Am considering shifting from "wet" to "dry" sugar this year. Its starting to get cold here, I did see the Bees out weekend before last though. When do you think its a good time to start? I have 2 hives one a double super with a single on it that I left and did not harvest (pritty good size hive) and 1 that I am still trying to get started thats a single super with a single on it that is mostly empty still.
