No General Meeting minutes as the November Meeting was replaced by the Annual Auction
No Committee Meeting for November as the year was ending and the Christmas Party was fully organised
--------------------------------------------------------------------------------------------------------------------
JOAN FONG RIP
It is with great sadness that Nightcliff Orchid Society has been
told of the passing of Joan Fong.
A Life Member, Joan was a stalwart of our club and will be
hugely missed. No-one ever had to remind Joan about the
raffles: she always had them completely organised.
Joan also grew beautiful orchids and won Champion
Specimen with this well flowered Caulocattleya Pink Charm
NOTICES
1. Supper for the January meeting is traditionally
supplied by the Committee. All other slots are
vacant, so please sign up!
2. One social activity is already planned for
January but the rest of the year is fairly empty.
Please suggest ideas and/or activities.

2019 FROM THE VIEW OF NIGHTCLIFF ORCHID SOCIETY 2019 has to be one of Nightcliff Orchid Society’s best years ever. Some high points included: February A Workshop/social gathering at Warren’s home. This was noteworthy for the number of large plants brought along that needed dividing. March Another workshop/social gathering at Jill Rathbone’s home April A Pot Luck supper at Warren’s home and a chance to see his wonderful shade houses and orchids [and railway] May June 5|Page
Litchfield Orchid Club hosted the annual Orchid Spectacular at the Foskey Pavilion which again saw hundreds of visitors arriving to see champion orchids, purchase potential future orchid winners and then relax with a Cream Tea. July This year’s Royal Agricultural Show was again highlighted by the co-operation between NOS and LOC who jointly ran and operated the huge “Wheelbarrow Full of Goodies” Raffle. Donations from members were outstanding and showgoers clamoured to buy raffle tickets. Orchid entries were as good as ever and Sue McKeon took out Champion with her Den. Sweet Dawn August Nightcliff Orchid Society and Litchfield Orchid Club jointly hired a coach to take members for a trip to Dundee Beach Orchids followed by lunch [at cost] at the lodge of Dundee. More than 40 members attended and had a great day out as well as adding to their orchid collections. Thanks Tony!!!! 6|Page
September This year’s Spring Show was an amazing success with more visitors than ever before and the orchids behaving themselves by flowering at the right time to such an extent that the species Dendrobium displays were a sight to die for. October November The Annual Auction was well attended and fitted neatly into the time allowed for a general meeting. A profit of approximately $350 assisted with the members’ subsidy for the Christmas Party. December The annual Christmas Party was better than ever. 41 people attended and seemed to enjoy the evening immensely. The hampers/gift packs were the best ever [how this happens each year is unbelievable] and everyone went home overloaded with goodies courtesy of the hard work of Kerryn Steward, Vanessa and Nicole Kaye and Anthony Fuller 7|Page
Growing Orchids from Seed – Notes from Tammie
I was asked to share the method I use to successfully germinate orchid seeds. It took many attempts to get a
successful outcome – I would recommend you record each attempt to see what worked best for you, but don’t give up.
If I can do it, anyone can.
Harvesting of seed pods
An orchid fruit (a pod) is usually formed quickly but may take many months to mature. Harvest
when yellow or brown and almost cracking open. If you live in the orchid’s home country and
follow its natural cycle, take a note when the orchid fruit is mature. This is probably the best time
for germination (regarding temperature).
Storage of seed pods
Dry the capsule indoors and then use a pair of forceps to transfer the interior of the orchid
capsule to a small container such as an eppendorf tube. (I used a paper bag.) For successful
seed germination, act quickly, do not postpone transfer to growth media!
Media making (the fun and messy part)
40 g of mashed peeled banana (equivalent to half a small banana).
100 ml of fresh, peeled and crushed tomatoes (equivalent to 2 ordinary tomatoes).
10 g of agar (powder is preferable) buy at the Bagot Road Asian grocery store.
20 g of sugar.
1.2 g of thiamine (vitamin B1 from the pharmacy, 12 tablets 100 mg each, pound in a mortar first).
900 ml of tap water (should be distilled water if your tap water is dirty or above pH 7).
8|Page
Prepare the ingredients separately.
Mix all ingredients evenly using a household mixer.
Transfer the medium, while stirring, to the clean flasks. 1-2 cm depth is usually enough. (I used
jam jars, bought from Gateway Target store)
Close the lids softly so that air can go out (or they will explode in the oven).
There are three simple ways to sterilize the flasks:
1. Place the bottles on a tray in a pre-heated oven 150-180°C. Wait until you see bubbles and
then sterilize for another 10 minutes. For this technique you cannot use plastic lids.
2. Put the bottles with media in a big pan with boiling water just above the agar level. Put on the
lid and leave for 30 minutes. Although you only reach about 100°C, this may in many cases be
sufficient. Hospital sterility may not be the goal here, and we do not expect tough bacterial
spores. The goal is mainly to kill fungal spores and most bacterial cells.
