We provide University-based gardening information and educational programs to you.

A Master Gardener is a volunteer of the University of California Cooperative Extension who answers questions, diagnoses plant problems, and gives horticultural assistance to the public via telephone, plant clinics, demonstrations, talks, and the mass media on vegetable gardening, trees, pesticides, recycling, soils, lawns, disease, insects (home and garden), house plants, and related topics using University supported research. Master Gardeners help to prepare for, organize and conduct specific educational activities. The Master Gardener Program is for the home gardening enthusiasts who want to learn more or have questions about composting, vegetable gardening, tree care and management, IPM, pruning, soils, lawn care and management, fruit tree management, plant diseases, water conservation, insect management (home and garden), house plants, and other related yard & garden topics.

🌱 Master Gardeners Making a Difference! 🦋🐝
Today, UC Master Gardener volunteers gathered at the Lockeford PMC to lend a helping hand alongside the Xerces Society!
Our volunteers rolled up their sleeves to unload trucks, sort plants, and help assemble habitat kits that will soon be picked up and put to good use.

These kits will help create valuable habitat for pollinators and other beneficial insects, supporting biodiversity and healthier ecosystems. 🌼🐝🦋

A big THANK YOU to our amazing volunteers for donating their time and energy to this important effort! It's always rewarding to work alongside organizations that share our passion for plants, pollinators, and protecting the environment.
The Xerces Society

We had a great monthly master gardener meeting. Anne Schellman from the UC Master Gardeners of Stanislaus County came and talked about growing tea and the different types of teas. We had a fun tea themed lunch and our spooky October desserts. We also had our fall garden swap where lots of garden goodies found new homes. It's always a great time catching up with our amazing volunteers!

Have you seen any monarch butterflies in your garden?

Monarch butterflies are on the move! 🦋 Their fall migration takes them south across North America, with many traveling hundreds or even thousands of miles to reach wintering grounds in Mexico and California.

🌱 Master Gardener Monthly Meeting Fun! 🌱
We had another great evening with our Master Gardener volunteers!
A big thank you to our guest speaker, JD Wikerts, who gave us a fun and fascinating presentation on “How Plants Get Around.” 🌿🌎 JD also brought along a great selection of succulents for sale, so a few new plants got to “get around” and head home with our volunteers! 🪴😉
We also had a productive business meeting, and—as always—our amazing volunteers knocked it out of the park with the decorations and delicious desserts! ❤️🤍💙
