We are having a big orchid repotting party!
It will be a hands-on workshop and demonstration of repotting a phalaenopsis orchid. Everyone will receive an orchid ready for repotting. You will also receive expert direction from experienced growers to help with the repotting process. You will get tips to make your orchid thrive and bloom!
Sonoma County Orchid Society will supply plenty of phalaenopsis hybrid orchids. We will also supply bark, pots, tags, and gloves. (SCOS members, please bring a pair of sterilized clippers.)
We will have everything you need to get your orchid off to a great new start! Once you have repotted your new orchid, you will take it home to enjoy!
New members and guests don’t need to bring anything!
SCOS Members – Don’t forget to bring your gorgeous blooming orchids for Show and Tell! Feel free to bring snacks to share with attendees.

Mary Gerritsen will speak on the “Orchids of Sikkim“. Sikkim is a premier orchid habitat in India, boasting over 500 species ranging from subtropical to alpine zones.Â
Mary has been interested in plants for most of her adult life, and has been growing orchids on and off for the last 35 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 the Peninsula Orchid Society (POS) to learn more about taking care of them, and from these beginnings, her current passion grew exponentially!
New members and guests don’t need to bring anything!
SCOS Members – Don’t forget to bring your gorgeous blooming orchids for Show and Tell! Feel free to bring snacks to share with attendees. Everyone who brings a snack gets a free ticket for the opportunity table plant drawing which Mary is providing.
