To reduce the spread of COVID-19 pandemic and in compliance with county orders, we have adjusted our services accordingly:
- All in-person events, including library talks, are suspended
- We are not currently accepting walk-ins or specimen drop offs at our Master Gardener Information Desk at the UCCE Sonoma office. Please send an email with your inquiry to firstname.lastname@example.org. Our Information Desk team is checking the emails regularly and will respond to your questions as soon as possible.
Master Gardeners staff an Information Desk where home gardeners get personal answers to their garden questions. Our volunteer staff promotes successful gardening experiences and sustainable gardening practices by providing home gardeners with research based information from the University of California and other academic or government institutions. The volunteers have access to an extensive library, University of California Agricultural Advisors, university internet sites and a stereoscope for researching home gardening problems.
The Information Desk is located in the University of California Cooperative Extension office in Santa Rosa at 133 Aviation Blvd, Suite 109.
To provide you with a diagnosis and advice on what to do about a problem, the volunteers need as much information about the problem as they can get.
If possible, provide samples of the plant that show the problem plus samples that do not show the problem.
Plant specimens should be fresh and submitted in sealed plastic bags. Include leaves, stems, roots, flowers and fruits when possible.
Insects that are submitted for identification should be in alive and in plastic bags or plastic jars with secure lids.
If you phone or email your questions and can get to the office but not when it is open, you can leave your sample, labeled with your name and contact information, in the drop-box in front of the office. Please fill out the goldenrod-colored specimen card with your name, phone number, email address plus information about the problem. Be sure to fill out both sides of the card.
If you are unable to provide samples of plants or insects, provide clear photos if you can.
Please be ready to answer these questions. If emailing your diagnosis request, include this information in your email. In any case, provide as much information as you can.
