I have a mandevilla/Dipladenia. Brought it in for the winter and put it in a paper bag, as I have been doing with my geraniums for years. Just pulled them out this afternoon. Geraniums are showing some growth but the Dipladenia shows nothing. I want to put it in a flower pot and fertilize as with the others. Do you think I will have any luck? Or have you heard of anyone doing that with this plant? Thanks for your time :) Julie

My best guess and from a bit of research your Dipladenia would no longer be a viable plant.
No harm in putting it in a pot and doing the 'wait and see' approach. That's the fun of gardening, sometimes you get a surprise!
Here is a link about the care of Depladenia.
