I unwrapped the Sabal minor last week. I had wrapped it with landscape fabric and stuffed this with dry leaves for insulation. I didn't want this to become a compost heap so I thought I better unwrap it. A few of the palm leaves that were pressed against the landscape fabric had frosted but the rest look fine. This plant is on the north west side of my house, and because of a neighbours large evergreen it gets maybe 2-3 hours of sun in late afternoon. This will help it avoid sunburn after being wrapped for four months.
