Quaking aspens, with their green, fluttering leaves that turn a golden yellow in the fall, make a great addition to any home landscape. The tall, slender tree can grow up to 40 feet tall and can be grown in most well-drained soils. For the quaking aspen to develop a strong trunk and root system, only stake the trees if they will be planted in an area with strong winds, or will be in a location where they might get knocked over by children or pets.
Drive a stake about 18 to 24 inches into the ground, using a hammer or mallet. If the tree will be in a high-traffic area, make sure the top of the stake is at least 3 feet above the ground. This will make the stake and webbing more visible so passers-by can avoid them.
Connect the tree to the stake, using 3-inch webbing, polyethylene strips, nylon stockings or other non-restrictive material. Wrap the strap loosely around the midpoint of the tree and staple the ends to the stake. If the strap or webbing is too tight, it will constrict the tree's movement, which weakens the trunk and root system.
Remove the stake and webbing as soon as possible. A year is enough time for a small tree to be staked. Larger trees might need up to two years of staking.
