In the autumn of 2019, in collaboration with the local action group Nov’Ardenne, lanceolate plantain was planted as ground cover in a plot intended for Nordmann planting in the spring of 2020. The aim of this sowing is to limit weeds as much as possible and thus avoid the use of phytosanitary products. After several weeks, we were able to see that the plantain had become well established and developed, which bodes well for the continuation of the trial. During the month of March, the young fir seedlings were planted. If the trial is successful, these trees will not see the shadow of a pesticide during their life cycle.
