What kind of palm trees do you have? Most types grown in central TX can take temps below 25 unless you bought some of those ultratropical ones from the garden center. For citrus, tangerines are the hardiest of the widely eaten citrus, unless you live in the northern suburbs they should be fine unless an '89 type event comes along or you get a really early or late hard freeze (low 20s for an extended period). They can stand usually temps into the mid-to-upper teens in the middle of winter without serious injury (heck even people in Dallas have been growing them the past 5-8 years).
The winter climate of Texas fascinates me, probably since I've been growing subtropical plants since the '80s. I'm amazed at how the climate suddenly went from one extreme to the other after 1990
I don't know if I have Washingtonia Robusta or Washingtonia Filifera. Either way, I've had lower to mid 20s mornings and didn't wrap the trees, and they seemed fine. I got them at Walmart, for $5 each in small pots about 6 years ago, the price being so low the sun had faded the bar code labels too much for the scanner to scan. Manager was in a good mood, I guess. Fit in the backseat of my Buick. Now, the one in better light, in the front yard, has a 'trunk' about six feet high, and with fronds is about twice that tall. Pretty low maintenance, except for pruning off dead fronds, and I've only drawn blood through the gardening gloves a few times. The backyard one is a bit shorter, and the tree is somewhat bent, away from the fence that limits it sun exposure. (Planted it near the fence because of powerlines over the backyard). The fronds are in full sun during the day, I hope it bends back straight.
