    Tips for Tree Maintenance and Care

    The City of Pasadena is proud to have thousands of mature trees that contribute long-term aesthetic, environmental and economic benefits to the City.  Our beautiful trees offer color, shape, texture and scale to our urban environment while filtering out air and water pollutants, increasing oxygen levels and reducing solar glare.  The Department of Public Works offers the following tips for maintaining trees or visit Pasadena Water and Power http://cityofpasadena.net/waterandpower/healthytrees/.

    Polypagous Shot Hole Borer

    The Polyphagous shot hole borer (PSHB) beetle has been identified on public and private trees within the City of Pasadena. The insect attacks a variety of tree species by boring into the wood of a tree and depositing a fungus known as Fusarium, which can eventually kill the host tree.

    The Department of Public Works is working with experts from University of California Riverside Center for Invasive Species Research and The Huntington Botanical Gardens to develop best management practices in an effort to manage the PSHB. Residents are encouraged to review the following information about the Fusarium disease and the PSHB to protect your trees.
