I am overwinter some peppers.
I grew them in 5 gallon sub irrigated buckets and they did well, considering the were overshadowed by the nearby tomatoes.
To prep the peppers, I cut them back hard and filled the sub
irrigation reservoirs to overflowing.
I've had problems with keeping overwintered peppers properly hydrated, dormant and safe from
mice.
This year I'm using some
bucket bells to adress these issues
They are left over from a wintersowing potatoe experiment.
Here is a photo of the plant, bell, and bell lid:
