IN REMEMBRANCE
OSA extends our sympathy to the
family of Marion Sheehan as we mourn the loss of
Marion who died from a heart attack.
Marion, a botanical illustrator,
and husband of 48 years, Tom, are both familiar to
us as the contributors of the “Orchid Genera
Illustrated” column in the AOS monthly magazine
Orchids. Also, Marion’s superb watercolors shine
forth in the significant 1994 hardcover book, (421
pages), “An Illustrated Survey of Orchid Genera” as
well as some 40 other books.
The AOS will soon be publishing
a definitive Encyclopedia of Cultivated Orchid
Species and Marion had been preparing 300 line
drawings to augment the 2000 color
photographs.
Besides her husband Tom, Marion
is survived by one son & daughter.
ANNUAL FIELD TRIP --- LAST
CALL
The August 6th monthly meeting
will be your last opportunity to register and pay
for our upcoming educational field trip. On
September 26th we will attend the Quail Gardens
Orchid Sale in San Diego. The sale is a fund raiser
for Quail Gardens and is the result of the efforts
of Greg Luetticke of Luetticke Orchids and Billy
Baker of Billy Baker’s Orchids. The San Diego
Orchid Society, the Palomar Orchid Society and the
Cymbidium Society will have booths at the sale. The
trip will include a stop at the San Diego Zoo for a
guided tour of orchid sites on the grounds and
their newly refurbished orchid house. The $115 per
member fee for this experience includes round trip
airfare from Phoenix, bus transportation to the
Gardens and addmission to the zoo. Upon arrival at
Quail Gardens each paid member will be reimbursed
$65 in cash to help with the shopping! Watch the
September newsletter for flight information,
departure time and meeting location. Please call
Keith Mead at 496-5762 to reserve your place for
what promises to be a great day.
MEMBERSHIP CARDS
1998 Orchid Society of Arizona
membership cards will be available to all paid
members at the August 6th meeting. Please see Keith
Mead for your card.
DEFLASKING AND POTTING UP
SEEDLINGS IS TOPIC FOR AUGUST MEETING ! ! !
Vic Polk, a long_time member of
OSA, has graciously donated a flask of Dendrobium
Joseph Teresi for our use. To that end, our August
program will be a demonstration on deflasking the
seedlings and potting them up.
As many of you know, deflasked
seedlings need a little extra care to insure they
establish their root system and grow properly. The
seedlings need higher humidity than can be afforded
growing exposed on your windowsill.
This does not mean you cannot
grow and nurture a seedling, it just means that
adjustments need to be made to insure their growth.
One example of insuring the
necessary humidity is available to the seedlings is
a simple little "greenhouse" which can be
constructed with very little trouble, and with
items you already have around your home. The
materials needed to construct this "greenhouse" is
a plastic milk jug (preferably a one_gallon milk
jug) which has been well cleaned, a clear plastic
bag, a handful of rocks or gravel (I use pumice
stone), and a small wire or plastic mesh to fit the
inside bottom of the jug. If you have these items,
you can prepare a WONDERFUL little greenhouse
environment for your little seedling to be very
happy in!
We will be demonstrating how to
make one of these "greenhouses", in addition to the
deflasking and potting of the seedlings. If you
would like to make a greenhouse to take home with
you, please bring your clean milk jug and hopefully
we'll have enough of the other materials to get you
set up.
I hope all who wanted one (or
more) of Bernice's plants was successful at the
July silent auction (and the live auction, too). Of
all of her plants, I was unsuccessful in getting
even one! However, the memories of the times I was
graced by having known Bernice will live in my
heart forever! Bernice was a special person, who
always gave of herself to help those of us new to
orchids, and to those of us who have grown orchids
for years who still found an occasional challenge.
She gave and gave and gave to OSA and our members
in every way she could, and she will greatly
missed, and always remembered. Enjoy and pamper
those wonderful plants that were once Bernice's,
and know she now takes great atisfaction in knowing
her plants are being cared for by her OSA
family!
