Growing orchids in the great outdoors

The Sonoma County Orchid Society on Tuesday will help you make your orchids weather proof –– able to thrive outside the comfort of your home. Orchid specialist Mary Gerritsen will talk about creating suitable growing areas, micro-climates and how to cope with heat and cold. She will also delve into a survey of popular orchids that are grown outside year-round in different parts of the San Francisco Bay Area. There will be orchids for viewing and purchasing. Gerritsen has been a fan of orchids since her post- doctoral days in the late ’70s in San Diego. In her spare time she travels as much as she can to see orchids in habitat. In the past 12 years, Gerritsen has traveled to 15-plus countries to track and/or photograph orchids. She has also written articles for orchid magazines including Orchids, Orchid Digest and the Orchid Review. 6:30 p.m., Santa Rosa Veterans Memorial Building, 1351 Maple Ave., Santa Rosa,
