Hello! I've separated palms like that at all times of the year. I prefer to do it when it is warmer because in my experience and the transplant establishes/grows quicker. I have done it in the winter here (we get very few freezes, zone 9a-b) and have just kept an eye on the transplant until it warms up. The guys I've grown are pretty resilient. If you are someone who will worry the whole winter, then wait until it warms up. If you can be relaxed about it, do it now. Good luck!
