Les replantations de jardins colonisés par l'armillaire : cas du jardin botanique de Tours

Abstract : The Botanical Garden of Tours would like to renew its tree collection, while avoiding the decline of the new trees because of the honey fungus. In this report, a pedological study has been done thanks to soundings with a pedological auger, tests in laboratory on soil samples and pits dig with an excavator. Soil cartography has been made. The Garden soil is mostly homogeneous, with only one limiting factor: the alkaline pH. The autoecology of the varieties of the Garden has been studied and the development environment of the trees is generally adapted to their autoecological needs. Secondly, a list of the potential decline factors of trees has been drawn up. These factors have been then compared for trees in bad shape or trees with honey fungus and trees in good shape. The principal decline factor in the Botanical Garden seems to be the wounds and/or the biotic attackers, whereas the principal cause of the decline of a tree because of the honey fungus is its reputation as sensitive to the honey fungus. The main recommendations for the new plantings are the choice of varieties that are known as not sensitive to the honey fungus and young trees with a little constituted root development. The use of ground-cover plants and RCW (Ramial Chipped Wood) is also recommended to limit the honey fungus development, to avoid wounds on the trunk due to the lawn mower, a too frequent watering and stamping by the public.
