If the ground will probably be freezing very soon I would personally wait until spring. You would probably find a lot of different opinions on the best timing, if the board was more active.

Thanks Jean & Peter.

I already decided to wait for spring to transplant my asparagus. We've abruptly had several consecutive nights approaching -10C and the (raised) bed doesn't get much daytime sun this time of year.
