Shadelands is Greening and Growing in More Ways Than One!
Located at the southwest corner of Shadelands Drive and N. Wiget Lane you’ll find a gem of a garden: Our Garden, a one-acre public demonstration garden built and maintained by Master Gardener volunteers, graduates of the UC Master Gardener Program of Contra Costa County.
Our Garden Master Gardeners are local residents who have trained through the University of California Cooperative Extension and now share their knowledge and enthusiasm for gardening with community members. Their focus is to educate home, community, and school gardeners in sustainable, environmentally friendly gardening practices, and to help gardeners succeed in their planting, nurturing, and harvesting efforts.
Originally established in Shadelands in 2009 on land that is now part of the Shadelands SportsMall, Our Garden moved to its current location on Shadelands Drive at N, Wiget Lane in 2012. Today, Our Garden is a go-to destination for growers of all abilities, from beginner to experienced. Our Garden showcases gardening methods and best practices for Contra Costa County gardens, and provides educational resources, expert answers to gardening questions—and encouragement—for home gardeners.
Our Garden is prolific indeed. You name it, Master Gardeners grow it. Tomatoes. Squash. Leeks. Garlic. Peas. Beans. Onions. Artichokes. Okra. Eggplant. Kale. And so much more. During their growing seasons, the orchard is lush with apples, pears, citrus, stone fruits, and even avocados. Trees are pruned short and manageable for the home gardener.
Green and red table grapes grow in the vineyard. Ornamentals bloom. Winter crops of lettuce, broccoli, and cabbage keep Our Garden producing year round.
“Our Garden is an outdoor classroom and a free resource for all community members and gardeners,“ said Janet Miller, the garden manager and a Master Gardener since 2008. “We’re open to the public Wednesdays, 9am to noon, April through October, and we invite people to come visit—we love to show others what we’re doing and hear what our home gardeners have to say about their gardens.”
Visitors are encouraged to wander through the garden and watch the Master Gardeners tending to the plants, beds, trees, and vines. They’re encouraged to attend weekly talks, which are held Wednesdays, 10–11:30am, under the big oak tree. And they’re invited to step up to the Ask a Master Gardener table—staffed Wednesdays, 9am–noon—and ask a Master Gardener for advice and answers to their most vexing gardening questions.
Master Gardeners provide University of California research-based horticultural information through their volunteer efforts as UC Master Gardeners. It is the acquisition of knowledge, the skill in gardening, and their passion to give back to the community that distinguishes a UC Master Gardener. Because of this, they have become trusted resources for all things garden-related.
The UC Master Gardeners Help Desk is another resource for the community, available year round by phone (925.608.6683) and email ([email protected]) for gardening questions and information. Staffed M-Th, 9am to noon, Help Desk volunteers can help identify a mysterious pest, locate the best plants for a specific situation, and offer advice for sustainable gardening practices in specific soils and climates.
The demonstration garden’s bounty serves another purpose. Throughout the growing season, Master Gardeners harvest produce twice a week and deliver fresh picked, organic fruits and vegetable to the Monument Crisis Center year round, which averages between six and seven tons of healthy, seasonal food for our hungry neighbors.
Kicking off the summer growing season, Our Garden holds the annual Great Tomato Plant Sale in April over the course of four days.
Mary Jo Corby, a Master Gardener since 2013, is the plant sales coordinator for the Great Tomato Plant Sale. “The Great Tomato Plant Sale is our major fundraiser for UC Master Gardeners of Contra Costa County, supporting all our other programs and projects, of which there are many.”
This year’s sale was a huge success, selling out most of the inventory of more than 27,450 plants: 13,400+ tomatoes, 5,500+ peppers, and 8,500+ other vegetables and herbs.
“We held our first Great Tomato Plant Sale at our original location in 2011,” said Janet. “We scheduled the sale to last three days, and we sold out in three hours! We learned to grow more plants after that.”
The Our Garden website is a wealth of information about the annual sale, the available inventory, and how to plant and tend to young veggies and herbs once you get them home. For those who missed this year’s sale, mark your calendar for April 2026 and visit Our Garden for updates.
“We’re all volunteers,” said Mary Jo. “And as volunteers, for the amount of time and work we commit, you have to have a passion about gardening. And that’s one thing we have in abundance: passion for this work in the garden and for sharing the joy of gardening with others. We’re an energized group because this is what we love.”
In addition to their work at the Our Garden site, Master Gardeners also present educational materials and talks on sustainable gardening at libraries, schools, and other public venues throughout Contra Costa County. You’ll find Our Garden Master Gardeners on Saturdays at the Diablo Valley Farmers’ Market, just up the street, N. Wiget Lane at Mitchell Drive.
Our Garden is one of three gardens in the UC Master Gardener Program of Contra Costa County, each with its own focus. Our Garden in Walnut Creek focuses on helping home gardeners with sustainable, organic home gardens. Rivertown in Antioch focuses on different methods of planting, such as vertical planting. The Low Water Demonstration Garden in Richmond focuses on low water and drought tolerant plants.
