This was a year of surprises and challenges, and here we are in December, getting ready for the holidays. For SCOS, it was another year of fun events such as the potting party, barbecue & auction, bus trip, and ice cream social/bingo...along with the challenging Kincade fire. So sit yourself down, give yourself a big pat on the back and relax for a few minutes. If you’re wondering what you need to do for your orchids, just a reminder to stop watering those plants that need a dry winter rest. The monthly to do list at the end of the newsletter is a great reference. Last night’s cold temperatures found me bringing in a few laelia crosses and whisking the corms of my tuberous begonias into the potting shed.
This morning, still stuffed from a cornucopia of Thanksgiving fare, it’s time to turn our attention to our upcoming Holiday Party on December 10th which we have instead of our regular monthly meeting. Once again, Billie has come thru as our angel and arranged a lovely evening full of great company, scrumptious food, holiday cheer, beautiful decorations and live music. Please reach out to someone in the Society who might be staying home not wanting to come by themselves or drive after dark. Please let them know that we look out for one another, and at this time of year, some of us need the encouragement to get out of the house. Bring your friends and neighbors even if they don’t know a phalaenopsis from a phragmipedium.
It never ceases to amaze me how many hardworking members we have. I want to take a moment to thank everyone who has held an office, a position, or helped in the smallest way to make this Society function so smoothly. Sure, we have had some hiccups, but someone always steps up to save the day. It takes all of us to keep the SCOS running and succeeding. When we work together, we can do some amazing things.
So, talking about working together...you guessed it...our spring show & sale Exploring Orchids is coming up in just 4+ months on March 27-29. We need everyone to help with publicizing this event. We will email everyone an electronic postcard, and we ask that you forward this to everyone on your local contacts list. We believe this will be more efficient than driving around town in our carbon belching cars stapling paper posters to telephone poles! We also ask that you post our show postcard to your Nextdoor account or HOA bulletin board or other sites to publicize the show. We will still need you to distribute the printed postcards to places you visit. Also, we still have a few chair positions we need to fill. So please step up to organize the pasta party, or design and build the Society display. Sign-up sheets for volunteer positions on the days of the show will be available starting at the January meeting.
Lastly, I would like to thank Jonathan Robbins for his talk on orchid growing at our November meeting. It was practical and down to earth, easy to understand and a great talk for the newbie or the expert. Our stop at Flori Culture on the bus trip this summer was a special treat, allowing everyone to get the pots, bark, hangers, trays, media, fertilizer, bug spray, and all those necessities we need to be successful in orchid culture. Along with orchid growing supplies, Jonathan also brought a selection of unusual hoyas, bromeliads and “interesting oddballs”. We hope to see him as a vendor at our show.
I hope you and yours have a wonderful holiday!

Our Annual Show & Sale - Exploring Orchids - March 27-29
The theme is Exploring Orchids. Planning meetings have been held for the past 3 months. Many chair positions are going to filled by those who did the jobs last year. We'd like to see other members learn the various positions, so if you are willing to learn, please contact one of the chairs below who will gladly train you. We still need chairs for these key positions:
The Board agreed to raise the admission price from $8 to $10. A $2 off coupon will be in the Press Democrat and our postcard will also be good for $2 off.
Sue Hayes needs strong boxes for the plant hotel.
SCOS Boutique: Start collecting garden related items for sale in the boutique which is always a popular spot. Take some cuttings of your non-orchid plants and pot them up for sale.
Silent Auction: June Maiden and Amber Powner need items for the silent auction. Please solicit restaurants, wineries, nurseries, artists, misc service providers for gift certificates or actual items which will be auctioned off on the silent auction table. Get creative - put together a gift basket. New items only - re-gifting OK!
Promotion: We still don't have a chairman, so the job will be split up. Karen W. has scheduled ads with the Press Democrat. Ann Possinger and Haili Marshall will send notices to local event calendars, nurseries, other orchid societies. And we need you all to do things like send out emails to all your friends; post on your Facebook page; hand out postcards to places you visit; tape postcards to inside of your car windows. Please share any other ideas you have.
Vendors: Last year we had 14 but 2 bailed at the last minute so we had 12. Gary's goal this year is to have 15 - 5 have committed so far.
The next planning meeting will be Thursday, 1/16/20 at 7pm at the home of Ann Shippey,
2643 Spring Oaks Drive, Santa Rosa. Thank you Ann for hosting these meetings.

NOTES from the AOS FALL MEETING in Florida Oct 18-20 (Thank you, Nancy McClellan)
- Following a successful membership drive, AOS membership is at 10,498 members.
- A Librarian has been hired for the Fairchild Library.
- The nominating committee proposed the slate of officers for the next term. Susan Wedegaertner and her slate will step down following the Spring 2020 meeting, and the newly elected officers and Board will take up the reins at that time. Watch for your ballot.
