Dale got the orchid bug in his early teens in Phoenix, but after moving to the Bay area in 1976 he became acquainted with Rod McClellan’s orchids, and soon his kitchen window was brimming with orchids. A move to Santa Rosa in 1989 afforded an opportunity to house his rapidly growing orchid collection in a backyard greenhouse. In 1999, he and his wife completed construction of a new greenhouse and home in Petaluma. Austin Creek Orchids was established in 2001. In the past few years, he has focused largely on Paphiopedilums, although he grows many other genera including Angraecum, Bulbophyllum, Cattleya, Dendrobium, and various vandaceous species and hybrids.

"Terrestrial Orchids of Western Australia - Dragons, Fairies, Spiders, and Other Elusive Creatures" by Dale Martin.

Skill Session with Susan Anderson at 6:40pm - How to Get Your Orchids to Bloom!
This presentation is based on a trip that my wife (Lynne) and I took to Australia in September 2015. Western Australia has more more than 400 orchid species and dozens of subspecies and natural hybrids. 100% of those are terrestrial and therefore tend to be much different than the orchids that we commonly associate with Australia (or grow in Northern California), such as Dendrobium, Sarcochilus and Phaius. Generally, the orchids of Western Australia have symbiotic associations with Mycorrhizal fungi to benefit their plant growth and development, often required throughput the entire plant life cycle, not just for seed germination and early growth phases. As a result, these plants are rarely seen in cultivation, even in Western Australia.

For all you members who didn’t go to the Auction and BBQ, you missed out! Sorry to say that, but it was a really fun event. If you’re a new member or just haven’t gone before, make sure you don’t miss it next year. When this group gets together they are funny! Alan Koch (auctioneer extraordinaire) is fantastic; totally worth the price of admission! Along with Alan’s entertaining stick you also get a bunch of great food too…I think I tried a taste of almost everything…Kathy Rathbun’s gluten free apple pie was one of the best I’ve ever eaten (I wanted to eat the WHOLE thing); and to everyone else who brought a dish, thank you - it was all delicious. I think some of our members are sneaking out to culinary classes instead of coddling their orchids…
Special thanks to Alan Koch for being the best auctioneer and for providing healthy, unusual, and great orchids for the event. If you’ve never experienced Alan auctioning off an orchid…he tells you some amazing things about the plants. So, you’ll learn while you help support the society.
Thanks to everyone who made the Auction and BBQ a success. To Jeanne for sharing her beautiful home & garden - what a spectacular place! She even ordered perfect weather! To Ann Possinger, who has now earned the title of Goddess for organizing. To Earl and Kathy Rathbun, without whom I would have been lost…and the infamous yak bell. To the ladies who ran the accounting table (they were so fast!) To our master of communications, Susan Anderson. To Dave Jackson for the BBQ'ing, and to everyone who helped set up, brought something, donated plants, and helped clean up….THANK YOU!!!!
I’d also like to thank Mary Nisbet, Susan Anderson and Tom Pickford for opening up their greenhouses to us in Bolinas. It was a long drive - Ann Conger and I went together, and we had a great time just getting there. Mary had a very unusual selection of plants for sale, some of which I’d never heard of, and some old favorites that were so beautifully grown and reasonably priced that I just had to bring home a few. I’d like to remind our members, new and old, that visiting these greenhouses is really eye-opening…I always learn so much. I saw a cymbidium that is the most unusual cymbidium I’ve ever seen….and the displays of orchids on cork oak logs…I mean tree size trunks covered with orchids and air-plants were spectacular!
One last note to new members or members who I haven’t met – please introduce yourself to me. I am happy to answer your questions about the society or orchids.

