Welcome to the Palomar Orchid Society Website!

 General

• In general, most orchids should still be kept fairly dry in winter even during warm periods.  If you grow on the coast near the ocean, humidity is usually higher so occasional misting (with pure water, if available) or light watering in extended periods of warm or Santa Ana conditions may be warranted. If you grow further from the ocean, where orchids experience even warmer temps and low humidity and are openly exposed to Santa Ana winds, then you may need to mist and water more often to avoid dehydration, but avoid watering excessively.  Too much water will encourage plants to send out new growths, which will not fare well when the weather turns cold again.  
• When you do water, do so in the morning and avoid wetting buds and flowers to minimize botrytis (fungal) spotting.  Also keep tabs on the ten day weather forecasts and avoid watering if cooler and/or wet weather is predicted. One wants to make sure orchids are kept on the dry side to allow them to tolerate the cold winter nights we tend to experience in Southern California.  If February brings more normal, cooler weather than January, cut back on water and avoid fertilizing as cooler days and nights prevail.
• Maintain cold-sensitive, warm growing orchids (phals, paphs, tolumnias, most vandas and warm growing dendrobiums and cattleyas such as violacea, dowiana and their hybrids) inside or in a greenhouse to protect them from night temperatures below 50o; however, watch under leaves for spider mites and other pests that flourish under dry, less humid conditions.  An excellent article on ‘Cold Tolerance of Orchids’ by Sue Bottom of the St. Augustine Orchid Society can be found on their website.

Alan KochWe are delighted to welcome as our first speaker for the 2013 season Alan Koch of Gold Country Orchids in Lincoln, CA.  Alan will talk on “Species Habitat and Hybrid Culture”and will teach both novice and advanced growers how to link the way a species grows in the wild with how to grow the species and it’s associated hybrids in your collection. This program is strong on orchid culture and will help us improve the ability to grow and successfully bloom our own orchids.  Alan will provide the plant table as well as offer additional plants for sale at the meeting.  

Alan owns and operates Gold Country Orchids (www.goldcountryorchids.com), where he specializes in miniature and compact Cattleyas. Alan started growing orchids in 1969 with 3 Cymbidiums given to him by an aunt.  While in college he became interested in other orchids and discovered many would grow outdoors in Southern California.  He has moved five times as his orchid obsession has led to the need for more growing space.  With the last move, he purchased 10 acres of land in Lincoln, California for his 250,000 orchids.     Read more »

Gilbert J. HoStanhopeas are the upside-down jewels of the orchid world. They are not often cultivated but fairly easy to grow in our Southern California climate with a few basic rules. These plants are highly fascinating as their pendant flowers are among the most highly evolved and specialized of all orchid flowers. The flower spikes emerge through the bottom of the growing basket to hang freely like birds in flight.  With an emphasis on the roughly 70 species currently recognized, Gil's talk will cover basic information about different Stanhopea growing conditions in nature and the origins of Stanhopea collecting and identification. Hybridizing stanhopeas will be mentioned briefly and the talk will conclude with an overview of cutlure conditions for growing Stanhopeas in our Southern California area. This section will serve as this month's culture class.   Read more »
