

Thanks, with infinity better drainage i will be able to flush the roots, should I water to wet the soil then after afew minutes poor about a pint of water through at a time leaving a few minutes between to drain then fertilize on the next water time? Or would there be a more specific method?
