Hi Pete. Been nice here for a few days too: hopefully help to mature the chillies.

I don't think anywhere in UK has the climate to grow/mature/ripen chillies outside. But you've got some good ones there

These were in pots outside, I just moved them into the greenhouse today. Getting a little cold in the mornings. and the really hot weather is now gone. No idea what I've done right but this is my best Chilli year ever

I would go for the unheated room, thats warm enough for them/it, bring them in late october, dont let them suffer frost though, remove all fruit and cut the plant back, look up overwintering chilli plants on youtube, if its a bright room i would probably shade it somehow, you dont want it waking up and sprouting,

Do not feed it until it shows signs of new growth in the spring, just keep the soil from drying out, too much water will rot the roots, good luck

All my previous plants have died at the end of the year. Are you saying you can keep them year after year?

Not sure what to do with mine, how long can you keep the sauce?
