A Lot at Stake: Stewarding Urban Trees on the California Coast
UC Master Gardeners
Coastside Magazine article
The purpose of staking trees is to provide stability so that the tree can stay upright until the tree's root system has developed sufficiently and stakes are no longer needed. Commercially grown trees (especially smaller ones) almost always come firmly attached to a “nursery” stake. This is done to promote vertical growth and to conserve space during propagation. Trees grown in these conditions usually have weak trunks and underdeveloped root systems and often have a hard time standing on their own. Unfortunately, the nursery stake is often left securely in place. This opens the way to a host of troubles. Read more.
