I do it because it is a pain to move them. They can survive a light frost, so i let them. If you want to bring them in at 34 it would be fine, just not necessary. Your capes will die back to their roots, but come back from them in the spring. They are pretty remarkable plants when you think about it.
For the same reasons collapse said in the post above..

32 degrees is technically freezing..but..for VFT's and Sarrs in the winter, they very often get a light freeze in their native habitats..
32 is fine for them..no real danger at all..
29 is below freezing, and at 29 you can get a light frost..actual frost on the leaves of the plants..
but it would be a very *light* frost, and it would only last a few hours..as soon as the sun comes up, it will quickly rise above freezing, (in October)
a 29 degree low, in the Autumn, here in the "north" is a very "mild" cold night..its the equivalent of an unusually "cold" cold night in the south..
and I figure a light frost actually helps the plants go "fully dormant" so that they are very clearly and deeply "asleep" when
I cut off all their leaves and put them in the basement stairwell for their full winter dormancy..
So I choose "below 29" degrees as my "limit" because I know they can handle 29 just fine..
in fact, one or two 29 degree nights is probably good for them..
There is no real reason to bring them in the garage for "only" 32 degrees..
Because I know they can handle 29 degrees *for a few hours* in an early Autumn morning..
Its the 3 months straight below freezing (around here) that they cant handle..
It is worth mentioning that what happens above the soil line is one thing, but what happens below can be much more crucial when it comes to winterizing your container-grown temperate CPs. For many North American plants, a freeze down into the low twenties is inconsequential because the soil doesn't freeze more than a fraction of an inch down. Plants grown in pots, however, can freeze solid all the way through at the same temperature, which is far more damaging to the plants. If you dig a pit to overwinter your potted plants, to insulate the soil, it will be a far easier on the plants and you will have less to worry about.
All my plants, except the nep, are still outside, with lows dippibg into the low 30s. My question now is, do my sundews need to go dormant now? Do they even go dormant? Or if I bring them inside, will they try to grow all winter?
If I found a friend who'd want to plantsit for a winter, would there be no use, because my sundews would already be fixin' to be dormant (boring to a plantsitter)?
