Jan Willem de Groot

Title: Trees – A Lifespan Approach

Abstract of presentation: Still too often trees die prematurely or must be removed because of mechanical problems. The costly investment that has been done for these trees is thus nullified. If we want our new planted trees to be successful one day, we must plant them in the right conditions and give them the right tree management. In his presentation Jan Willem de Groot will focus on the importance of young tree management. Based on his experience in The Netherlands he will show how important and effective the pruning of young trees based on a predetermined plan is.