I want to take just a little of
your time to thank those of you who brought plants
for Show and Tell. I also wish to apologize for not
allowing the time for us to be told about the
GORGEOUS orchids you brought for the display! I
think so many people were eagerly bidding on the
silent auction that it overtook the evening's
itinerary! I will try to rectify this problem. The
Show and Tell plants are very important to our
members _it not only gives us a chance to see
various orchids in bloom, but it gives us
encouragement to achieve the same results. I want
to encourage anyone to bring their plants for Show
and Tell. Again, I apologize for not getting around
to Show and Tell and hope to see all of those
beautiful blooming orchid displays at our future
meetings.
Stay cool _or at least try to
keep your orchids cool!
Lou Ann Remeikis
FROM THE PRESIDENT'S DESK
Wilella Stimmell
Our July 2 meeting was well
attended by members and guests who were apparently
more interested in bidding on plants donated by the
family of our late, beloved Secretary, Bernice
Ehrlich, than they were in July 4th holiday
festivities. Bernice would be pleased to know that
we raised many dollars from the sale of her plants.
We placed 130 plants on the silent auction, 2
special plants were reserved for a live auction
during the meeting, and 12 plants were placed on
the raffle table. Non-plant items, such as back
issues of ORCHIDS magazine and ORCHID DIGEST, were
also placed on the raffle table. Future raffles
will feature other such items donated by Bernice's
family. Other non-plant items will be sold at our
November 14 & 15 show and the remainder placed
in our Annual December Live Fund-raising Auction.
Silent auction sales on July 2
generated $797 for our treasury, and the live
auction of the two special plants, ably conducted
by Lou Remeikis, generated $100. It was unanimously
decided at OSA's June 28 board meeting, that the
proceeds from the live auction would be an
additional donation to the AFGC Scholarship Fund in
memory of Bernice. Our sincere thanks to the OSA
members who assembled at Bernice's greenhouse on
June 28, gathered up the plants, tended them, and
brought them to our meeting: Ann Cherny, Jane
Heckel, Kathleen Luther, Keith Mead, Lou Remeikis,
and Peggy Stejskal. Jane had the distinct pleasure
of entering Bernice's greenhouse at the very moment
the misters turned on and...she looked like a
drowned rat! One of Bernice's children had
apparently set the misters so that the maximum
amount of water would be dispersed. Though her
clothes were soaked and her hair was matted, Jane
laughed at her "good fortune" and never missed a
beat at gathering up the plants she agreed to tend.
Thanks is also due Leith
Plunkett and Natalie Warford. Leith hauled
non-plant items from Bernice's house to Natalie's
garage, and Natalie is storing the items. To date,
OSA has commandeered half of Natalie's garage! To
accommodate the new "load", we needed to remove the
many cartons of cotton batting we had saved from
previous plant shipments. Natalie contacted the
Episcopal Church Women of The Episcopal Parish of
St. Barnabas on the Desert, 6715 N. Mockingbird
Lane, Scottsdale, and the ECW Chairman, Mary
Heldenbrand, picked up ten 39-gallon bags which
were filled to capacity (and beyond) with the
cotton batting. The batting will be used to make
items for the ECW Christmas Bazaar. Thanks to
Natalie, the cotton batting was not wasted. The
handicrafters were pleased to receive our donation
and wrote us a letter of thanks. (ANY group that
could use the cotton batting we accumulate from
plant shipments, is welcome to have it.)
If any OSA member knows about a
group that would appreciate a donation of polyfill
for use in making handicrafts, feel free to let any
OSA board member know. The first name we receive
will get the next accumulation of "fluff". All we
require for our records - to account for what
happened to the cotton batting - is a simple note
of thanks from the group receiving our
donation.)
The July meeting was Suz
Cramer's last regular meeting with us. Many of you
already know that she is moving back to Telluride,
Co., at the end of July. She has had made several
trips north with her belongings, and in her absence
from Phoenix, Norma Kafer has been tending OSA's
plants in our greenhouse, which is still on Suz's
property. Norma has volunteered to become the new
caretaker of OSA's greenhouse, and in October, when
we hope the outside temperature is less
furnace-like, we will hold a greenhouse-raising
party to move the greenhouse to Norma's property.
