Overwintering aubergine and chilli

My 1st year having a green house. I've read about bubble wrapping to keep 'some' warmth in. I have various aubergines and chilli plants in pots I'd like to keep for next year if possible. Should I trim them down to 10cm (2inch) and leave them to hibernate? Any tips appreciated.

 

I trim my chilis back but not that far, so they have like 5 leaves left. it gives them some energy to continue still. some people do remove every leaf but cut back to the last big nodes, which could still be fairly big. If the greenhouse gets below like 3c you might need protection, I dont know as I keep mine inside in a bathroom.

 

I don't keep either over winter, greenhouse not warm enough and the house not light enough.
Also when I have tried it they are a magnet for whitefly and greenfly.
So I clear them out and start new chillis off in early Feb on a heated propagator under a grow light.

 

Mine always get pests by spring but I keep them seperate from houseplants so I dont mind, they go outside where there are predators and the problem is resolved soon enough. Spider mites might be more of an issue, ladybirds dont seem to have the taste for them.
