Pygmy date palm hit by freeze
We had a week of at or below freezing temps 2 weeks ago, including two days where overnight temps were in the mid to low 20s. This is very unusual for Houston.
I wrapped the base of my large potted pygmy date palm the first night, and saw in the morning it had ice on the fronds. They were still green, and it melted off by the afternoon, but two nights later there was another freeze. I covered the entire tree the second time (bedsheet with a plastic tarp, knotted around the whole tree, like a big lollipop.
The fronds did not get iced this time around, but the fronds are all quite brown. I was at first concerned that the tree had been done in and if I understand it correctly, browned fronds do not return to green.
However a closer look shows green at the base of the fronds (where they meet the trunks) and the trunks themselves are not mushy. I did water the plant well the night before the freeze, and again after we no longer had freezing temps.
Here are two pictures of the tree today and one from last summer. One shows the overall tree, and one shows the green parts up close.
I'm now fairly sure that the tree is alive and will recover, but I'm wondering what to do about the brown fronds. Is it correct they won't return to green? If so, I'm thinking that a trim or prune is in order, but this is my first palm so I have no idea how/when to go about that, and what to expect for regrowth (timewise and looks-wise).
