Staking
Most trees do not need staking. Trees that are top heavy (tree canopy acts as a sail in windy conditions) or on a windy exposed site should be staked to anchor their root-balls so roots growing from the root-ball into adjacent soil are not injured when the root-ball moves in response to wind. To stake a tree, drive two or three stakes into firm soil equidistantly around the tree. Connect the stakes to the trunk with flexible straps designed for this use (make sure straps do not injure the bark). Allow for some movement in the tree since tree sway encourages the development of a strong trunk. Remove the stakes after one growing season.
