Pruning may save valuable ash trees from death in ash dieback

Pruning infected ash trees may temporarily save them from death caused by ash dieback, but so far there has been a lack of knowledge as to how much to remove of infected branches. A new study from

Decline in tree growth for years following Gremmeniella-infection
