Hello Tom,Carol,Dave and all Bee-Liners:
My hope is that this thread will expand and flourish, as it is an
area of beekeeping in which I am particularly interested.
I only have 5 years experience over-wintering bees and its only been
in the last 2 or 3 that I felt knowledgable enough to even have an
opinion on this subject based on my observations but here goes FWIW.
I am located in the NE corner of Vermont, USA. My latitude is approx
43 deg North. Our winters seem closely aligned with Tom and Dave in
terms of length with OCt 1 being the date in which temps and
'good flying' weather diminish. This October we have had 10-12 'good'
days. From now on these days will dwindle quickly. November is notorious
for being bleak. Someone told me just the other day that the highest
number
of suicides in Vermont each year occur in November. But I digress.
Our temps throughout winter can range from the low to mid 20's F to
-30+F,
with the coldest period being the month of January (for the most part).
The duration of Sub-zero weather can be 1 - 2 days to 7 -10 at a
stretch.
(On December 2nd 1989 it went to -21F and didn't get above zero until
January 3rd, 1990!...my first winter in Vermont!!! Brrrrr....)The spring
temps don't reach above 30F until the middle of April. It seems that
our biggest problem is the mid-winter thaws that are typical for this
area. Temps can get up into the high 40's for a few days in late January
or February. Then in the space of one night they plunge back to single
digits. This really stresses the hives. Many break cluster and can't
re-cluster before the cold weather returns.
The main difference between us and Alaska of course is the length of
daylight. Now that we're back to standard time, Sunset is at 4:30PM and
will be pretty close to 4:00PM by the time December 21st gets here.
Sunrise
is about 6:00AM. I know that this 'day' is way longer than what you
folks
get in Alaska at mid-winter, and I wonder if this could be a major
factor
in over-wintering your bees. Your winter temps are balmy by our
standards,
probably because of the oceanic influence.
When I first started beekeeping, Vermont had a ban on importing
bees from outside the state. This was a futile attempt at keeping varroa
out. The ban was lifted in 1992 (don't quote me on the year). Before
then
I purchased splits from my mentor. After the ban was lifted I bought
bees from down south, not for any other reason than I thought that's
where all good little bees came from. I shopped around some and settled
on Double Hybrids from the York Bee Co. in Jesup Georgia, USA. They have
been my primary supplier ever since.
I am happy to report (knocking on an inner cover for luck) that the
only
winter kills that I have experienced have been because of my own
ineptness
or lack of understanding. I'll spare you the depressing details.
I have tried the various forms of wrapping, insulating, ventilating
etc...
and have finally settled on locating the hives with a southern exposure,
not wrapping or insulating, providing upper entrances for ventilation
and cleansing flights and placing stockade fencing as a wind break from
the prevailing northwest winds. I leave accumulated snow around the
hives,
but I do clear away snow from the south-facing fronts. I am highly
satisfied with this approach. (But Allen's recent ominous musings
re:feeding
honey, will haunt me for the rest of my days!)
Now Vermonters are an independent bunch, and I suspect most beekeepers
everywhere are equally independent. It seems to me that for as many
beekeepers that I have met, so to are there at least that many different
ways of dealing with the same problem. If I am at one extreme (not
insulating) there is another fellow up the road who has his hives
encased in 2" thick polystyrene foam insulation, with a super or
deep over
the inner cover filled with fiberglass insulation, with just as much
success at over-wintering as I have had. Go figure.
My point in this short story made long is that the origin of the bees
doesn't seem to relate to survivability in my experience. My suspicion
is that it is most closely related to the breed, but I don't have
enough knowledge on this topic to have any more than a gut feeling.
I look forward to reading more about this fascinating topic.
Sorry for the length. I'm home alone this week and have no one
else to talk to! ;-(
