: It was in the twenties for five or six
: hours last night (or so the weather
: men warned) and I wrapped my seven
: foot diameter Cycas revluta in
: thermal wrap with a heat source. It
: looks like a large igloo on my front
: yard. I have had it since it was a
: one foot baby for ten years. This
: is the first time I wrapped it up to
: protect it and I hope I did enough.
: It is supposed to get cold again
: tonight then back up into the 70’s
: by Thursday. My question is how
: will I know if it made it through
: the freeze alright and will I be
: able to tell right away? If some
: leaves get damaged should I remove
: them or is there anything to look
: for or steps to take after I remove
: my plant from it’s temporary igloo?
: Thank you for your help!

If a sago is under a tree, and you have 23F for 10 hours, it still wouldn't burn the leaves, yet alone hurt the plant. If you cover the leaves with a blanket or frost cloth, then you should be just fine, leaves and all. If you ever get some damaged leaves but mostly good leaves, I would keep them on until new flushes of leaves come out. If your leaves were REALLY damaged, you 2would see an off color at once, but for slightly damaged leaves, it might take 2 to 3 weeks to see the full damage, but I am guessing, you are not going to have a problem. I had 25 last night, with 29 already at 9pm, and anything like a sago, and even way less cold hardy cycads like my huge Encephalartos whitelockii doesn't look like it is damaged at all, and I don't cover any of this stuff.
