NOTICE: Seeds from China

Unsolicited seeds from China have been arriving in the United States. To ensure that those seeds do not pose a threat to US and California Agriculture, the USDA and the California Department of Food and Agriculture are collecting the seeds with their packaging. If you receive a seed packet from China: 

  • DO NOT plant it or open it!
  • Write your name, address, email and phone number on a piece of paper
  • If you accidentally opened the package, place the packaging and all seeds in a zip lock bag. 
  • Drop off your seed packet with your name, address, phone number and email address to the UC Cooperative Extension Office at 5009 Fairgrounds Rd., Mariposa CA 95338. We would be happy to send them in for you.

Please feel free to call us at 209-966-2417 with any questions. 

Growing Garlic

Fall and winter is the time to let your garlic grow to be harvested in early to mid-summer. Although the weather is getting cold here in the foothills, we often have periods of warmer weather, so if you missed your November planting of garlic, you still have an opportunity. Here are some great resources for you from the UC Master Gardeners of Mariposa County.
