What to do with tomatoes

My tomato plants are grown in pots and have done well all year.

They have started to slow down and wondering what shall I do with them over winter. I have an unheated greenhouse.

What should I do

 

Toms are grown as annuals, you just throw them away at the end of the season.

 

Cheers Pete, wasnt sure. Can they be composted do you know

 

Yeah pick any green fruit to ripen indoors and then put the plants on the compost heap, just cut the woody stems up a bit.
