Linda, thanks for contacting us about staking new trees.

Research indicates staking is not needed except in high wind or high traffic situations, and then for just a year. The roots need to “flex” in order to strengthen and expand. Keeping the supports on does not let them develop “muscle” – to use a human term! If you do use stakes, be sure to remove any straps, ties, bamboo posts, tags, etc. – all of which can “girdle” the tree cutting off its vascular system. Proper planting will stabilize the tree and give it a great start. See these fact sheets for diagrams and more details.
