PVA glue should do the trick as long as the mating surfaces meet up.

What I would do (but I am sure there are many other methods).

Drill a small hole in the bottom of the tree trunk and a corresponding hole in your diorama where the stump is to go. Cut a short piece of brass rod, and use CA to secure it in the stump, once dry (seconds to minutes depending on what CA you are using) use CA again to secure the brass rod into the diorama, and viola....stump attached.

Whatever glue you use, I would second the recommendation to use rods to help strengthen the stumps so that they don't get knocked off. It will help with the bond as well.

Would'nt the plaster absorb the CA Though?

I thought of the PVA to but I thought it would be too weak a bond. How about epoxy resin?

Actually it shouldn't be a problem. I've experimented with PVA and CA and haven't had a problem with the plaster soaking it up. I found that I prefer wood glue for something like this.

*edit: Use the CA gel if you want to go that route.

I agree with Jeremy on this ..i use PVA alot and it may take a while to dry but once dry its a super strong grip ,,the rod is a very good idea but one real good thing about PVA ..well 2 things really ,,its easy to clean up any cock ups and with stumps it also fills any gaps left around the base ,,makes it quite easy to blend into the ground ,,at last count is have 18 bottles of PVA ,,different strenghts and marine grades ..love the stuff .

+1 on the PVA. I use it all the time for plaster. It does take a long time to dry but once dry the bond is very strong
