Tomato plants

Hi all this may seem a strange question but i was wondering about keeping tomato plants for a second year. The reason behind this is i manage a garden project and we havd a large polytunnel with several tomato plants in it. Some of the plant stems are  sending out what appear to be roots. I wondered if layering one would result in new plants growing from the old stem? Can anyone advise or enlighten me?

many thanks

Honestly-no -it is not worth the effort- and no you will not get a new plant from layering.

The best place is the compost heap -start afresh next year.

Cheers compost heap it will be! 

Thanks. they will make a good contribution to compost heap.