We will present details on "the move" in the
September newsletter. Norma lives even closer to
the Valley Garden Center than Suz lived, so our
sale plants will be easier to haul to the
VGC.
Donations on our July raffle
table were received from: an anonymous non-member,
OSA, Anne Connor, the family of Bernice Ehrlich,
Julie Rathbun, and me. Thanks to all donors and to
members and visitors who purchased raffle
tickets.
MEMBERS ON THE MEND: I announced
at our July meeting that Vic Polk had broken a hip
and leg and was still hospitalized, that Phun
Krieger was going to have gall bladder surgery the
following week, and that Pam Albright and Lu
Robinson had had knee replacement surgery. You will
be pleased to know that Vic is home from the
hospital and mending, that Phun has gone back to
work following a brief convalescence, that Lu is
recovering, and that Pam Albright's new knees are
working well.
JIM JOHNSON attended our July
meeting, and we all gave him a round of applause in
grateful appreciation for his design of OSA'S NEW
WEB SITE! Jim said in an e-mail message, "What
started out as a simple web site, quickly turned
into a monster!" We appreciate Jim's expertise in
web site design, and we are very proud of our web
site! It contains comprehensive information
designed for orchid growers in the low desert, and
it also contains outstanding graphics and...music!
There are two addresses for our web site:
http://members.spree.com/jimni/orchids/osa.htm and
a shorter address, which will "fetch" the first
address: welcome.to/orchidsocietyaz One of the
Master Gardener's who checked out our web site,
stated: "Orchids in cyberspace - I love it!"
OSA LIBRARY ADDITION: Lou
Remeikis took charge of binding the ICONES
PLANTARUM: ORCHIDS OF COSTA RICA, authored by Dr.
John Atwood. The Orchid Identification Center
donated the work to OSA in grateful appreciation
for OSA's monetary donation to OIC. The funds were
used to purchase a badly needed herbarium scanner.
If any OSA member would like to check out the
ICONES from OSA's library, see Kathleen Luther, our
Librarian, at our meetings. When you see the size
of the ICONES, you will know that binding the work
was not an easy task. Thanks, Lou!
OSA T-SHIRTS: If you have not
yet purchased our "official" t-shirt, you will
surely want to do so before our field trip to San
Diego on September 26. Give me a call (947-8479)
before our August or September meetings, tell me
the size you need, and whether you want the fully
colored shirt or the kit with paints or...both! I
will bring the shirt(s) to the meeting of your
choice. The cost to members of either shirt is
$15.00. Those of us who have "our" t-shirts, will
be wearing them on September 26!
BACK ISSUES of "The Arizona
Orchidist" available for the current year: If you
joined OSA in mid-year, you are welcome to request
back issues of our newsletter. If you cannot attend
regular meetings, we are amenable to sending the
back issues to you via post. Contact Keith Mead
(496-5762) who has been mailing our newslettersthis
year or Jane Heckel (839-6696), OSA
Secretary.
NEW VGC DIRECTOR: The ink was
not yet dry on the letter I wrote to Bill Carls,
the President of the VGC Executive Committee,
wherein I appointed Anne Connor to be our Director
on the VGC Board of Directors. At the July 2
meeting of the VGC Board, Anne was elected Junior
Trustee, which left the position of OSA Director,
vacant. NELDA CALDWELL has graciously accepted the
position as OSA's Director on the VGC Board of
Directors. Nelda is a Master Gardener and, like
Norma Kafer, 2nd VP of the VGC Executive Committee,
is concerned about the continued viability of the
Valley Garden Center. Both Nelda and Norma live in
the Encanto area.
OSA TO PARTICIPATE IN THE MASTER
GARDENERS' LOW DESERT CONFERENCE AT THE WIGWAM
RESORT: At the June 28th OSA Board Meeting, it was
unanimously decided that OSA should participate in
the Low Desert Conference at the Wigwam Resort,
Litchfield Park, on August 7th and 8th. For this
event, we will not mount a display. We will sell
books and blooming plants, as well as distribute
free culture information. Your OSA board also
decided that since our August 6 meeting is the day
before the start of the LDC, that we would purchase
ADDITIONAL PLANTS FOR SALE TO OUR MEMBERS AND
VISITORS AT OUR AUGUST MEETING.
