Organisers suggest using www.flowertrials.nl to plan routes through the Westlans, Alsmeer and Rheinland areas.
On the website visitors can also register to visit the locations of their choice.
Following registration, a badge will be printed at the first trials location that is then valid for all following locations.
Also available for visitors is a new Flower Trials App for Android and iOS, which offers practical information and news about the event.
The Flower Trials have been organised in the current form since 2004. By grouping together and holding simultaneous open days, companies aim to publicise their event and attract more international visitors.
