An eco-friendly method to get rid of a tree trunk in dry weather is to cover the tree trunk with pieces of charcoal, dead leaves and to start a fire. You may also make use of a power shovel but this kind of intervention is a costly solution and burdensome. There exists also another method: the chemical method. Make use of a sabre or a chainsaw to make cuts in the tree trunk and apply a mix of a chemical sold at Pépinière de Labourdonnais (tondon) and used engine oil.