- The annual audit of AOS’ financials found no significant problems or issues. Good news.
AOS’ new Orchid Pro has been launched and is included with your membership. It is web-based, so no downloads or software. And it can be accessed from your IPhone, Mac, anywhere you access the internet. OrchidPro is an easy to use online orchid program, with access to over 95,000 photos of award-winning orchids, plus exclusive award data, and in-depth genealogy (family trees, progeny, species makeup, parents etc.) IT is already working on future releases of OrchidPro, which promise to be more robust, and to include non-awards photos and data, and other features requested by AOS’ member community.
The AOS Spring 2020 Members’ Meeting will be held at the Embassy Suites in downtown Sacramento, hosted by the California Sierra Nevada Judging Center, April 16-20, 2020. Be sure to save the dates! You’ll hear lots more about this in January.
Spring 2021 will celebrate AOS’ Centennial, with a huge celebration at the new Biltmore Hotel in
Coral Gables, Florida. Mark your calendars for April 8 & 9, 2021. Work is progressing on a centennial book, a historical record of AOS’ first 100 years. And a new seedling cross will be introduced to commemorate the centennial.

For The Novice - Why Orchids Need a Drop in Nighttime Temperature
By Sue Bottom
Have you ever wondered why all the books say that many orchids need a 10 to 20 F (about 5.5–11 C) drop in temperature from day to night? Lower nighttime temperatures are critical for good growth and flowering because there must be a proper balance between photosynthesis and respiration for a plant to grow and bloom well.
ORCHIDS BY DAY During the day, your plants are busy:
• Making Food. Your plants are busy using solar energy in a process called photosynthesis. Light is absorbed by the chlorophyll in the chloroplasts and the carbon dioxide absorbed by the plant is converted into chemical energy in the form of sugars and starches.
• Using Food. Your plants consume their energy reserves in a process known as respiration. The food reserves of sugars and starches are used to maintain existing tissue as well as produce new growths, flowers and seeds.
By Lynne Murrell
CULTURE CONNECTION continued
ORCHIDS BY NIGHT At night, photosynthesis stops but growth and respiration continue drawing on the energy reserves created during the day. Respiration occurs more quickly at higher temperatures than at lower temperatures. At lower temperatures, it is possible for the energy consumption to be less than energy production, allowing the plant to store energy for future use, including flowering. If night temperatures are too high, food is used faster than it can be made so growth is poor and orchids do not flower or they flower poorly.
PROVIDING LOWER NIGHTTIME TEMPERATURES Providing cooler nighttime temperatures can be problematic if you are growing indoors in a climate-controlled environment. Perhaps the best alternative is a programmable thermostat or manually turning the thermostat down at night. Orchids growing by a bright window will be a few degrees warmer during the day from solar gain and orchids growing by an open window may be a few degrees cooler at night in winter. Where possible, you can provide lower nighttime temperatures if you grow your orchids outdoors or on a screened porch during the warm season.
FLOWER INDUCTION BY NIGHTTIME CHILLING Many orchids require a significant day–night temperature difference to induce flowering. Winter-blooming phalaenopsis require a 15 F (8.3 C) drop in nighttime temperature for two or three weeks to initiate their flower spikes. Cymbidiums and dendrobiums can require an even larger temperature difference. Dendrobium crumenatum is an interesting species that opens all its blooms simultaneously eight or nine days after a thunderstorm; some believe this is a result of the cooling effect of the evaporation of rainwater.
ZYGOPETALUMS CRAVE COOLER NIGHTS I have long loved zygopetalums with their bluish purple, green and bronze flowers and incredible fragrance, although they have tended to be very short-lived in my care. I have tried growing them in a wide variety of light conditions and potting mixes. Knowing that they like cooler conditions than we have in St. Augustine, I tried the old grower’s trick of growing them in sphagnum moss in a clay pot dropped in a second clay pot to keep them a little cooler from the water evaporating from the porous clay. They grew better, but still struggled. I was telling Fred Clarke of Sunset Valley Orchids my tale of woe and he told me to get them out of the greenhouse and under the shade of a tree. That provided a few extra degrees of nighttime cooling and the growth rate exploded over the summer. I was treated to more zygo blooms than ever before.
Understanding your plant’s metabolism gives insight into how best to grow it. Cooler nighttime temperatures allow your orchid to store, rather than consume the food it manufactured during the day. This stored energy can then be used by the plant to produce flowers. Next to insufficient light, insufficient day to night temperature change is the most likely cause of your orchid failing to bloom. If your plants are growing well and you are sure they are getting enough of the right kind of light, try dropping your night temperatures by a few degrees. You may be pleasantly surprised by the increase in flowers your plants produce. (November 2014, ORCHIDS, page 654.Reprinted with permission).

