Title: Over Wintering Top Bar Hives in Canada
Post by: td182b on September 28, 2013, 05:59:14 pm
Anyone from Canada having success over-wintering top-bar hives in Canada? Will they be able to move horizontally? I am in the north end of the Okanogan, lowest winter temperatures in the -30 C, -20 F range.
I'm really interested in these, I have a few Langstroth hives, but am really interested in letting the bee's do their own thing, and I would rather not have to use the chemical treatments if I can avoid it. Too many years of farming with agricultural chemicals caused me to have to sell the farm and move off the prairie's.

I get -27 F sometimes for a few weeks and it hasn't killed my top bar hives.  Any hive, of course, can die.  I think the important thing with a top bar hive is that the bees are at one end the the stores in front (or behind if you see it that way) of them so they can eat their way to one end and not leave stores behind them.  When I have lost a horizontal hive it is usually because the cluster was in the middle and ate its way to one end leaving stores at the other end that they couldn't move to.

Thanks, makes me feel better. I really want to try the top bar hives, and your low temps are colder than anything we should experience here (unless we're going into Global Cooling again....)
I have a band saw mill, so was thinking of making the outside boards of the hive at least 2 inches thick to help with the hot/cold insulation factor. Thoughts?

Just a note of interest; I have your book, 'The Practical Beekeeper'. Extremely interesting reading.

More insulation won't hurt, of course.  Some insulation on the roof will help more than any place else.

Wow! That's cold. We don't get it that low here, probably only down to +10F at worst. Had 2 TBH's in the back yard for the past 5 years and not lost a colony to winter yet. As Michael suggests, insulation on top of the roof is I think, the best place to put it. That's all I do, nothing else inside the hives. As is often quoted, its not the cold that kills bee, its the damp and the mould.
