Hello
@ocsdfw, your desert rose is lovely
If it were mine, sure I will reuse the container, so as you plan, unpot, trim roots, add/improve the soil, repot, raise it a bit as you repot, do not water right away give it about a week, then water. I do not dip my plant in anything when I repot..no issues..no need to do anything otherwise.
I do that too, keeping my Adenium in its current container since I love the container it currently has.
I am just waiting for time too, soon my plant will enjoy outdoors..just got to wait for the overnight temps to stabilize better.
