What's the best method of getting an ivy yield of honey and how do you go about extracting it ...
The bees will find Ivy if it's around at the end of the season but bear in mind by the time the Ivy is in flower your colonies will already be reducing in numbers (my ivy flowering can be as late as October). So ..there's not always the volume of bees in the colony to be sufficient to fill supers if you have already taken your summer crop of edible honey. They will rarely draw comb out for late stores so you will need drawn supers.
I let my bees keep the ivy honey and they overwinter on this - I like my bees to have honey stores going into winter as I believe that they are healthier and less prone to things like Nosema as a result. I run 14x12 hives and the brood box can be well over three quarters full of honey going in to winter of which a large percentage is ivy.
So - if you want an ivy crop that you want to take off then you are going to have to sacrifice something:
a) Your bees if they don't have sufficient stores going in to winter.
b) Your summer crop of honey - but you will want this stored in the brood box so that they will store the ivy honey in the supers.
d) You will be sacrificing your drawn comb as you will never get the ivy honey out before it sets ... it sets in next to no time so by the time the outer comb is filled the inner has already set under the cappings.
e) It's going to be cold and wet where you are when you have supers on the hives - not ideal when they are wanting to hunker down for winter.
f) Food for winter - you are playing with fire as they will need feeding if you get it wrong.
Personally, I can't see any rational reason for wanting a crop of Ivy honey, it's foul tasting, is almost impossible to extract and is going to be difficult to get it in a super. If you have a number of colonies then you could dedicate one or two to production of Ivy honey - perhaps by bolstering the number of bees by depleting other colonies, you will need to have the brood frames largely replaced by frames filled with stores in order to get the ivy stored in the supers and then be prepared to remanipulate the stores around your hives and balance the bees - and then feed them very late in the season to ensure they have food for winter.
What a faff !! Not worth the effort in my opinion and for a beginner with apparently no hives yet - not a prayer. If you do have bees best concentrate on getting them through winter rather than trying something as esoteric as this idea. You've got every chance of ending up with no bees trying to rob an ivy crop from them ...
Aternatively, if you are an ivy honey connoiseur and you just want a jar or two .. make sure there are a couple of empty drawn brood frames in the brood box when the ivy flows - take those out as soon as the bees have filled them and warm, crush and strain. Replace the frames you have taken out with ther drawn frames and feed them immediately with 2:1 syrup. Someone will be along shortly to tell us that sugar is cheaper than honey and real beekeepers take everything they can get out of the bees .. not my choice I'm afraid.