Also at our August meeting: Look
for two special bare root divisions of Lc. Jungle
Elf 'Cheryl Isobe' AM/AOS. Deacon Bell sent the
divisions via his recent visitors to Santa Fe, for
our raffle table! His mounted plant was in need of
either being mounted onto a larger slab of cork or
being divided. Deacon chose to donate divisions of
the plant to us. At the time he made the divisions,
his plant was in bloom. The sepals and petals of
the flowers are yellow with light flecks of rose,
and the color of the lip is rose.
UPDATE ON THE AFGC SCHOLARSHIP
FUND IN MEMORY OF BERNICE EHRLICH: 18 individuals
and OSA donated $1000.00 to the AFGC Scholarship
Fund in memory of Bernice Ehrlich. All donations
have been turned over to the AFGC Treasurer, Amy
Emary. AFGC usually awards $750 per scholarship
student per semester. We have written a letter to
Amy in which we stated that the full $750 should be
paid out to a scholarship candidate of our choice,
for the 1998/1999 fall semester. The remaining $250
will remain on deposit drawing interest in the AFGC
Scholarship Fund until the 1999 spring semester, at
which time OSA will add the additional $500
necessary to award a scholarship for the spring
semester.
OSA has also awarded Kristin
Huisinga, our scholarship candidate for 1997/1998,
a $500 scholarship for the 1998 fall semester
(Kristin's final semester of graduate work at
Northern Arizona University). We are pleased to
share our excellent financial health with the youth
of Arizona, and every OSA member can take pride in
the fact that we value education. Of the AFGC
candidates eligible for AFGC scholarships, we
select the student whose field of study most
closely matches our interests, whose need for funds
is documented, and whose grade point average
exceeds 3.0.
NEW PUBLICATION AVAILABLE FOR
VIEWING AT OUR AUGUST MEETING: Jack Kramer, a
prolific horticultural author, has grown orchids
for over thirty-five years. He wrote his first book
on growing orchids at home, in 1965. Some of you
probably own culture books written by Mr. Kramer.
The subject of his latest orchid tome is: BOTANICAL
ORCHIDS AND HOW TO GROW THEM. There are color
photographs (many are courtesy of Trudi Marsh) and
illustrations together with descriptions and
cultural information on how to grow over 350
different species (as opposed to hybrids) orchids.
This is a user-friendly book that minimizes
taxonomy in favor of practical information for the
successful cultivation in the home or greenhouse of
species orchids.
In "Appendix 2", page 191, Mr.
Kramer states that he has utilized the
classification system of orchids devised by Dr.
Robert A. Dressler because many orchid scientists
consider the Dressler system as the "correct" one.
(Dr. Dressler will be our speaker at our November
5th meeting.)
CULTURE CORNER: Those who
purchased plants of Brassia Edvah Loo at our June
4th monthly meeting might be interested to know
more about the culture of this magnificent brassia.
The following information was posted on the
Question and Answer page of OSA's web site:
Brs. Edvah Loo is a primary
hybrid of two species: Brassia longissima and
Brassia gireoudiana.
"Brassias, with their exotic
fragrances and striking flowers that resemble
spiders, are native to Mexico, Costa Rica,
Guatemala, Brazil, and Peru. Brs. species and
hybrids thrive in intermediate to warm climates and
are good choices for the low desert. Ample air
circulation and humidity of a minimum of 40% around
the plant, will help ensure success in maintaining
your plant's health. A number of orchids are
sensitive to location, including brassias. In
general, they can be grown with cattleyas or a
mixed collection of intermediate to warm
growers.
While the plant is in active
growth, continue to provide ample,
weakly-fertilized water. Cut back on watering after
the new growths have matured (possibly by late
Fall), but do not let the medium dry out
completely. This will stimulate the plant to
initiate the flowering sequence. After new flower
spikes appear, resume liberal watering.
If the roots of the new growth
would have no room to grow inside the pot, then
after the plant is finished blooming, it can be
repotted. Veteran orchid growers subscribe to the
philosophy that every time an orchid is repotted,
it is 'set back' (bloom time may be delayed or
absent altogether in a growth cycle, and the vigor
of the plant itself may take some time to recover).