3. Transfer the flasks to a pressure cooker and when steaming, leave for 20 minutes. With a
higher pressure the boiling temperature is higher, and so even bacterial spores will die. This is
the best option, although maybe not always necessary. This is what I did.
Let the flasks cool down until the next day and then tighten the lids. If you tighten immediately
you may have more condensation as you trap hot air which contains more humidity than cool air,
and there will be a low pressure inside causing difficulties to open the lid, which in turn may
result in contamination when trying to open.
Store the bottles in clean plastic bags to avoid contaminating spores covering the surface. If the
media start cracking or shrinking, they are too old and you should discard, clean and reuse
again.
You could sow the orchid seeds as soon as the medium is not hot any more, but it is better to
wait 5-6 days to check that the flasks are not contaminated by fungi which may kill the plants.
Sterilization and sowing of orchid seeds
Select a clean working place indoors, such as a metal bench (not wood) free of debris and
preferably cleaned with 80% alcohol (I bought a 70% spray bottle from JayCar, but have seen
it in Bunnings too) Use clean hands (wear gloves) and clean clothes. (I put on a painters
overall fresh out of the package from Bunnings) Do not bend over the bottles. If the growing
flask contains a lot of liquid on top of the medium, pour it out first. (this didn’t happen to me)
A professional laminar flow bench is preferable. It has walls and the sterilized air flow blowing
against you makes it hard for outside spores to enter the growing bottle. A laminar flow bench is

a big investment for a home gardener. Some simply use a fish tank (40 cm wide) which can be cleaned with alcohol. Turn it so the opening faces you and the glass wall becomes a barrier against airborne spores. The crucial point is those few seconds when the lid is open to add the orchid seeds. The golden role is to minimize the exposure time and to aim at highest cleanliness as possible. Take what you have and try. (I adapted a plastic storage container by cutting two round holes to put my covered hands through – the clip lock lid helped keep exposure down) . Surprisingly often you are successful without the expensive equipment. (I also had a container with a bleach solution on the side to wash my hands at every opportunity to keep them ‘clean’). Mix 9 parts distilled water + 1 part bleach (household, 5-6% NaOCl depending on brand, Bleach) + 1 drop detergent as many seeds repel water. We call this the sterilization liquid. Prepare 80 ml of sterile water per orchid fruit (boil water in containers like when you make the medium). Let the water cool down to room temperature. Prepare a disposal vessel for excess liquids. If you have a syringe go to A1. If you have no syringe go to B1. (buy syringe at Chemist) A1. Add the contents of one fruit into any vessel that will fit your 20 ml syringe. They do not need to be sterile, as the sterilization liquid will take care of that. A2. Add 10 ml of the sterilization liquid and mix gently. Wait 5-10 minutes. A3. If the seeds are heavy they will sink to the bottom and using the syringe you suck out and dispose the majority of the sterilization liquid before adding 20 ml sterile water. Suck up the seeds and the sterile water in a 20 ml syringe. Let the syringe stand up with the tip upwards for 15 minutes while the seeds sediment. A4. Press out excess fluid with one move without stirring the seed sediment, and fill the syringe with new sterile water. Repeat 3 times. A5. Before transfer to the growing vessel, concentrate the seed solution by minimizing the amount of sterile water. 4 ml remaining liquid is fine, and then you shake the syringe to stir up and mix seeds. Add a preferred amount (five droplets) to each flask with nutrient medium. B1. Add the contents of one fruit to any tall thin vessel like a perfume bottle. B2. Add 10 ml of the sterilization liquid and mix gently. Wait 5-10 minutes. B3. If the seeds are heavy they will sink to the bottom and you pour or suck out the majority of the sterilization liquid. If the seeds are light they float, and then you pour the top layer into a new sterile bottle. Add 25 ml of sterile water and repeat 3 times. 10 | P a g e
B4. Remove most of the sterile water and shake the seeds with the remaining water, and transfer
a small amount of liquid (5 droplets to 1 ml) to a flask with nutrient medium.
Remarks:
The sterilized seeds must be sown immediately.
Remember that some orchid seeds are light, some are dark. There are usually some unimportant
sterile tissues from the capsule floating at the top. To see the actual seeds, you look into the
liquid after mixing. It is important to ascertain if they sediment or float upwards. In the rare case
they do neither (same density as water) you need to start all over and change the density of the
sterile water by adding some sugar before boiling.
Incubation
Some seeds germinate after a few days, some germinate after many months. Keep the bottles in
the light shade outdoors if you live in the tropics, or in a ventilated room with light ramps and a
temperature set for the species (default is 25°C). The ventilation may be needed to lower the
temperature in the room.
