Well, Make Sure Your Palms Have Good Airflow...

I was unwrapping my Washingtonia robusta and saw that there was definitely green, then once the burlap came off I see this... You can literally see where it goes from cold burn, to healthy, to rot. The spear is still intact, so off to get Hydrogen Peroxide I go.

Thats why I prefer the circus tent. The only thing touching my palms is air. Not even the rope lights touch them (save for the livistona). I wish you the best of luck as I know that feeling as 2 of mine needed peroxide. Hope our palms pull through!

OUCH

But they're tough.

Let us know if it comes back. I had a Cocothrinax go all nasty, but still tough to touch and rooted in, and back it comes!

Here's hoping for the best for that palm.

.... all you can do now is treat & wait and see what happens. Good luck with it.. spring heat should help get it going again.

A heating cable.

Or rotted when the growth should have been somewhat ok, at the bottom.

That isn't rot or fungus, that is dead tissue due to cold.  I believe that green your are seeing is where you had that bundle up at the top that prevented the frond from getting too cold.   The worst thing about robusta (and why they are a solid zone 9 palm when young) is that they will elongate the trunk so much where the meristem is several inches above the ground but only has a 6-8" diameter trunk to insulate it.  I highly suggest you move some more of that heating cable closer to the base of the palm as you weren't too far off from death temp on that one.   Filifera will fatten up quite a bit adding additional insulation in conjunction to their increased hardiness as long as they are grown in full sun. Shaded filifera will stretch and significantly decrease their hardiness to cold.

    • How Many People Soak Their Seeds In Water With Some Hydrogen Peroxide?
      By PalmTreeDude
      How many people soak their seeds with a small amount of Hydrogen Peroxide in water? I never did it before so I am just now trying, but what do you soak your seeds In? The picture below are some date palm seeds, I soaked them the first day with just water, and for a few hours today they will be soaking with water and a tiny bit of hydrogen peroxide. 

    • What Palm Is This? (Seen In Video)
      By PalmTreeDude
      I was watching a video of a family that went to Palmetto State Park, Texas, and at the start of the video it shows them driving down the road at the park, and at the time 0:30 you can see a large Sabal palm off to the left side. I am really bad with Texas palms. Do you think it is a Sabal mexicana? Video link https://youtu.be/W4arW3KJUic
       

    • Native Palms In Snow?
      By PalmTreeDude
      With all the snow in the Southeast, has anyone seen or taken pictures of native stands of palms in snow? I am sure there are tons of Sabal minor covered in snow in both Carolinas and stands of Sabal palmetto covered in snow in South Carolina and Georgia, also Bald Head Island, N.C. 
    • Mexican Fan Palm Protection In Virginia
      By PalmTreeDude
      So my Mexican Fan Palm finally got beat up when we hit 19 degrees F one night last week. So it is time to start protecting it. I put a heating cable around it today (Low is 25 degrees F tonight, a tempature it has been through before and stayed 100% green.) and will finish the protection tomorrow. I need to buy some burlap to keep the heat in. I will likely cut all of the fronds except the center spear off when I wrap it. No other palms of mine are being protected at the time and have no damage.
