Around 70 plant and nature lovers founded the Otterfing Horticultural Association in 1974. More than 200 members have joined the association, many of whom are significantly involved in Otterfinger's image.

Garden trips have been taking place regularly for over 30 years. The big anniversary will be celebrated on April 13th and 14th in the auditorium in the school in the town of Otterfings, in the German state of Rhineland-Palatinate.
