JUNE 2001
COS NEWSLETTER
NEXT MEETING : Please take note of the date and time!
SATURDAY 23 JUNE 2001
starting at 15h00 at
Athenaeum, Newlands.
AGENDA
1) ORCHIDS FOR EVERYONE Compiled by Ann
Duckworth
This is a new programme form the South African Orchid Council listing. It deals with a
range of species and hybrids suitable for, as the title suggests, everyone. Ann has taken
care to describe natural habitats and cultural advice as well as allowing the audience to
enjoy the visual pleasure of orchids in bloom. Many of the slides are donations from
Carmen Coll who is a very accomplished orchid photographer so I’m sure we are in for a
treat.
2) PRIZE GIVING
The prizes from our Autumn Show will be awarded so please try to be there if you were
a winner.
Don’t forget the plant raffle and
plant sales at each meeting.
MEMBER NEWS
Happy birthday to everyone celebrating their special day this month. Delna Osborne
(12), Joan Hart (19) and Bess Gouws (21).
A warm welcome to new Members Mr. & Mrs. Burstein from Newlands who have relocated
from Natal.
Congratulations to Sarel and Madeleine Spies on the birth of their first child Luka who
was born on 4 May.
Lastly, we all look forward to seeing Brenda Vurgarellis strong and back to normal soon.
MAY MEETING
The plants that were brought elicited quite extensive discussion and interaction that
was beneficial to everyone. We heard a range of suggestions to combat mealie bug, scale,
and fungal infections which seems to be a common plague. Members issued a warning on the
use of Oleum, which appears to not be good for orchid plants and if used, may result in
deformed flowers. A dusting of cinnamon as a fungicide is effective, particularly on Paphiopedilums.
Remember that most insecticides and fungicides require a wetting agent (surfactant) for
effective management (you may want to try some grated sunlight soap). Phalaenopsis may
be susceptible to Aphidcide. Superthrive and Vitamin B1 is useful to promote root
production and a sprinkling of lime on Paphiopedilum concolor every 6 months
helps to encourage water absorption.
Thank you to Lambit Kaudla, Tricia Owen, David Ronaasen and Manfred Waltner who donated
plants for the raffle.
AUTUMN SHOW
Congratulations to all the prize and
ribbon winners. It was a wonderful Show with some new faces and helping hands that were
VERY welcome. Thank you to everyone who played their part up front, on the sidelines and
in the back room! Forgive me for singling out just one person, but there is a special word
of thanks to Virginia Schmidt who stepped in and organised the corsage table for us.

(Thanks to Umhlatuzana Orchid
Species Society)
SOME CULTURAL TIPS FOR JUNE
Don’t over-water as plants take longer to dry out during the cooler and shorter
days. Be careful of water collecting on Cattleya sheaths that could cause the
developing buds to rot.
Insert stakes for Cymbidiums that are coming into spike, but try to tie and stake
in the warmest part of the day to prevent snapping cold, rigid spikes.
Don’t change the plant’s orientation to light once the spikes have emerged, as the
different orientation causes crooked and twisted spikes.
Re-orientate the new growths on Cattleyas to take full advantage of available
light.
Vandas, Ascocendas and Oncidiums need to be given as much light as
possible, lift them above your other plants if necessary.
Nobile type Dendrobiums should be kept dry for the next few months.

LAST CHANCE
This is your last chance to list yourself in the 2001 Yearbook to sell orchids as a
non-commercial grower. If you regularly have plants to sell (not just the odd division or
two) but are not registered as a commercial grower, you may advertise in the listing to be
included in the Yearbook. This will cost you R100. Please contact me as soon as possible
if you are interested.
PLANT TABLE – There was no
plant table in May because of our "problem plant " programme.
NEXT MEETING
SATURDAY 23 JUNE 2001 starting at 15h00 at
Athenaeum, Newlands.
Please take note of the date and time!