November & December
Growers of just about every level of expertise will have begun to notice autumn conditions by now. Days are becoming shorter, hence cooler; the sunlight has less intensity as a result of the sun's lowering angle, nights are longer and generally cooler. Plants are responding by slowing and ripening their growth in preparation for winter.
The first cultural change noticed should be a reduced frequency of watering, as the plants dry out more slowly. This is a function of both the reduced day length and lower temperatures, as well as the plants' slowing growth rate. Reduced water needs signal a reduced need for fertilization. Note that the key word is reduced, not eliminated. Feed less frequently and at lower dosage, but feed. Growths, made during summer's heat, and relatively soft and green, will be ripening -- hardening -- in preparation for a brief period of rest (in many cases).
Many of these ripening growths will have a sheath, presaging the coming winter or spring flowering season. In some cases, these sheaths will have been evident since as early as July. (Early sheath development does not mean early flowering on plants with winter-spring seasons.) You may notice that some of these sheaths are showing signs of yellowing. This is not abnormal. Autumn's more pronounced temperature fluctuation can lead to water condensation inside the sheath, hastening the normal process of senescence, so yellowing sheaths can be left on the plant only so long before they must be carefully removed to preserve the bud primordia within. Water condensation left unchecked can rot the bud primordia. The sheaths can be safely removed by slitting open and peeling down toward the pseudobulb.
One can almost hear a sigh of relief from all of the cool-growers, from masdevallias to odontoglossums. As day temperatures decline, one can see a noticeable improvement in these plants. Shorter days and lower light levels do not seem to bother them. Repot before winter arrives.
Finally we begin in earnest the main cymbidium season. Cymbidium ensifolium can give some early and fragrant hybrids, but it is now that the bulk of the crop will be flowering. The season lasts for about seven months, adding color to any collection. Miniature varieties will peak for the next three to four months. There are three important things to do: stake inflorescences ramrod straight for best presentation, watch for slugs and snails (especially just after a rain), and fertilize with a mild balanced formula regularly.
Oncidium crispum Complex
This is the season for plants in Oncidium section crispum from Brazil to shine. Extremely vigorous hybrids come in wide varieties of markings dominated with chestnut and brown and butter yellow. Give plants high light to produce strong upright inflorescences. The pseudobulbs should be plump, so do not let the plants dry out while they are in bloom. Later, plants will enter a dormant period.
The flowering season for the "toads" or "bulldog" paphs is just getting underway. These cannot be grown everywhere, but where cooler summer nights allow their growth, there is no longer-lasting or more exotic display than these. Paphiopedilums are, in general, not heavy feeders, and it is especially important with this type to reduce nitrogen levels now for best flowering and spike length. Be watchful for water accumulating in the growth around the sheath, or for the late-season warm spell, either of which can lead to the sheath's rotting. As the spikes emerge, do not change the orientation of the plant toward the light, as this can lead to a crooked or twisted spike.
While paphiopedilums rarely like to dry out entirely, water needs are significantly reduced beginning now. Overwatering at this time of year can quickly lead to root rot or erwinia problems. Now is the time to practice good sanitary practices in your greenhouse or growing areas, as pest and disease problems have a way of multiplying rapidly in the darker and more crowded conditions that generally mark the winter growing area. With paphiopedilums, especially, "cleanliness is next to godliness" and if the growing area is littered with old foliage, weeds and dying flowers, keeping the plants alive and flowering will be next to impossible.
Shortening days and cooler nights are the signals for inflorescence initiation in phalaenopsis. In more northern climates, or on the west coast, growers have already begun to see the early inflorescences that may be ready for Christmas. In the eastern areas, nights in the greenhouse will now be in the low to mid 60s, depending on the thermostat setting, so the first of our phalaenopsis will not begin to bloom until Valentine's Day at the earliest.
A reduction in nitrogen levels will go a long way to giving the best possible spiking, as will a boost in potassium and phosphorus. In other words, a "bloom booster"-type fertilizer is definitely indicated in the next few months. Disease and pest problems are best dealt with now, especially as mealybugs hide in the bracts and flower buds. Once they have established themselves, they are difficult to eradicate, and flower damage or crippling results. Potential disease problems can be dealt with by the application of a copper-based compound to control/alleviate rot problems before they start. There is nothing more frustrating than to have shepherded your plants through a growing season, only to have them decline before your eyes.
Whereas the general decline in temperatures is beneficial to cool-growing orchids, it is not for vandaceous plants. The only cold-hardy member is Neofinetia falcata. Orient your plants in such a way as to take advantage of as much light as possible. This can be a problem in northern latitudes. Reduce watering and feeding schedules.
The AOS thanks Ned Nash and James Rose for this essay.
Neofinetia falcata will thrive in cooler temps and produce graceful vanilla-scented flowers.
Tis the season for orchid shows all over the US. Please see the AOS event calendar at www.aos.org for the complete listing of events.
