Older members of the hamlet are usually responsible for planting and growing the dahlias, while younger ones build the floats in large temporary tents that are built exclusively for the event.
A professional and independent jury decides which float is the most beautiful and which hamlet will be crowned the winner of that year.
[3] This ratification was publicly announced during the parade on 2 September 2012 by State Secretary Halbe Zijlstra.
A lot of time is spent as the competition is fierce and the floats are judged to high aesthetic standards.
The parade takes place on the first Sunday of September but the volunteer builders work on their floats all summer.
After a long evening working on the float people drink a beer together and most hamlets organize all kinds of other activities like song contests and barbecues.
