I guess it depends on your Location (how long your Winter is?) What becomes available re early Resources from your Environment too (?)
I have Several Hive types. And each one has its own needs or individual recommendations to Feeding.
Eg Warre Hives are 'under Supered' and the Honey Harvest is ideally taken after the Winter has passed.
(Bees move up into the upper Boxes gradually throughout the Winter.) And once Brood increases, they move the Nest Down into the Newer (lower) Added Comb Frames !
My jumbo Deep Langstroth Frame Horizontal Hive does things differently ! They move gradually up the Frames and Retract into a more tighter Cluster in, the Brood Area, (nearer) the Entrance. Here we add lots of Dry Sugar about x2 Inches Deep over a fine Plastic Mesh, with a tiny cut Flap (open up for Rapid Round Feeder use) : latter in the Spring ! Found fine Mesh works better than Newsprint ! And aids Hive Inspections via a 'quick peek' to see the "Bees" without them flying up all over the place and getting 'cold,'
My Poly Hives (Nats & Langs) have Raised Ecks added. Again Mesh with a Flap, applied over the Frames. With initially a Deep Layer of White Sugar. Then Fondant or / Hive Alive (Nutri-Feed) Fondant once Brood levels ramp up ! And a Smaller Rapid Round Feeder use too, if needed.
Any White Sugar that 'hardens' up into almost solid White Sugar (block) or Slabs, can be lifted up, collected in a Bucket. Hot Water add, only warm enough to turn Sugar into 1:1 Syrup and feed back to the Colonies, once Frosts are no longer experienced. Here this can nearly be up to the end of March / early April ! Remember I am in a Hilly, more Northern location than most. . . :Who Post on this Forum !
So factor in: Your Location, Regional Weather Patterns and the length or type of these. Vary to :
Urban / Rural /Costal / Inland. And which part of the UK / EU / US / World your in (!)
And how 'Strong' each Colony you have is. A Poly Nuc might need less, as its smaller and well Insulated ! Over a large old Wooden Brood Box !!! In a Cold Damp location. . .
If anything, add more Feed than needed. If it's White Sugar, it will harden down, be easily removed later. Fondant can get 'gloopy' if added to early, say mid/late Winter. I personally, in my Location (Scottish Borders) would personally add any Fondant Product, from about mid March onwards. Not before. Glee'd this from experience ! But each Beek will have to make their "Own" descision on this.
Finally : I took hardly any Honey of my Hives last Season. 2023 was not a good Spring/Summer re Honey Reserves. So unusually,
I decided to leave my Nats & Lang Hives, to manage them ike the Warres. Aka, take any spare Honey from these Hives this Spring : before Frame Cell availability is needed for Colony ramping up its Brood needs.
So far the Bees seem fine. But Winter has got a long way to go yet.
I also did my Oxalic Acid Vaping Application earlier than normal.
Done over x3 Weeks latter part of November / early December.
[Previously done near Christmas and New Year?] . . .But the Bee Community 'say' doing it at an earlier time aides the Colonies for sure. . . I guess 'Time' will tell.
But all I can say, my Bees are in a better condition, now, than this time last Year (?)
Still a fairly New (returning) Beekeeper. . .
Had Bees over x30yrs ago. But have them back in my life again.
But conditions / disease / pests are more prevalent now, than, than, in the late '80's or early 90's !!!
Over to others. . .
How are you and your Bees doing this January 2024 !?!