October is also time to start bringing indoors your orchids which summered outdoors. Your decision as to what and when to bring in will depend on the weather forecast and the temperature tolerance of your plants. Here are some guidelines from Sandra Tillisch Svoboda:
CATASETUM Most of these orchids are native to hot tropical areas and grow during the rainy summer months. After growths mature, temperatures can be reduced to 55 F at night, with day temperatures of 70–85 F .
PHALAENOPSIS These should usually be above 60 F at night and range between 75–85 F or more during the day, although night temperatures to 55 F are desirable for several weeks in the autumn to initiate flower spikes.
PAPHIOPEDILUM Paphiopedilums generally enjoy the same temperatures that we do in the home; ideally, 60–65 F at night. Paphiopediums can stand temperatures down into the 40’s F for short periods.
COELOGYNE This is a diverse group of plants with many different requirements depending on where the species grow. You first need is to determine whether the plants you have are cool, intermediate or warm growing.
LYCASTE Generally grow these orchids warm while actively growing: 60– 85 F, and cooler during autumn and winter, with a minimum night temperature of 48 F.
ONCIDIUM This group is generally considered intermediate to warm: 55–65 F at night and 80–85 F during the day. The exceptions to this temperature regime are those plants formerly included in Odontoglossum and their intergeneric hybrids. These plants are usually recognizable by their bright white or red, solid or patterned flowers. For these plants day/night temperatures should be 70-75/50-55 F.
DENDROBIUM This is another very large, widespread genus and to grow them well you need to determine to which group your particular plants belong. You can find a good summary describing the cultural requirements of the main groups here: http://www.aos.org/orchids/culture-sheets/dendrobium.aspx.
MILTONIA There are two distinctly different genera that are commonly referred to as miltonias. Those with star- or spider-shaped flowers are intermediate to warm growing and should be treated like similar plants in the Oncidium Alliance. The other genus, properly called Miltoniopsis , has flowers reminiscent of pansies and gives them their common name pansy orchids. Miltoniopsis will tolerate down to 50 F at night if kept on the dry side (but not bone dry).

Despite the shortening days and lowering angle of the sun, September can still be one of the hottest months. Water and fertilizer need to be in balance with heat and light. The alert grower will notice, however, that his or her plants are beginning to slow down a bit. Growths are maturing, and the sheaths are giving the promise of the next six-months' bloom.
Check plants for potting needs for the last time this season. Any in dire need should be potted, even some that may be on the cusp, as there is just enough of the growing season left to allow the plants to establish before the days start to get really short and cold.
This is the month for purples derived from Cattleya labiata breeding to flower. If you are short on flowers, look into this group. There is nothing that can quite match this type for beauty and fragrance. They are easy to grow, too.
Plants summered outdoors should begin to be prepared to be brought back into the winter growing area. Clean the plants up and be on the lookout for any pests they may have picked up during the summer. Treat as necessary.
This little-known and under-appreciated genus, which can have male or female flowers, is at its best in the autumn. Two of the spectacular varieties are Cycnoches loddigesii, with its large brown flowers resembling a prehistoric bird, and Cycnoches chlorochilon, the swan orchid. This last one has large, fragrant green flowers. The biggest problem, culturally, will be red spider mite infestations that require immediate attention. Plants are quite seasonal, requiring heavy watering in the growing season and then a drier dormant winter season.
Summer can be the most rewarding season for cymbidiums. Growths should be coming strong now. The leaves of the new growths are best when they are broad and fairly stiff. The color should be a light green to nearly yellow. Early flowering varieties should be showing flower spikes, so move the plants into a cooler area with lower light. For mid-season varieties, lower the dosage of nitrogen to assist in spike initiation.
monthly checklist Sept & Oct
the green swan orchid
This is a good season for hybrids of the Dendrobium phalaenopsis and Dendrobium canaliculatum types. Both are capable of putting on tremendous shows of long-lasting flowers. Fertilize with a low-nitrogen formula to promote the best flowers. Dendrobium phalaenopsis can get tall and top heavy, suggesting an attractive and heavy container would be appropriate for this type.
Dendrobium Burana Stripe is a popular
and easy phalaenopsis-type hybrid
Standard, green-leaved paphiopedilums begin to show their bloom sheaths this month. Late-season heat waves can blast these early sheaths, so be observant about proper cooling and air circulation. As with the rest of your plants that may have been summered outdoors, it is time to prepare for their move inside. Clean each plant and implement pest-control practices. Repotting, if necessary, is appropriate.
The bulk of this season's growth is being ripened this month, with growers in cooler climates seeing the first emerging inflorescences. Some night heating may be necessary in the cooler areas. Begin to watch watering more carefully, and reduce feeding proportionately with reduced watering needs. An extra dose of phosphorus and potassium, such as a bloom-booster or high-acid-type fertilizer, is beneficial.
Once known as Odontoglossum grande, this is a spectacular orchid with six to eight flowers up to 8 inches across. Often known as the tiger orchid, it has bright golden yellow flowers heavily marked with chestnut brown barring. The plants are beautiful with a grey-green cast to the foliage, which is borne on succulent pseudobulbs. It prefers hot and wet summers with cooler, even down to 40 F, dry winters. Grow under filtered light. Watch for snails and slugs that eat the flowers, pseudobulbs and leaves.
The AOS thanks Ned Nash and James Rose for this essay.
