Do you know what plants in your home and garden are toxic to your pets? There are many common plants and flowers that can cause various reactions to certain animals (and people) ranging from mild stomach disorders to even death.
Join UCCE Master Gardener Kelley Gelderman, retired DVM, as she speaks on this subject. Kelley retired in 2017 after 33 years of small animal practice and now is an active Master Gardener in San Joaquin County. Combining her knowledge of animal medicine and horticulture, this will be a presentation you do not want to miss.

What can be done to improve the chances that a home will survive wildfire? The good news is that research has demonstrated that by careful attention to the selection, location and maintenance of vegetation and other combustibles on the property (i.e., the defensible space on the property), implementing retrofits to “harden” the home, and implementing an ongoing maintenance program, it is possible to substantially improve the odds that a home will survive a future wildfire. These actions do not have to be costly, but they do require an understanding of the three types of exposures a home will experience when threatened by a wildfire.
