I didn't see the OP but I bring in green tomatoes along with the ripe
ones
and leave them in a basket in the kitchen - no special treatment.

Mine seem to go mouldy after a couple of weeks. Do you do anything
special
to them to make them keep so long?

Nothing. I do it with greenhouse and outdoor tomatoes.

But they are still on the stems so not all touching and I remove any
damaged
ones immediately - and use them :-)

One wonders how, if the tomatoes are in a basket in the kitchen with the
ripe ones, the poster manages to keep them seperate and not at all touching.
Must be a very large basket
