Presentation Center Retreat Demonstration Garden

MG Field Project Presentation

In 2004, the Master Gardeners established a new demonstration garden at Presentation Center, an international retreat and educational gathering place. Nestled in the woody foothills of Los Gatos, this organic sustainable garden provides produce for the Center's dining hall. It was established directly on the site of an abandoned tennis court by layering gravel and soil.

Berger Water-wise Demonstration Garden

(San Jose)
MG Field Project Berger WWDG
The Berger Water-wise Demo garden was created in Fall 2013, based on a design by Master Gardener Rebecca Schoenenberger. The garden provides a good example of what area homeowners and business might consider when replacing a lawn with drought-tolerant plants. While the garden consists primarily of California natives, there are a number of other drought-tolerant plants from areas around the world that share our Mediterranean climate. Now that the garden installation phase has been completed, we will soon begin offering seasonal, hands-on workshops on native plant pruning, long-term native garden care, drip irrigation, and sheet mulching. A downloadable .pdf plant list is available here.

Berger Edibles Demonstration Garden

(San Jose)
MG Field Project Berger EDG
Berger Edible Demonstration Garden is open to the public on Tuesdays from 10:30am to 12:30pm.  People are welcome to visit the garden and feel free to ask questions while they are in the garden.  Our Master Gardener team is very friendly and we welcome the opportunity to answer questions about the plants and vegetables growing in the garden.  The plantings will change seasonally, offering a visual example of what can be grown in our Bay Area climate year round.

The Berger Edible garden will offer Open Garden Days during which the public and the county employees will have the opportunity to come into the garden and work with our team of Master Gardeners, hands on with tasks such as seeding, transplanting and soil management, composting, vermicomposting and more.  We plan to offer “Mini” presentations that will be available to both County employees and the public at large during the workweek lunch hours.  Our goal is to teach practical attainable gardening skills to both improve the life styles, healthy eating, and also benefit the environment through education and smart gardening practices

Master Gardeners conduct trials of ornamentals and vegetable plants to support plant selection for our program and provide information to the public regarding varietals selection in our county. Provide an educational site open to the public that leverages the unique trial focus of the raised beds and Growing Grounds infrastructure. Promote research and science literacy by teaching how the scientific method is used in determining which vegetable and ornamental varieties are selected, and how they are tested.  Through classes with Garden to Table, provide education and outreach by presenting Master Gardener education programs to the local and wider community as an example of where and how food can be grown in an urban environment with limited resources.
