As I've mentioned a few times, we had a really wet spring, and a really dry hot summer leading to there being very little stored honey in the hives and necessitating taking action and feeding them. I fed through the fall with 3:2 sugar syrup and now that they're not longer taking syrup, I'm feeding with granulated sugar. Granulated sugar has some goods and some bads. The goods are that the bees can take it even when it's cold, it doesn't cause robbing, and it helps absorb moisture in the hive. The bads are that the bees don't always take it and they might just clean it out like any other refuse.
The shims that I use (which I lovingly refer to as 'Parker Shims') make a good space to pile sugar on top of a paper towel. To the left in the picture below, there is a frame feeder and it is full up with sugar as well. We'll see how this turns out.
