If just a single branch needs to be removed, you can do it any time. If the entire plant needs a trimming, late winter or early spring is the preferred time, with follow up done up until mid summer. Pruning tends to stimulate growth and if you prune in mid fall the new growth will not have time to harden before winter sets in. As winter approaches the growth rate will slow, so the problem shouldn't get much worse.
