Annual Meeting, Potluck Dinner and Gary Baker Service Award

June is our Annual Business Meeting and where we traditionally have a Potluck Dinner before our society goes on its two month summer hiatus. 


This meeting's Orchid Basics presentation will be expanded into a group discussion to cover a couple of subjects.  The first part will be a discussion on how to grow and bloom our Trader Joe or raffle table Phalaenopsis.  The next part will be a discussion on which Orchids will do best outside for the Summer and how to care for them.


A highlight of the evening will be the announcement of the winner of the Gary Baker Service Award. This award is given annually to the person who has contributed the most to the overall goals of the society in the prior year. This special honor goes to a recipient who is selected by the board from nominations made by the general membership. Honorees are presented with a crystal perpetual trophy engraved with their name.


Dinner = What should you bring?


To kick off the festivities the society will provide a nice cut of meat or poultry. It will also provide plates, utensils and napkins, but if you're feeling green, bring your own.  There's a kitchen for quick cleanup afterwards. Members can bring additional food: a main dish, side dishes, salad, drinks or dessert to share for our Potluck Party. For reference and to help decide what delicious food to bring, you could use the handy list.  If your name starts with:


A - I = bring dessert or beverage

J - R = bring a salad or vegetable dish
S - Z = bring a main dish


Consider this a guideline only.  If you have a dish you are known for, or just want to share something special with others, please bring that instead.


Display Table:

Bring your blooming Orchids so everyone can enjoy them.


Sales Table:
Members may bring up to 10 plants to sell.  Include an extra tag with your name and the price in the plant.


The raffle will be held as usual.  Win a new orchid for your collection while supporting the Scholarship Fund.


NWOS Library: 

If you'd like to check out a book or tape from our Library, please contact our Librarian Joe Grienauer a minimum of 2 weeks before the next meeting.  Besides email, you can give Joe your request at any meeting.  For a list of library items Click on the Library link at the top left of this page or click HERE.

Monthly Checklist for July and August   

The AOS thanks Ned Nash and James Rose for this essay

Cattleyas this month require careful attention to their watering and fertilizing needs owing to characteristically high temperatures. Evaporative cooling is a must in areas of the country where it is effective. Where it is not (the more humid regions), care needs to be paid to proper venting to keep temperatures within reason. Bottom vents in conjunction with top vents provide enough rising airflow to help keep plants cool. Increased air flow lessens humidity and dries plants out more quickly, necessitating more frequent damping down and watering, in areas where high humidity is not a problem. Higher light and heat indicate more fertilizer. The growths your plants are making now are the source of this autumn, winter and spring's blooms, so applying adequate fertilizer this month is the best way to ensure future blooms. Higher temperatures and humidity may also lead to fungal or bacterial rot problems, so it is important to closely observe your plants for any early indication of problems. Pests are also at a high point this month for the same reason.


Cooling and air circulation are especially critical in these two months to prevent stress and avoid disease problems. Watering needs to be closely monitored to ensure that plants do not dry out. Warmer-growing hybrids will be at the peak of their blooming, with attention needing to be paid to staking of spikes. Look for water lodging in growths, which can rot emerging spikes and lead to the loss of the entire growth.

Beallara Diana Dunn 'Newberry' is a good example of the colorful patterns that Oncidium intergeneric hybrids offer.

Most, if not all, potting should be complete by now. This month and next are when these plants achieve their maximum growth. This growth will be that from which they set their spikes for the coming season. The more leaves the plants grow, the better potential for spiking will be realized. Growers in cooler areas such as the Pacific coast have the advantage this month, should they choose, of cooling for early season spikes. Lots of heat and light call for liberal applications of water and fertilizer.

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.


Oncidium intergenerics
Many of the intergeneric crosses between odontoglossums and oncidiums, such as Odontocidium, Wilsonara and Colmanara, will be blooming now. Take special care to train the spikes for best floral display. Keep plants under fairly shady conditions. Watch for snails and slugs.

Philippine species, Euanthe sanderiana, rewards growers with massive heads of flowers at the end of summer.

High-elevation Plants
For cooler-growing plants, such as masdevallias, other pleurothallids and the like, the next few months will be a challenge. During the hottest times, keep your plants more shaded and be sure to keep the humidity level much higher. Do not let plants dry out. Delay any potting until the weather cools.

Plants will be growing quickly now and really enjoying the hot humid days so similar to their native habitat. Watch for pests though, as many of these also enjoy the same conditions as the plants. Check flower spikes so that they can extend unimpeded for the best flower presentation later.

Report from the May Meeting

Walter Orchard


Our meeting began with an Orchid Basics demonstration of various staking techniques by Diane, Cylvia and Abigail. 
Then Abigail welcomed new members and visitors, made several announcements, called for volunteers for the Show Committee, Nominating Committee and for a host for our August Picnic. 

Our librarian, Joe, had a special selection of books available that worked well with our speaker's topic of growing Disas. 

Kathy Murray announced that this year's Scholarship would be awarded to Ryo Okubo.  This will be for the next phase of his studies into the interaction between Aedes mosquitoes and the orchid Platanthera obtusata.  Many of you may remember his fascinating talk last June.  We look forward to hearing the results of his latest research into this special mosquito/orchid relationship.

George Grantham gave thanks for everyone who helped with the Oregon Orchid Society Show and who lent blooming plants.  A special thanks to Lillian Otani for her help transporting the plants and assisting with the exhibit takedown.


Our speaker, Wally Orchard, gave a very interesting and informative talk about Disas from his home country of South Africa.  These very colorful and beautiful orchids grow mostly on moist, mossy cliff faces in bright light, so it's important to grow them wet.  He showed their large underground tubers, roots and stolons that put forth new plantlets.  He described their growth cycle with 'A year in the life of a Disa'.  Then in what he called 'heavy science', Wally showed us the complex chemicals involved in color inheritance.  It was fun to learn how one species was butterfly-pollinated and another was fire dependent.  After showing us many great photos of hybrids, he concluded with a review of their culture.  With special attention to their needs, we can be rewarded with these lovely summer bloomers.

Orchid Basics staking demo. Diane showed how to create wire supports and a
variety of clips and strips to hold your bloom spike.  Cylvia tackles a rangy oncidium
and expertly arranges the multiple spikes.  Abigail enjoys a bit of a struggle with
a wire. She showed us the cool spiral support that works so well for weak spikes.
