Welcome to the San Francisco Orchid Society

Welcome to the San Francisco Orchid Society web site. We are lucky to reside in one of the best parts of the country for the cultivation of orchids in the home, greenhouse, and garden. It is our hope that our site, our meetings, and our members will spark your enthusiasm to give this most satisfying hobby a try!

Next Meeting: Tuesday, October 2, 2018 – 7:00 p.m.

October Speaker: Dr. Kay Klausing

Topic: Orchid Viruses: Practical Aspects of Dealing with Orchid Viruses

Dr. Kay Klausing with daughter Izzy

Dr. Klausing was born in Germany and didn’t start growing orchids until he was in college. The University of Konstanz where he received his Master and PhD in Molecular Genetics, had a lone Dendrobium kingianum specimen covering 2 huge baskets that had developed thousands of keikis due to being kept too warm. The gardener gave him a few keikis, and in so doing hooked him on orchids. His enthusiasm also spread to his friends and after a few years most of them were growing divisions of Den. kingianums (and Kay still has the original division of that plant). In 1990 he moved to the US to do his postdoctoral work at UCSD and he gave his collection to his Father, who also got infected with the dreaded orchid virus (much to his mom’s dismay). One of the first things he bought in the US (before he even owned car) was an orchid at an orchid show by the Palomar Orchid Society. Since then his orchid collection has swelled to about 1000 plants with an emphasis on the Cattleya alliance – almost exclusively species. He grows plants in three greenhouses (cool, intermediate and warm) and one outdoor area (rupicolous Laelias) in the San Diego area.

Kay was a member of the German Orchids Society for many years and is a long-term member of the AOS and currently serves on the board of their conservation committee. He is a member of the San Diego County Orchid Society, which he now serves as president.

How to test for viruses

Orchid Viruses:  Practical Aspects of Dealing with Orchid Viruses

During his Masters and PhD work, Kay used a virus as a model system for his genetic research and, as such, he has had a long interest in and fascination with viruses. In his presentation he will give a brief introduction to orchid viruses, but will focus mainly on the practical aspects from the point of growing orchids. He will demonstrate on how to perform tests, share the test results for his collection and provide tips on how to prevent the spread of virus in a collection.

 

Skills Session at 7:00 pm: October 2nd skill session will feature virus testing by Kay Klausing. Kay will conduct tests and go over basic techniques and disinfection. Members are encouraged to bring in a sample of suspected orchid virus infected foliage (ideally in a ziplock bag), and we will test them as time permits.
