The exhibition space has been filled by 260 companies, including 72 suppliers, and there is currently a waiting list. Most participants come from the Netherlands, with some from Belgium, Italy, Poland, Germany, France and England.
GrootGroenPlus treasurer Jan de Vries said: "We have noticed that participants request more square footage in order to be able to present their products properly. We do not want to squeeze in any more participants. However, we are trying to find extra space for those on the waiting list."
The trade show, which takes place on 3-5 October, will feature a range of products, mostly geared to the amenity market.
Also taking place next week, on 3-4 October in Dodewaard near Opheusden, also in the Netherlands, is a new trade fair for the avenue tree sector, Expo TCO.
The show, held in partnership with GrootGroenPlus, has been organised by the Tree & Plant Trade Fair Association for Opheusden & Surrounding Areas to promote the region, which has 130 nurseries producing avenue and ornamental trees.
There will be 75 nurseries from the area as well as companies from outside the region. The show will also feature demonstrations of machines and equipment from eight different firms.
