Staking trees is beneficial if planted in a windy location.
If you are only using one stake, place it on the side the wind usually comes from (this is generally the west or north-west side). If using two stakes, place them across from each other. Place the stake 10”- 14” away from the young tree. Use a rubber garden hose as a cushion between the tree and the wire. Do not put the stake right up against the tree because the tree will get scarred by the stake during wind movement. This will cause the tree to not properly develop tissue strength to resist the wind in the future.
