I started my bell peppers in the house in March. Now they are just developing peppers but they are still green. I find them very 'slow-in-coming' as compared to other vegetables. I know our season is short up here in NY. As soon as the peppers really start cranking them out, the cold gets them and it's all over. Maybe I should start them in February next year.

They're definitely plants that need a long growing season in maximum sun, starting them indoors in late February or March is a good idea. It also seems to me that they do best in larger pots.
There's a common assumption that chillies are annuals but given a warm, sunny windowsill or the like they'll live through Winter in pots. Take all the necessary precautions against red spider mite though!! Then you've got a head start once there's no chance of frost in Spring.
If they're a bit too leggy for a windowsill you can trim them like pollarding a small tree

I started my chillies at the end of march and they are just forming flower buds. the bell peppers are a little further on with small peppers forming. they are in large pots in the greenhouse. I started feeding when the flowers buds started to form.

I think next year I'll start them in mid-February and more plants. Once the seedlings reach 10 inches or so, I like to top them off to increase fruit production. This sets them back but some keel over. Gonna try Poblanos & Jalapeños.

I'd go a bit earlier with pinching out for bushiness BG, maybe 6-7 inches. Pinching off the first few flowers also helps production long-term. Jalapeño can be quite varied in their heat level as they're often brined or pickled. Cayenne are more consistently hot, easy to grow & perfect for drying & grinding to powder.
I'm going to give Aji Lemon a go next year along with collecting seed from this year's crop which has been pretty successful.
This is worth a look:

Thanks for the tip Darren. Can't wait to make Jalapeño Poppers. Stuffed with sharp cheddar cheese, wrapped in bacon, then roasted for 20 minutes. yum!

Overwintering chillis in pots is worth trying too!😊
I'm completely addicted to the preserved Cherry Bomb type in jars that I buy locally. Dr. probably wouldn't approve of the salt content re: blood pressure but what would he know...

Joan, repeatedly letting them dry out until they're nearly wilting then soaking them may force flowering

Thanks all you chilli heads! I think I must be overreacting, My experience is the same as Seaburngirl I think. I did retain one plant last year with a view to growing it indoors over winter but it died. I have been told you can get more success with Numix as they produce for longer and I have a few of those. I do prefer container growing but I had far too many chillies and bell peppers germinating and ran out of decent sized pots this time.

Thanks again, Darren8!
