Newly planted trees have yet to expand their roots into the surrounding soil. This makes them especially susceptible to blowing over in high winds and storms. To prevent a tree from blowing over after it is newly planted, it needs to be staked in several spots. When high winds blow, the tree is then restrained by the cables that are attached to it from the stake. Once the roots take hold, the stakes can be removed.
Pound three stakes into the ground around the birch tree. Pound them 18 inches into the ground and angle them outward from the tree at a slight angle. They should be 12 to 18 inches from the trunk.
Wrap a 3-inch wide strip of polyethylene strapping around the trunk of the tree. Twist the strap once so that it crosses between the stake and the tree. Staple each end of the strap to the wooden stake.
Repeat the above step for the remaining stakes.
Remove the tree stakes and the strapping from the birch tree the following growing season. Trees staked too long can become stunted in growth.
