That doesn't sound good-dry/warmth is about all you can do for it.

Time will sort it out-Good luck!

We had a thread on this last month you can look for.
My wife's W. robusta that lives in a pot and spends winter in the dining room--and grew there--is now outside and the same thing is happening to it. I'll try to get a photo up this week. Rubbery, turning yellow, wilting. I've sprayed it with copper fungicide on the assumption it is a fungus.
It looks worse each day, so if anyone has suggestions, please share. --Erik

I also had a washy wilt and die this spring after growing in a pot for two years. It lived outside in the summer and in my living room in the winter. I noticed wilting of the lower fronds one by one until finally the spear died. I assumed it was fungal infection and sprayed with copper fungicide. So, I'd also like to know what happened.
Thanks, Allan S.

Root rot! http://www.using-hydrogen-peroxide.com/gardening-with-hydrogen-peroxide.html Once the fronds start to close like an accordian and become rubbery it is on it`s last legs. The soil needs anti bacterial- fungal treatment. Hydrogen Peroxide. Follow the the directions on the site. Hope this helps. It works for me.

I second root rot. Once it's treated heat will be it's new best friend.

Good luck,
Bill

John,
the wife's Washy is looking worse. She cut off most of the fronds today. What is left feels firm, but is yellowing.
I went to the peroxide link and it gave mixing regimes (e.g., put 1 Tbsp. of the 3% H2O2 into 1 cup water).
No application directions, however.
So, how many cups of this solution do we pour on a 15 gallon plant? Do we pour it right on the soil surface? Stir it into the soil? Do we pour any into the crown? Over the leaves or spear? We'd appreciate any advice as it looks worse each day.
thanks,
Erik
P.S. the smug husband notices that palms that spent the winter outdoors are looking better....

Erik sorry I didn`t clarify last time you asked about your Washy.I would use the 3% hydrogen peroxide.So one cup H.P. to one gallon water.I used three cups of 3%H.P. in three gallons standing water for a sick 15 gal. W. filifera last fall. I watered the soil till it ran out the holes twice in one week. I also hand sprayed the whole palm including the crown.The patient made a full recovery I`m happy to say. I now use hydrogen peroxide regularly on all my plants. Hope yours recovers as well.

John

Thanks!
I was worried about over doing it so I merely poured 2 cups of the solution called for around the trunk base.
I'll make up a much larger batch tomorrow.
