Weeds & Pest Management
A great resource on how to identify weeds in your garden is to send an email to the hotline at the UCCE Master Gardeners of Orange County. They will be able to give you advice and help you identify the weed you have in your plot.
If you already know about the weed or pest, and don’t know what to do, you can find more information at the Weed/Pests section of the UCCE Master Gardeners of Orange County.
Finally, if you don’t have weeds or pests in your garden but want to learn about preventive measures and controls, you can visit the Integrated Pest Management site by the Agriculture and Natural Resources, University of California.
