Tree Planting: To Stake or Not to Stake?

An example of improper staking.
Staking is often the last step of the tree planting process, but is it really beneficial? Typically, rigid stakes are driven into the ground near the trunk on two sides and plastic or vinyl ties are wrapped around the tree trunk and attached to the stakes. We do this to provide structural support for the newly planted tree, but most trees do not need to be staked. Trees that are staked focus more energy into height and crown growth resulting in slender trunks that are less wind firm, while trees that are not staked focus more energy on root and trunk diameter growth, developing a strong support system. The ability to flex and bend in the wind creates a stronger tree.
When properly done, staking can be helpful for bare root trees or trees planted in very windy areas, but containerized and balled and burlapped nursery stock generally don’t need it. Improper staking is too common, with ties wrapped too tightly around the trunk or left on the tree long after establishment, which can lead to girdling over time.
Proper staking involves placing stakes low to help stabilize the root ball rather than the trunk, using flexible materials to tie the tree to the stakes allowing the trunk to move, and removing ties and stakes within the first growing season.
Next time you plant a tree, consider forgoing the stakes. The last step of your planting process could be adding a mulch ring around the tree instead! Mulch helps to insulate the soil and retain moisture, but too much mulch can be harmful. Generally, a 3” deep ring of mulch in a 4’ circle around your tree is sufficient, but don’t pile mulch against the tree trunk.
