When should one prune Phlox? Is the best time in the spring and should they be cut back to about six inches or about halfway down the plant?

Yes, you can cut the spent flower stems to the ground at any time, but you should generally wait until spring for pruning back the remainder of the plant, just prior to new growth, as this normally triggers the regrowth process. If it is ginning to look unsightly, however, it will not hurt to give them a light trim.
