I wasn’t expecting that

SC a question for you please, what do you do with your old chilli plants ?, I stripped the final fruit off mine about 11/2 weeks ago, I then pulled up the plants and broke them down and put in the compost bin. I was surprised how woody the branches were when I broke them down. The root balls on some of 5nem were still quiet strong so I was wondering if perhaps I should have wrapped them up in fleece and left them in the raised bed, would they grow back next year ?

I cut the plant down to just above ground level then they go through the shredder and into the compost bin. I knock as much compost off the root balls as I can, then they go in the compost as well. 
Very unlikely they would survive just wrapping in fleece. In the tunnel. Only going to happen if you have a very mild winter. I very half heartedly try over wintering in the tunnel sometimes, I’ve only been successful once. They really need to be in the house with a constant temp of 10 degrees minimum.
