Jeanette Benson (503) 649-4118
Next meeting Tuesday, March 13th, 2007 @ 7:30 p.m.

Please bring the tubers you plan to donate to our annual fundraisers to the March meeting. Please be sure each tuber is
clean, free of rot and has a viable eye. You do not need to write on each tuber, as long as it is clearly marked in some way.
More than one tuber of a variety may be put in a bag with the name written on the outside of the bag. In preparation for
our annual sales, two workshops will be held at Swan Island Dahlias. The first will be on Saturday, March 31st, and the
second on Saturday, April 28th. The second one will be to prepare tubers for the Master Gardener’s Sale. Starting time
for both workshops is 9:00 AM. Please help out at one or both if you can. We need your tubers and assistance.

If you have tubers of newer varieties that are ready to be auctioned, bring them in and they will be auctioned off at this
meeting. The Board feels that we may get a better price if we do some selling prior to our main event and some of those
who take cuttings would like to get them sooner. This will be limited to newer varieties, or those that are very hard to find.

Doneen Burgess and Larry Smith will be providing cookies for the March meeting.

Ted Kennedy and Mike Riordan will demonstrate how they take cuttings with or without the use of a greenhouse. Bill
Mishler and Phil Mingus will discuss how they start and care for their first year seedlings.


We hope to have the 2007 Issue of Dahlias of Today available at the March meeting. This publication of the Puget Sound
Dahlia Association is a “must have” for all serious dahlia growers. It contains reviews of new varieties in the US and UK
along with numerous color photographs. You will want to read it cover to cover. See Doneen at the Publications Table to
purchase your copy.

If you haven’t already paid, dues are past due. Judges please remember that you are required to carry membership in both
the American Dahlia society and the PNDC (Pacific Northwest Dahlia conference). PDS dues, ADS dues and PNDC
dues should be combined and paid to the Treasurer as noted below. Federation of Northwest Dahlia Growers dues are
$10 and also payable through our Treasurer.

How are those tubers doing in storage? Regardless of your storage medium and method, it is advisable to see how things
are storing. Sometimes rot or insects can spread from one tuber to the next. Many growers believe that a rotting tuber
gives of ethylene gas which promotes premature sprouting in the other tubers in the same bag. While checking the tubers
you may want to select some varieties for cuttings. I don’t have the space to take all the cuttings I want at once. Therefore,
some tubers are rotated back into storage and others come out to take still more cuttings.

While going through your stored tubers please take time to set aside tubers for our Auction and Sales. We need everyone’
s support to insure the success of our annual fundraisers. Including a list of varieties and respective quantities is helpful to
the volunteers who will be doing the packaging at the workshops. Since the Portland Dahlia Society is a 501C-3 non-
profit, your tuber donations should be tax deductible. Their value would be what they went for at auction or were sold for
on the tables in the back.

March is a good time to get a soil test and find out what your ground lacks or perhaps has too much of a given element.
Cornell University requires at least a cup and a half of soil collected in a zip lock bag. It is advisable to take this sample
from several different places in your garden to get an accurate representative sample. Try to keep the sample as sterile as
possible by using very clean implements and wearing latex gloves. Ted Kennedy reports A&L Laboratories has recently
raised their fee to $33. Cornell University still charges $15, but their report is not as detailed. See Cornell’s link below: http:


Mark your calendars!!! The Pacific Northwest Dahlia Conference will hold their spring meeting at Steamer’s Restaurant,
8303 NE Sandy Blvd., Portand, OR 97220 on Saturday, April 21st The banquet facility is located on the upper level. The
business meeting starts at 11:00 AM. The luncheon will begin at noon. The bill of fare features Teriyaki Chicken and Roast
Pork Loin at $14.95 each with gratuity included. Please send your reservation and payment to Elva Sellens, 2651 Loma
Vista Dr., Roseburg, OR 97470.

This is a wonderful opportunity to meet and network with the top originators, growers and exhibitors in the PNW and
British Columbia. The most exciting part is the tuber and plant auction which begins at 1:00 PM. Many growers bring their
newest and best introductions and/or imports. The bidding is spirited and entertaining.
Membership in the PNDC is not required to attend any portion of this event. It is perfectly acceptable to arrive at 1:00 PM
and participate in the auction only, if this is your preference.

As I look back on my dahlia year just completed, there were some new developments of significance. One was the
introduction to, purchase and use of what I call long-handled scissors for dividing tubers. Check out Wayne Lobaugh’s
Dahlia Website at under “Catalog” which describes the Gardenman Pruners. That little
implement did wonders for speeding up the dividing of my dahlia clumps. I have known for some time that if I use a knife
for dividing dahlias, my progress slows considerably. Fortunately, the Gardenman Pruners kept me from needing to use a
knife for dividing dahlias for the first time in 15 seasons. They worked well for me in part because I like to divide my dahlia
hills 2-3 days after digging. For those who tend to let their clumps age and dry more, the scissors would become less
effective, since a more robust implement would be needed to cut through the drier fibers. This is also the first year I have
been able to get all my dahlias divided before leaving for my snow bird haven in the Sonoran Dessert. Incidentally, three of
our club members who have carpel-tunnel like symptoms found that the Gardenman Pruners bothered their wrists less
when dividing dahlia clumps than other implements they use.

Maybe I’m part of that 10% who don’t get the word, but finally, I was able to purchase and use the synthetic pyrethroid,
Bifenthrin, for control of some very destructive insect pests such as the cucumber beetle and earwigs, as well as aphids and
a number of other sucking insects. Bifenthrin is the technical ingredient in the registered products Talstar and Wisdom,
among others. One half ounce per gallon of water kept my dahlia blooms fairly insect free fro several days. With the
purchase of the best 2 gallon hand sprayer, I was able to deliver a fine mist that controlled the insect pests, yet didn’t seem
to damage the blooms. I alternated insecticide treatments by using Orthene as well as an early season application of
Malathion. In 2006, insect pests were kept at the lowest level my dahlia garden has experienced. I always wore a long
sleeve shirt when spraying and took a through shower immediately after.

When I first started growing dahlias, it was difficult for me to discard poor performing plants. Now my cultural practices
strongly emphasize desired traits and therefore, even more strongly discriminate against poor performers. In my current
mode, any symptoms of tuber rot call for plant elimination. A year ago, when digging out my hills, I discarded entire plants
if the mother tuber contained rot. This past fall, I repeated that approach and happily found only a rare rotted mother tuber.
Also, during the past two growing seasons, I have applied Eden Bioscience’s plant health regulator, Messenger, on a
monthly basis which may have helped lessen the occurrence of tuber rot. Hopefully, tuber rot, as well as other diseases will
continue to be held at a low level through use of the above practices.

New approaches? Certainly not for some, but they are…new to me.


We are all saddened to hear of Dick Canning’s passing on February 19th. . Dick had been a member of the Lane County
Dahlia Society in Eugene for many years, having been recruited into the dahlia hobby by Wayne and Eleanor Shantz. Dick
originated Nicolle C. and Kathy’s Choice, which won the Stanley Johnson Award. A photo of Kathy’s Choice submitted
by our own Jim Lawrence graces the cover of the 2004 Classification Book. I fondly recall Dick’s kindness in assisting me
with classifications the first few years I exhibited at the Eugene show. Our sincerest condolences to the Canning family.

Included in this mailing is a flyer for our sale and auction April 10th. If each of us could place (with permission) the flyer or
copies thereof in our area stores, community bulletin boards, health clubs, garden centers, places of employment or any
other place interested parties could take notice; this would help with the success of our sale. Click to got to
