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.

Peter started growing orchids over 40 years ago, but then stopped due to school and starting a career. It wasn’t until about 25 years ago that the orchid “bug” came back, and he is now heavily involved once again! He is an accredited judge with the American Orchid Society, and a hybridizer of mini-catts. He enjoys meeting with other orchid enthusiasts, and can often be found at various orchid shows and societies around the country.
Due to limited growing space, Peter likes to specialize in miniature orchids, both species and hybrids, and has received numerous AOS awards. His interests in orchids include Dendrobiums, Angraecoids, and Neofinetias. He is also known as “Mr Sophronit is” as he has a passion for growing and collecting them . He maintains a collection of a several thousand orchids at his home in Southern California in 3 small greenhouses, outdoors, as well as an offsite greenhouse.

Program : Two Sides of t he Sam e Sun by Carol Klonowski
Two Sides of t he Sam e Sun: Sum m er & Wint er Care for Orchids aims to encourage hobbyists to understand the many species and hybrids from the orchid world that have distinct requirements at certain times of the year. This program explains the need for special care during both warm, active-growth seasons and the coming fall and winter months.
Carol Klonowski has been growing orchids since the 1980’s when a friend in Berkeley, California gave her a cattleya, and it bloomed out with three big, dark lavender flowers and an intoxicating fragrance. She built an entire greenhouse in her backyard to accomodate the precious plant, which only led her to buy more orchids. Then another friend gave her a gift membership to the Orchid Society of California, and it’s been a serious hobby and passion ever since. She can recall going to monthly meetings where orchid legends such as the late Frank Fordyce would be available to answer the many questions an eager hobbyist could ask.
Carol is currently the President of the Orchid Society of California and a fully Accredited Judge with the American Orchid Society, Pacific Central Judging Center. She is a former Trustee for the American Orchid Society and writes for Orchids Magazine.
Join us for dinner at 5pm with Carol Klonowski at Sea Thai Bistro in Montgomery Village, 350 Midway Dr, Santa Rosa at 5pm. RSVP to David Parkinson.
