WHAT YOU NEED TO KNOW ABOUT STAKING NEW TREES By Davey Trees
While it seems like young trees need extra support, most trees don’t need to be staked. Staking trees that don’t need it can cause the tree to grow fewer roots and develop a weak tree base. Only stake your tree if it needs extra support, protection, or help staying anchored.
SHOULD YOU STAKE YOUR NEW TREE?
If you properly planted a healthy tree with a sturdy trunk and solid root system, chances are you won’t have to stake it. You also don’t have to stake evergreens, conifers or trees that have branches growing lower to the ground. There are times when you should stake trees, though.

HOW LONG SHOULD YOU KEEP A TREE STAKED?
Generally, remove the stake the next growing season. If you add a stake in spring, remove in fall. If you stake in fall, remove in spring. Otherwise, the tree will depend on the stake and won’t stand on its own.
Also, make sure you always remove any constrictions around the branches like tags or ties etc! The tree can eventually grow around these, which could potentially cut off the flow of water and nutrients and kill the branch or tree.
