Hundreds of plants, a free tool-sharpening station, and a farmers market stocked with organic produce are landing at Balboa Park's Casa del Prado on Saturday, September 12, as the University of California Master Gardener Program of San Diego County holds its annual Fall Plant Sale. The event runs from 9 a.m. to 3 p.m. in Room 101 and Patios A and B, and admission is free.
According to the San Diego Union-Tribune, shoppers will find fall garden vegetables, drought-tolerant plants, native plants, and unique houseplants for sale, alongside handmade garden art and bird houses. The paper reports that a section dubbed the Green Elephant sale will offer repurposed garden tools, equipment, pots, and garden decor, while a farmers market on site will sell freshly picked organic, locally grown fruits and vegetables. The Union-Tribune also notes that the program's tool sharpening and cleaning team will clean and sharpen one working pair of pruners or loppers per shopper, and that a plant daycare service will watch shoppers' purchases, while children's activities are listed separately, per UC Agriculture and Natural Resources.
Parking is free for San Diego residents, with a shuttle running about one block from a nearby lot, though the Union-Tribune notes paid parking is also available closer to the event for those who don't want to walk. Organizers advise bringing a cart or wagon to haul purchases back to the car, a detail UC Agriculture and Natural Resources includes in its event guidance. Decorated succulent pumpkins will also be on sale, a seasonal touch UC Agriculture and Natural Resources highlights among the day's offerings.
Free Talks Cover Everything From Composting to Rare Fruit
Free Talks Cover Everything From Composting to Rare Fruit Throughout the day, UC certified master gardeners will host free garden talks without registration required. Topics span vegetable gardening, accessible gardening, irrigation, seed starting, tool care, rare fruit growing, California native plants, food preservation, and landscape design, according to the Union-Tribune. The Master Gardener Association of San Diego County also lists a talk schedule.
UC certified master gardeners will also run demonstrations in gardening techniques and flower arranging, and staff informational exhibits where visitors can get gardening questions answered with advice tailored to San Diego's local habitat. That kind of hands-on troubleshooting mirrors the group's free hotline, a service the Master Gardener Association of San Diego County says fields more than 5,000 home gardening and pest management questions a year, with volunteers typically responding within 24 to 48 hours.
Why Fall Is Prime Planting Season in San Diego
Why Fall Is Prime Planting Season in San Diego The sale is scheduled for fall.
Proceeds from the sale help fund community activities involving volunteer master gardeners, per the Union-Tribune, work that extends well beyond the one-day event. Those volunteers participate in school and community garden projects across the county, and more than 60 school consultants work with teachers.
From Memory Care Gardens to a County Demonstration Plot
Volunteer master gardeners also bring sensory-focused gardening experiences to memory care facilities around San Diego County, the Union-Tribune reports. That effort is part of the group's sensory-gardening work, according to UC Agriculture and Natural Resources.
The nonprofit's reach also extends into government partnerships. In October 2021, the UC Master Gardeners teamed with San Diego County to build a 20-by-20-foot demonstration garden at the County Operations Center in Kearny Mesa, according to the County of San Diego. The organization was founded in June 1983 with 34 UC-trained volunteers, per UC Agriculture and Natural Resources.
Casa del Prado, the sale's venue, carries its own history. The building is a historic reconstruction of a Spanish Colonial Revival structure originally built for the 1915 Panama-California Exposition, according to the City of San Diego. It's the same Balboa Park venue that hosted the Plumeria Festival's 400-variety bloom show in September 2026.
Home gardening in San Diego also sits atop a much bigger agricultural picture. Full details on the Fall Plant Sale, including the day's talk schedule, are posted at mastergardenersd.org/plant-sale, per the Union-Tribune.
