More weeding material

“Weeds of California and Other Western States” is a prize-winning reference book co-written by Joseph DiTomaso and published by the University of California in 2007.

The California Invasive Plant Council website details the things that can spread accidentally or uncontrollably. The council’s website also sells DiTomaso’s book: https://www.cal-ipc.org

The University of California Integrated Pest Management weed gallery can help to identify weeds in the garden: https://www.ipm.ucdavis.edu/PMG/weeds_intro.html.
