A sciame: scopi e condizioni di successo.

Swarming is performed for many purposes: -- to double the colonies -- to contain varroasis -- to contain and combat brood diseases -- to renew the nest combs. There are at least three essential conditions for success: 1. Start with a very strong colony (at least 2-3 supers filled in the final stage). 2. Perform the operation in late June or early July. 3. Feed generously in July and August (there are many waxy layers to build and supplies to replenish).
