Re: Sugar syrup in the winter?
Amen Bdeaner's comments. And, just because temps are above freezing doesn't mean that the bees can break cluster to get to syrup how ever you make it available to them.
If you feel like your hive(s) need supplimental feeding then use the Dry Sugar Feeding Method. Lay a sheet or two of newspaper across the top bars of your hive and pour a 5 lb bag of sugar into it, fold the sides up and place covers back on w/ something to weigh them down so they don't blow off. If you have a shallow feeder rim all the better. A rim of 1 1/2 inch to 2 inches tall is best.
Just because something is new to you, doesn't mean it is new, or revolutionary. Mark Berninghausen
