The question that really needs asking, given so many hobbyists think it is feasible to is produce, overwinter and sell queens in the UK in early spring for a profit......Is why are no major commercial operations set up in the UK to do this?
ITTLD once explained that the costs associated with doing it made it unprofitable.
So it's a basic non starter. when you can buy good quality Italian/ Carniolan etc queens from around April time from the continent.
It seems that many hobbyists want new bees in the Spring,
feed copiously,
perhaps over inspect,
panic that their charges will swarm,
get either elated with a crop of honey,
or dispondant because the bees have eaten the crop...
overdo the varroa control,or do none at all
open the colony in the depth of winter and pour acid and syrup over the clustered bees.....
panic over feeding fondant...
Find a box of dead bees on St David's Day
Order a new box of bees for the Spring
Do this for two seasons and give up!
Perhaps there need to be a change in practice, and teach new beekeepers how to manage their bees...
and ( Tin Hats Ready) buy bees that are adapted to our climate, bred in the UK.... not ones IMPORTED from the Mediterranean? ( or force bred on German /Dutch/Danish islands?)
There are a few breeders in the UK who actually breed bees and raise queens for sale, bees bred in the UK from their own stock... not imported breeder queens... some even sell overwintered stock.
All at a price of course... you get what you pay for!
Unfortunately there are many who IMPORT and sell on, I was offered LOCAL PLYMOUTH Italian or Italian Buckfast Queens from Gozo ( Malta) for £27 each to requeen my colonies ( why requeen all my queens seem to be good to go!)
Then perhaps the market for early bees and queens would diminish??
I do not think that the argument that "the local bees are rubbish/angry etc etc" so I import cheap bees from wompopo land stands up.
A capable beekeeper, as with DREX et al are doing something about improving his stock, without the environmental expense and need to import
