Splitting Colonies is an important means of colony increase and swarming mitigation. Splitting is an art as much as a science. It should be noted splitting timing will vary year to year based on the local weather and conditions. This book contains information on when to split based on when the nectar flow starts in your area. Several splitting methods are discussed such as a "walk away split," split with a mated queen, and a split with swarm cells. Each method has its benefits and detriments. The genesis for this book was a Bee Culture article (Splitting Colonies: Second Edition, Bee Culture, July, 2022).
