  The Guadalupe Demo Garden is a typical 20 by 20 ft plot in a large community garden. Our goals include showing how much produce can be grown in a small area and demonstrating good gardening principles such as soil amendment, efficient watering, mulching, crop rotation, and attracting beneficials. We grow a wide variety of vegetables, herbs, and flowers year round and conduct public education classes throughout the year. In the period, July 1, 2014 to June 30, 2015, we donated 483 pounds of produce from our small plot to Martha's Kitchen of San Jose.


The GDG Master Gardener team


On November 1, 2008 the Master Gardeners of Santa Clara Signage at Guadalupe Garden County were handed the keys to plot #20 at the new, urban Guadalupe Community Garden within the Guadalupe River Park and Garden complex to use for research, demonstration and education. The Guadalupe Community Garden is the first community garden in California to be watered exclusively with recycled water. Our partners in this high visibility project are the Friends of Guadalupe River Park & Gardens, South Bay Water Recycling, and Santa Clara Valley Water District.

Guadalupe Garden, early May 2009 The team’s first activity was to attend a required training session on how to use special recycled water equipment, to keep recycled water separate from potable water. (We have been involved in the periodic testing of the soil and plant material to determine the effect of recycled water.) We then began to prepare the plot by digging down to the base soil that had been compacted by construction equipment, breaking through the hardpan, removing many, many rocks, amending the soil with soybean meal and alfalfa pellets, partitioning the beds and finally burying kitchen scraps as compost. The first plants (tomatoes, peppers, eggplant and cucumbers) were planted on April 13, 2009; more followed in early May. The official opening ceremonies for the Guadalupe Community Garden took place on Friday, August 14, 2009.
