DVOS Monthly Meeting
Thursday, Jun 12, 2025, 07:00 PM
Contra Costa Water District, 1331 Concord Avenue, Concord, CA, USA
Our Speaker in June will be Mary Gerritsen
Mary has been interested in plants for most of her adult life, and has been growing orchids on and off for the last 40 years, despite several cross country moves as part of her “other life” as a biomedical scientist. Her passion for orchids was rekindled when she moved to the San Francisco Bay area in 1997 and attended an orchid show. Returning home with a few plants, she decided to join a local orchid society to learn more about taking care of them, and from these beginnings, her current passion grew exponentially! Now Mary truly has put her roots down, and has orchids in two greenhouses, five lath houses, her front porch, sun room, and anywhere else she can put them. Her collection of about two thousand plants, mostly species, is rich in masdevallias and other miniature orchids of many different genera. Mary has traveled extensively to see orchids in situ, including many countries in Central and South America, Southeast Asia, as well as Australia, Papua New Guinea, South Africa, Madagascar, Europe & Mediterranean islands, the USA and Canada. She has co-authored six botanical books with co-author and photographer Ron Parsons “Masdevallias, Gems of the Orchid World”, “Calochortus, Mariposa Lilies and their Relatives”, “A Compendium of Miniature Orchid Species” (a two book set), “A Bay Area Guide to Orchids and their Culture” “The American Orchid Society Guide to Orchids and their Culture”, and the recently released “The Compendium of Miniature Orchid Species, 2nd edition” (a four book set).
Mary has served as president and vice president for both the Peninsula and San Francisco Orchid Societies, and is currently president and chief executive officer of the Orchid Conservation Alliance and a director of the Orchid Digest.

President's Letter
Dear Orchid Members,
I want to take a moment this month to talk about something we all experience—failure.
When I first started growing orchids, I believed success meant getting everything perfect. I obsessed over watering schedules, light levels, humidity, and repotting methods. And yet… I still lost plants. I still watched buds blast, leaves yellow, and roots rot. I was discouraged more times than I can count.
But here’s what I’ve learned: every failed orchid taught me more than any success ever did.
That overwatered Phalaenopsis showed me the importance of root health. The Cattleya that refused to bloom reminded me to check my light levels. And the Dendrobium that finally thrived after three years of struggle? It taught me patience.
Orchid growing isn’t about having a flawless collection—it’s about learning, adapting, and enjoying the journey. Each mistake is a stepping stone to better understanding, and every challenge is a chance to grow—not just for the plant, but for us as growers too.
So if you’ve lost a plant recently or are struggling with one now, you’re not alone. Don’t be afraid to ask questions, share your experiences at meetings, or reach out to fellow members. That’s what our society is for—supporting each other through the ups and downs.
Let’s continue to learn together, grow together, and yes—occasionally fail together.
Warm regards,
George Su
President
