Re: Possible winter loss TBH - how to preserve the comb
Last year (late 2012) I left everything in there (including some capped and uncapped honey). All I did was tidy up the bottom board, scrape off the couple SHBs that were entombed in propolis and remove any combs that I didn't like (crooked mostly). Put corks in all the entrance holes and left it over the winter. I meant to do more before installing another package, but got behind and ended up installing them without cutting out moldy comb. I went back into the hive a week later, and they had everything all tidy and clean and were bringing in pollen like crazy.
I have one TBH and have yet to overwinter it. Don't do anything soley on my advice!
