Summary A pruning trial in Eucalyptus grandis with six pruning regimes and a control displayed negligible effects on growth rates. Recovery after removal of up to 50% of the live crown was rapid. Gains in knot-free timber were insignificantly small while degrade due to stresses induced by severe pruning were not significant. Corrective pruning and brashing for access only is advocated.
