Based on your location, both should go outside already. I am in Atlanta and all my trees have been out for a couple weeks. The Fukiens can take temperatures down to about 45 or so, assuming no high winds or rain (at least mine do). Ficus' tend like it warmer though, so I generally watch them below 50. My Chinese Elms are always outside. I always have pine straw handy in the wintertime to throw on my trees, but haven't used it the last two years. Chinese Elms can take pretty low temperatures. I am in Atlanta though, but SC is generally around the same climate, often warmer. I believe Ron Martin is from SC, he may be someone to talk to... Either way, your elm will be plenty fine outdoors all year, and right now, the Fukien can go out too. Keep an eye out for pests on the Fukien though, they are a pest haven. I use a spray bottle of soapy water and spray all my Fukiens (only have 3) once a week to keep away the pests. Most will say to wait, but I am cautious like that and have had no problems in the last year and a half of doing so... If Fukiens were outdoor trees, I would have 10-15 of them. I love them and the way they grow... Elms would easily be my 2nd favorite along with Black Olives/Azaleas...
