How to Stake Your Tree
Staking newly planted trees is warranted in very open sites that are exposed to strong winds, such as new housing developments. Tall trees with small root balls also may need to be staked. Without support in these situations, trees amy become tilted and movement of the root ball in the planting hole may damage the tree’s fine, absorbing roots. If a tree is supported the ties should be removed as soon as possible, hopefully after one growing season.
Perhaps the greatest advantage of supporting trees against the wind is that the staking materials provide barriers to physical damage of tree trunks by lawnmowers and other landscaping equipment. Leaving the stakes as trunk guards after the supporting ties are removed from a tree may be useful as long as they don’t pose a hazard.