Brassias, like a number of other orchids, do not
'like' to have their roots disturbed, so only repot
it when you think it is absolutely necessary (that
is, if the medium has decomposed and/or there is no
room for the roots of the new growth in the
pot)."
For historical perspective on
Brassia gireoudiana cultivation, one of the species
used in the Brs. Edvah Loo hybrid, growers might
find interesting the comments by George H. Pring
noted in the AOS BULLETIN, June,1939, page 6: "My
first collections of this species were made in the
province of Chiriqui, near the Costa Rican border,
in 1927. The finest plants were found at the time
of flowering in February, along the banks of the
river Caldera. They seem to prefer the small trees,
which overhang the river or line the gulleys
leading to it. Their favorite spot is on moss
covered branches; the various-sized plants from
seedling to mature specimens, attaching themselves
by preference to the extended branches rather than
along the trunk. In their chosen location they
obtain a generous amount of sunlight in the early
morning and late afternoon.
The genus is of no commercial
importance... They adapt themselves readily to
cultivation. ..."
Mr. Pring also notes that the
genus Brassia is named in honor of William Brass,
an early orchid collector.
While gireoudiana prefers higher
elevations (3000-4000 feet), the other species used
in the hybrid Brs. Edvah Loo is longissima, which
grows at sea level.
Do Orchids take in food only
through their Roots???
[ed note - the following
article, on foliar feeding was extracted from The
Arizona Orchidist Newsletter, Feb ’71, which took
it from the Orchid Digest, Jan-Feb ’71, “Orchid
Leaves, by Yeoh Bok Choon, which took it from the
Orchid Society of Southwest Asia Bulletin, July
’70.]
A - Many view the idea of foliar
feeding, [apply fertilizer, e.g. spray, onto leaves
of a plant - ed], with great scepticism and frank
disbelief. But the use of radio-active isotopes of
Potassium and the tracking of their migration from
leaves to stem to roots and back again, have proved
beyond doubt that foliar absorption is a fact and
not a wild theory.
Foliar absorption is also much
more efficient than root absorption. It has been
estimated that if chemicals are fed to the roots,
10 percent is absorbed and 90 percent is wasted or
held in the soil. In foliar feeding, 90 percent is
absorbed and only 10 percent is wasted. The
efficiency of foliar absorption is very clear. The
orchid has not suddenly changed its habits but has
been doing this ever since the beginning of plant
life; only, until now, we had not the means to
discover the process.
The top of the orchid leaf is
thicker than the bottom side and is covered with a
slightly waxy layer. This allows water to run off
the upper layer of the leaf more easily and
displeases the foliar feeder who would like the
chemicals to stay longer on the top of the leaf.
Adding a wetting agent or a detergent to the
chemicals is thus done to help overcome the wax
barrier.
The underside of the orchid
leaf, being the thinner and lacking the waxy layer,
absorbs water and chemicals much more quickly than
the upper. So that is where one should spray the
chemicals for foliar feeding, [ed note - as well as
for pesky bugs hiding underneath!!].
[ed note - Is the aforementioned
information out-of-date and now incorrect? No!! The
following information, section B, C; D, shows
paraphrased excerpts from various publications
during the 80's and on thru 1994, which further
substantiate the fertilizing technique as
legitimate.]
B - The following paraphrased
excerpts were compiled by Robert M. Hamilton,
Richmond, B.C.,Canada, and published in 1988, in
the THE NEW ORCHID DOCTOR, page 34,35.
"...experiments show that 90% of
the total potential absorption capable into an
orchid leaf occurs within 30 seconds if the leaf is
moist." Orchid Advocate, page 80, 1980. "cattleya
leaf intake can be vividly demonstrated with
radioactive phosphate moving into the leaf, then to
the pseudobulb." AOS BULLETIN, 1985, page
974.
"controversy exists: one group
believes it works, another doubts it and both are
right to a degree because the run- off to the roots
is half an hour after application on large plants,
so the assumption is that other elements can be
absorbed by the same pathway. Also, algae can be a
build-up problem on the leaves in foliar feeding."
