We graft 3 times/week from the end of March until mid-September, which represents approximately 60 mornings/year.
Each season, we produce more than 15 000 royal cells.

In order to maintain a large genetic diversity, each year, we graft on 60 lineages coming from inbreeding.

At each grafting, we take off frames in 10 strains colonies. Those frames containing different origins of queens are offered to the bee-keepers 5 weeks later.

The grafting always takes place in the morning time and we use Chinese Grafting tools. Each grafting takes one hour for a total of forty bars.
