I'd throw something over the queen leaves,just to keep cold from settling in the crown,the light helps but something over her keep some heat inside next to the crown,probably will fry the leaves anyway,being that cold.

My foxtail palm tapped out at around 28 degrees. I thought they were as hardy as the Queens but apparently no where close as all three of my queens still look great.

They say this second blast of cold air coming,will be colder than this cold blast!
17* here now,and we got about a inch of snow last night.

A sheet between the the leaves and plastic will keep the leaves from being damaged by contact with the plastic.
This will also increase the efficiency of the heat source and possibly keep the temp
down if you don't remove the plastic before the sun gets to warming it up in there. Good liuck

If you don't want to take the plastic off, a sheet or even a blanket over the top will be better too.

The two smaller queen palms I left totally unprotected seem to have survived just fine with us hitting a 15 degree low last night. I am really surprised how well all my palms have done in this cold. The Foxtail palm notwithstanding.

Plastic probably isn't enough, even with a light inside.

Sounds like your weather will stay cold for a while.

Have you got an old carpet, say 5x 8, that you could wrap around the palm, tied with bungee cords, then reapply the plastic over the top in case of more snow/freezing rain.

I'd be ripping the Christmas lights off the roof to put them around the plants 😆 😆
Good luck.

PS--I'm starting 50 Foxtail seeds. I could cry seeing your beauty shrivel in the cold.

It will take a little while, but queens can not take that kind of cold. You will see the fronds start to turn almost white soon. Mine burn in the lower 20's.

You're right, Jim.

The building inspector oughta be along any day now...

I don't think he will bother you if you-ahem- are sitting down and talking on the phone 😯 😆 😯 😆 😯 😆 😀 😯 😀 😯

I'll add a magazine holder... 😆

You were right Laaz. The unprotected Queens are turning white on the ends followed by brown then green closer to the trunk. Seem to be surviving but with pretty significant damage to the fronds.

Barb and others, I really don't understand the importance of adding sheets under the plastic. My little potted Washingtonias which I covered with plastic without a light look great. The plastic keeps the frost from building up on the fronds which seems to be all I need.

Fronds touching plastic is protection only from frost sitting atop the frond.
Anything cloth, like a blanket, has air spaces which won't transfer as much cold as plastic alone.

But blankets get wet, so plastic should be on top of cloth to keep moisture out.
Just a suggestion.

Good luck.
