You didn't say which variety but I suspect you're fine. I have had some peppers that really didn't care for the sub-50 temps and I've had some that seem to do fine. It's best to transplant seedlings to their summer homes after the last freeze date for your area though. But, since you've taken precautions with covering (which is smart), I think your plants will take off shortly. Good luck!

No, ive had year old peppers in a tiny styrofoam cup that were 5" tall at a year old. When i potted them up the 2nd year in a bigger container with better soil they grew to normal sized pepper plants.

Thanks for the responses, I am glad to hear this!

I have a lot of varieties, most very common but ranging in widely in origin. I did wait until the last
average frost date, so it has not gotten THAT cold. Although it did frost once, but not in my little
urban garden. Most years around here, plants are in the ground by now, but these cold nights are being very persistent!

Reyna, good to know! Would you recommend fertilizing at this small stage?
Or waiting until the weather warms a bit so they are growing faster/absorbing more nutrients?

I am SO glad to hear it's not permanent stunting. I started my peppers in early Feb and they still seem so small....

Phill my man! Glad to see you out and about. It has been a while and I was worried you had dropped off the planet.:) Good to have you back.

When I have plants that are stunted I move them to a new container. It is usually over watered( soil is too compact and won't dry out) or too much NPK. I had a bhut that stayed 4 inches tall for 4 months. Moved it twice till it found a happy home. Now it is 5 feet tall.