THE FLORIDA ORCHIDIST, 1983, p. 11.
More proof: experiments showed
that a cattleya hybrid absorbed a trace chemical
through the leaves which suggests other nutrients
will also be absorbed; mid morning is the best time
to apply." AUSTRALIAN ORCHID REVIEW, 1982, page
107; AOS BULLETIN 1984, p.210 and 1986, p.
719.
More proof: cattleya leaves and
roots absorbed derivatives from phosphoric acid;
absorption thru the leaves was transmitted to the
pseudobulbs within 24 hours." ORCHID BIOLOGY, Vol.
II, 1982, p. 209.
Other plants: "'Liquid Sunshine'
formula = as used by rhododendron growers: 1 pint
corn syrup (Dextrose), 1 pint hot water, 2 oz.
seaweed liquid concentrated fertilizer, plus trace
elements; mix well; use 4 teaspoons; has been used
successfully on seedlings; fish emulsion may be
substituted for the seaweed product." THE ORCHID
ADVOCATE, 1982 , p. 73; 1983, p. 147.
Special mixes: "sugar sprays -
these caused cymbidiums to bloom earlier with a
stronger solution: 1 pint Karo corn syrup, 4 oz.
fish emulsion or seaweed+fish fertilizer, 1
teaspoon boric (borassic) acid, 12 oz. water; mix
well, use 4 teaspoons as a booster starting in
June." THE ORCHID ADVOCATE, 1984, p. 85.
"sugars = use a mist sprayer to
apply a solution containing 1 teaspoon of regular
fertilizer plus two teaspoons of sugar at time of
spiking; dilute molasses can also be used." THE
ORCHID ADVOCATE, 1982, p. 73.
"who uses it? = at Kew it is
mostly used in preference to fertilizing in the
pots." ORCHID REVIEW, 1987, p. 7.
C - From "Fertilizers and
Feeding of Orchids", by T.J. Sheehan, Department of
Environmental Horticulture, University of Florida,
in PROCEEDINGS OF THE 13TH WORLD ORCHID CONFERENCE,
1990, New Zealand, p. 124:
"Can fertilizer be given
effectively to orchids by applying to the foliage?
There are two schools of thought here. Some people
feel that it is effective because the runoff from
the spray goes into the medium and is absorbed by
the roots. Other people say it is an effective way
to fertilize orchid plants because the leaves take
up the nutrients. Actually, both are right because
fertilizer can be taken up by the leaves and by the
roots. Foliar application is a very affective [sic]
means of applying nutrients. Studies in our
laboratory using radioactive phosphorous on
Cattleya trimos plants showed that if radioactive
phosphorous was applied to a leaf, in 24 hours, 50%
of the phosphorous applied could be recovered in
the pseudobulb below the leaf where it was applied.
Hence, it is obvious that foliar application of
nutrients works.
Caution: When foliar
applications are applied, the leaves should be
rinsed with clear water the next day. This removes
the excess nutrients and rinses them down into the
medium. If you do not remove the excess nutrients,
algae will grow on the leaves, reducing the amount
of light reaching the leaf surface and eventually
weakening the plant.
There is no hard fast rule to
use as to when and how often fertilization should
take place. There are a number of factors that
effect [sic] fertilizer use by the plants, such as
water amount and growing temperatures."
D - From ORCHID BIOLOGY, REVIEWS
AND PERSPECTIVES, VI, edited by Joseph Arditti,
New York: John Wiley & Sons, 1994, page
383:
"Foliar application of
fertilizer is a common practice in ASEAN [sic]
orchid farms. Its effectiveness has been confirmed
with radioisotopes...It has been suggested that
better results could be obtained if foliar
application were carried out at night when stomata
of Crassulacean Acid Metabolism (CAM) orchids are
open... However, the advantages offered by open
stomata should be balanced against the
impracticality of asking workers to perform late
evening and/or nocturnal fertilizer applications.
Further, stomata are only one of the suggested
routes for the entry of nutrients into plants
during foliar feeding... For practical purposes,
local farmers spray all leaves, particularly the
under surfaces, to the point of a slight run off
and also a directed spray to the root
zone..."
