James,
It depends. Wine becomes more stable the higher the alcohol, did this
just stop fermenting on it's own or do you think you added a lot of
sugar and it's just too sweet?

Non grape wines are often made sweet, if you don't like it and the
alcohol is around 10% you can do a few things such as add some acid or
wine.

If you describe what you started with and the quantities of of each
ingredient you used it may be easier to answer your question.

I have never made plum so really be be commenting in general terms at
best.

If it just stopped fermenting and the area you are making it in is cold
you may want to move it to a warmer place; it may start fermenting
again.
