As long as the palms did not suffer from any sort of root rot or other disease that might have caused their death you should be fine. Roots and other plant parts are just organic matter and will decompose eventually.

I lost all 6 of my Queens last winter. They were all almost a foot in diameter, nice big trees. They had survived lows in the low 20's several times with fronds burning slightly but we had two arctic fronts in early January back to back with more than 24 hours of sub freezing temps. Five died. All 5 had spear pull. I don't think they can ever recover from pull. Only the largest one lived to put out new fronds in the spring but eventually died as well after putting out several stunted fronds. Lots of folks along the Gulf Coast have planted these palms over the last 10 years (during this stretch of mild winters) and thought they were at least zone 9 hardy, but sooner or later, we will have one of those bad winters where temps plunge into the low 20's for extended periods of time and realize these palms don't survive this kind of weather. You either replant them and expect to have to do this from time to time or go on to something else. Sadly, I think yours are gone. Steve

If you tug firmly on the spear and it stays put, it's still alive. If the palm is dead, the spear will pull right out with a sickening feeling of dead material. Sounds like it'll make it - but it's going to be in the ICU for a while. Lots of water (when warm, and drained well), heat, and light.

Hi Marissa Cass! The white stuff is mold. I would probably say that your palm is not revivable because it is beginning to rot. Don’t worry, majesty palms are notoriously difficult houseplants. I would recommend getting a parlor palm instead. They are just as beautiful as majesty palms, only much, much easier to care for. I can give you care instructions if you would like to purchase one. As for your remaining majesty palm, Costa Farms has an excellent care guide that might help you out a bit: A Guide to Growing Majesty Palms Indoors. I hope this helps! Good luck, damask_rose_5 : )
