Q.Can A Ming Aralia Be Submerged Before Repotting?
I just bought a new Ming Aralia and I wanted to transfer to a fresh larger pot I am wondering if I should submerge her to get out all the air and freshen up the root ball then place in the new pot. I Am brand new please advise thank you.

That can be fine, but not necessary. Just be sure to only soak for 15 minutes or so. It doesn't need a lot of time.
Also, make sure that your new container is only 2 or 3 inches larger on all sides. Going up too large too fast will usually lead to overwatering.
Another thing to consider...
They are very tolerant of being cramped up in their pot. In fact, they will grow better once "established" in this manner. Moving it may cause it to slow down for quite awhile as it adjusts, so the less that you do the faster it will recover. Make sure that you absolutely need to pot up before doing so, as you could end up causing more damage than it is worth in the long run.
