Sorry to confuse the issue but we have grown "Roma Improved" which is
determinate ie. a bush variety and have also grown "Vicki" which is a mini
plum but indeterminate ie. you grow it as a cordon.
The Roma could not be made to grow as a cordon at all, and I tried, so I
would expect it to be obvious in due course what the plants want to be.

Bob, could you clarify the difference between determinate and
indeterminate tomatoes please? It is something I have frequently seen
referred to in this group, but have never been quite sure what it is.
TIA
