The two most common reasons for not having a success with Ross Rounds supers are: 1. Putting a super on top of two deeps. Yes, two deeps does help (a great deal) in controlling swarming, but if faced with an alternative bees will always put honey in drawn comb before drawing new comb. Practically, this means that before starting to draw the comb in the Ross Rounds super, the bees will first fill the top deep with 80 pounds of honey! By then, the flow may be over. Shake all the bees into one deep and put the Ross Round super on top. (I put three on top!) 2. The second most common mistake is to not use the strongest hive a beekeeper has. Look at www.rossrounds.com, as well as in the Bee-L archives. Producing comb honey, and specifically Ross Rounds, should be one of the greatest thrills a beekeeper can have.
