cold protection for Queen Palms
I have several potted Queen Palms. I usually bring them in the garage when it is near 25F or less and have done well this way. I've got some 20F nights forecast, and occasionally I get down to 17F.
This year I am out of room in the garage and really need to find a way to keep these palms.
Can keep them outside, with protection?
A) how low?
B) what protection is needed?
They are 2-4' tall, about 5" diameter at soil line, and in 10-14" pots.
I have a small temp greenhouse. I actually don't know how to best use this, as it does not retain heat overnite. Does just keeping them sheltered help at all?
I was going to try wrapping the trunks with xmas lights, but not sure how many to use?
I've also got sheets and blankets, but not sure which is better, wraps or lights?
Or would I be better off booting my potted brugmansia from the garage and overwintering them in the temp greenhouse and using that space for the queen palms?
