With freezes pushing into south Texas as early as November and Monday's well-publicized deep freeze I know some of you are wondering about the Bismarck Palms in the front yard. There is other news to report on the state of the garden but I'm pretty sure you'll want me to just cut to the chase here.
The low overnight Monday to Tuesday was 20.8 degrees F/-6.2C . The worst part is the cold stuck around to keep the temps below freezing well into early afternoon. With the previous days being cold and cloudy I'm sure the ground did not warm up during the day either so we wrapped the trunks of the Bismarckia nobilis with lights and puddled extra lights around on the ground to keep the shallow roots warm. There wasn't any way to cover a palm in the winds which blew in ahead of the latest front.
I'd say the palms look pretty good overall considering how cold it was. Some of the older outside fronds display tip burns from the weeks of cold weather we have been experiencing. It's taken on a distinctly violet hue with the cold.
The palm on the north side of the yard which was antlered by the deer a while back is still recovering and looks to quickly lose a few more fronds.
Some of this damage was due to deer but this one doesn't look as good as the other.
It might take a few weeks to know if there was damage to the roots on either plant.
When I decided to push the edge with these plants I knew there would be weeks like this and this isn't even the coldest weather we've experienced in the last few years. We'll see whether the root warming approach can keep these going here over the long term.
