Seven honey locust trees that did not survive being transplanted at Millennium Park will be removed and replaced during the week of October 5.
“The trees are under warranty protection and will be replaced at no cost to the City of Chicago,” said Montel Gayles Public Buildings Commission Executive Director.
ValleyCrest, the landscape contractor, will plant seven new honey locust trees on October 7. Trees can be planted in autumn, as they will grow according to the regular seasonal cycle once transplanted.
Two trees are being replaced adjacent to the Promenade just west and north of the Pritzker Pavilion. The other five trees being replaced are immediately east of the Pritzker Pavilion.
Millennium Park contains an abundance of landscaping, including 650 trees.
As reported by the Universities of Ulster and Washington tree loss after transplanting is a serious problem. Both institutions have found failure rates for tree planting are typically 25 to 50%.
The Public Building Commission of Chicago routinely manages the design and construction of buildings and other facilities for the City of Chicago and its sister agencies. Mayor Richard M. Daley serves as chairman of the PBC.
