Q.Hibiscus plants
I am in the process of saving a Hibiscus. A client where I work was going to throw this out, and I decided to try to save it. I cut the branches down to about 6 inches because there was some green showing near the bottom. I live in Arkansas and we have temps that can range from over 100 in the summer and down to 20 degrees in the winter. I currently have the plant outdoors because the soil was so wet. I think she watered this too much. Can you give me some guidance?
I have no way of taking a picture at this time.

Trimming it back was a good idea because this helps with survival after transplanting. If you have not already transplanted the hibiscus, and wish to plant it in your yard, you can transplant in fall, as explained here:

If the hibiscus is not a hardy species, or if you don't know the species, you should use winter protection for the plant. Mulch over the roots to protect them, and consider protecting the branches (if they grow back by then) with burlap or a wire frame of leaves:
