the addition of ‘Clair Matin’ to the Harding garden has proven to be one of my wife’s most recent (and endless) tales of “I told you so”. I had never even heard of this large flowered climber when she declared that its disease re-sistance and high aRs rating (an im-pressive 8.7) placed it at the top of her “must have” list. However, finding a

home and digging the hole for it was at the bottom of my to-do list, so it sat in a pot for months after its purchase. How was I to know that this 1962 Meilland introduction would completely trans-form a spot in our garden that I had been perfectly content to keep bare? starla was not so content and when I had procrastinated beyond her thresh-old of patience she performed her little “I’ll do it myself” routine and headed towards a neighboring fence with my shovel.

What a wonderful time we had at our society Picnic! Many thanks, from all of us, to Martha and lee Jeffery for opening their house and beautiful gardens to us. there was enough seat-ing to enjoy the day regardless of the weather. It didn’t rain but we took ad-vantage of the situation to spend some time indoors and escape the heat. the potluck items were many and deli-cious. there were door prizes. a good time was had by all.

speaking of rain, thank god, huh? I had been praying and wishing for rain since Mother’s Day. Here in Pegram, we received eight inches in four days. unfortunately, my wife and I had a two day trip to the lake planned dur-ing this time. needless to say, we were rained out. so much of life is a mixed blessing, but our landscape sure is happy.

sam Jones will have a report at our next gathering. It seems that the pow-ers that be lost all the stock cuttings for the next run of our beloved Cre-scendo rose. sam jumped into the fray and saved the day. I’ll let him give the details.

I’m proud to announce that Wendy Wise will be the guest speaker at the august meeting. Wendy maintains some of the most beautiful rose gar-dens in nashville. I’ve seen some of them and she really knows what she is doing. she’ll briefly discuss her spring regimen, and then move on to sum-mer maintenance. our summers with their heat, humidity and insects pose many challenges. Be prepared to ask questions that are specific to your ex-periences.

last but not least, august is Ice Cream social time. Bob Bowen brought his winning Custard Ice Cream to the picnic and threw down the gauntlet. It was delicious, as usual, and will be tough to beat. there is not much time left to experiment with different recipes. good luck to all the entrants. Contact Cindy Worch to coordinate re-freshments, please.

I’m looking forward to seeing every-one there.

Indifferent to my shrugs, starla “told me” that ‘Clair Matin’ can reach a height of 6’-7’. time has confirmed this state-ment to be true. I imagine before it is over with, the maximum known height of 12’ will be surpassed by our ‘Clair Matin’ so starla will be able to have “I told you so” tattooed on her forehead. Despite its thorns (and one big starla thorn in my side) I have gained an ap-preciation for this beautiful rose.

the 3-inch double blooms of fifteen petals are borne in clusters of three to seven blooms. Pretty coral colored buds open first with bright tangerine stamens and salmon petals that later fade to a lighter pale pink. this rose is both a prolific grower and bloomer all season long. even throughout the heat of summer, its dark green foliage is a beautiful back-drop for the endless clusters of medium pink blooms. While books describe ‘Clair Matin’ as having a moderate sweetbriar fragrance, I can-not deny its worthiness of a high rating even if there is only a mild fragrance in our rose.

Just as starla and I were leaving for the most recent nRs grand Prix, I snipped a cane from this rose. not only was ‘Clair Matin’ the only rose we entered that won an award, seemingly every member present that night waited until starla was within earshot to ask me what was the name of “that beautiful rose”. to my dismay “that rose’ continues to grow as vigorously as does the long list of “I

‘Clair Matin’

told you so’s” from my wife.

In the end, I have to admit my wife was right (ouch), ‘Clair Matin’ is a “must-have”. But if you don’t believe me, just ask her. she will be more than happy to tell you so too.

last month the main topic was H2o. august in Middle tennessee is more of the same. Yes, we did get a nice reprieve with some much needed rain, but the high temps still place a high priority on keeping our babies hydrated. the keys to success are pretty simple. use thick layers of mulch and water deep and thoroughly. the best part of august is the Japanese Beetles are gone!

I recently learned that high summer time temps are not just something to worry about as heat stress on you and your roses. When using herbicides on your lawn for weed control it is impor-tant to make sure to only apply them when the temperature is under 85 de-grees. above 85 degrees these chemi-cals can become volatile and evaporate creating a vapor cloud that can drift into your roses and other desirable plants with adverse effects.

While dealing with the summer heat a good way to get through august is to think about how what you do now will insure a beautiful flush of fall blooms in september! so what to do?

feed your bushes. august is an ideal time to add organic fertilizers, like cot-tonseed meal, alfalfa meal, mushroom compost, composted manure, fish meal, kelp meal, etc. or pre-packaged products like Mills Magic Rose Mix. the great thing about feeding with or-ganics is they release nitrogen slowly, so they won’t burn roots, and will be there for the fall blooms. organics are also good for the soil.

You can also incorporate some fish emulsion or liquid kelp with your fa-vorite liquid fertilizer of choice. If you are wondering, fish emulsion does have its own ‘fragrance’, but while the

August Rose Care (Cont’d from page 2)

By: Jim Harding

“Out of Sight, Out of Mind” is a well-known phrase that dates before the 13th century. This is one of those popular sayings that unfortunately increases in intensity with age. For the rose gardener anything that is out of sight has a greater likelihood of being out of mind and hence be-ing neglected. Nothing in your rose garden is more out of sight than pH.

Therefore, every rose garden needs a pH Policeman, to remind us to periodically check the pH. At our house, my wife is the pH Policeman, and when the roses begin to show signs of weakness, she will say to me, “Have you checked the pH late-ly?” If you are serious about grow-ing roses then invest in a good soil pH meter, and check the pH in your garden at several locations at least quarterly. For more information about pH and pH meters contact a

August Beginner’s Rose Tips

Consulting Rosarian.

Charles lott, Consulting Rosarian

Rain - Rain - Rain - what a bless-ing the Lord has given our drought-stricken rose gardens. But how many saved the water that down spouts carried? My tip for the month is to try “water harvesting”. Several arid states practice this op-eration currently. Not only is the water better - it is MUCH better than city water on crops. Not for drinking purposes, however. The pH factor of rain water is much better for rose bushes. Other fac-tors make it better, including more nutrients for fertilizing the plants.

During the Deep Depression, peo-ple practiced “water harvesting” regularly. Barrels and cisterns were the vehicles used for storage. Try it and your roses will love it.

smell doesn’t last, the benefits to your roses does!

Keep spraying regularly to keep dis-eases like blackspot under control. If blackspot gets out of control, you will need a fungicide that contains the ac-tive ingredient of mancozeb (manzate) that kills blackspot on contact. It may sound excessive, but remove all the dis-eased leaves and then spray three times every third day. You can then return to your regular spray program that likely uses preventative fungicides like Ban-ner Maxx (propiconazole) once every two weeks or ortho Rose Pride (trifo-rine) once a week.

try spraying for insects only if you see them or their damage. this time of year the biggest pest is the two-spotted spider mite. these little devils will de-foliate and can even kill a rose bush. a very hard water spray aimed at the un-derside of the leaves is a good method to knock them off. If you have a lot of

roses, it’s your choice as to how much time you want to spend. We have over 200 roses, so I use a miticide like avid, floramite, or shuttle. each of these miticides has a different mode of action to kill the mites, which is important to alternate, so you avoid having the mites building up a resistance to one particu-lar miticide.

Reminder, always mix fresh chemicals each time you spray; leftover chemicals won’t be effective. to avoid possible leaf burn you can either spray in the morn-ing; as long as the dew is gone; dew will dilute the spray and lose efficacy. or you can spray in the evening making sure to allow enough time for the spray to dry so the leaves do stay wet overnight.

Deadheading and pruning; yes, there is a difference. Deadheading is as simple as it sounds - removing dead flowers to encourage the next bloom cycle. some rosarians use the old rule of thumb and cut just above the first 5- leaflet set

above a bud eye. others just remove the bloom and wait for the rose to show where the new growth will come from and then cut back just above that new growth.

for an even better show of fall roses, cut your bushes by a third in mid to late august to maximize fall blooms. Cut-ting back will stimulate growth, pro-mote blooms on strong stems and help you to be ready for the nashville Rose show on october 7 at Belmont univer-sity. Big roses take longer to re-bloom, typically 45 days or longer. Miniature roses typically take less than 45 days to re-bloom. the more petals a rose has, the longer it takes to bloom.

even if you don’t plan on exhibiting your rose at the show you will at least be guaranteed of having plenty of beau-tiful roses to share with friends, fam-ily, neighbors and anyone you want to make a smile!

Google the Internet with a water harvesting inquiry - it will in-struct well.

ted Mills, Master Rosarian

During the hot summer weeks I think you can’t emphasize wa-tering enough. I water every other day when it is 90+ and not raining. When it is upper 90’s I’ll give the roses a bath with the car wash nozzle. This knocks down some spider mites too. Even with all my watering the roses suffer. After a week and six inches of rain the roses are coming to life like it’s spring. Just goes to show you that you can water a lot and it helps but there is no substitue for cooler temps and rain.

Rose Chat RadioBy: Jim Harding

Back in the february 2010 issue of the nashville Rose leaf, nRs member leann Barron wrote an article titled, “Roses for the next generation”. In this award of merit winning article she talk-ed about “hearing jovial grumblings in rose circles and poo-pooing about com-puters and technology, and noted it’s no fad, and we’d best get on the social me-dia bandwagon”.

fast forward two years and along comes Chris VanCleave, a.k.a. the Redneck Ro-sarian, a blogger and active member of the Birmingham Rose society. His pres-ence via facebook, followed by Rose Chat on twitter and now live broadcasts with Rose Chat Radio via Blog talk Ra-dio have hit the social media trifecta! But what does all this mean? Chris Van-Cleave is on the social media bandwag-on big time!

In addition to being a direct pipeline to the “next” generation of rose lovers, social media can also reach those of us who were not born with a smart phone on our hip. for folks who have been growing roses longer than some of us have been using computers, take heart. the ease of use of computers has come a long way so no need to sit on the side-lines and let gens X and Y have all the new fun to be found online at Rose Chat Radio.

so how big is big? along with his co-host, teresa Byington, their recent Rose Chat Radio broadcast that featured Paul Zimmerman talking about the Bilt-more International Rose trials reached 30,000 listeners! Considering the american Rose society has only around 10,000 members it makes you won-der who are these people? a quick side note: a big topic in the recent campaign for aRs Vice President focused on how to increase membership. In less than a year the fact that the size of the Rose Chat Radio audience has lapped the aRs is proof that people are still inter-ested in roses and consider this forum a real benefit. since both candidates were interviewed on Rose Chat Radio they are witness to the power of social media which will hopefully lead to the aRs leveraging this and other means to increase their outreach program to both current and future members.

getting back to Chris and teresa; what exactly is Rose Chat Radio? sim-ply put it is the only show dedicated to growing roses, with interesting guests and the latest news from the world of rose gardening. according to their website, “Whether you have one rose, a thousand or simply an interest in roses, you’ll love RoseChat Radio on BlogtalkRadio.”

so how does one get connected to lis-ten in on these broadcasts? simply go to RoseChatRadio.com and click on one of many broadcasts to pick from. You can listen on your computer, smart phone or download as a podcast to an MP3 player, like itunes, and listen at your leisure. and if you are interested you can listen live every saturday at 9:30 aM Cst where you can even call in and be part of the show. the first live broadcast I listened to happened to be Paul Zimmerman. as I listened to him talk about the only international rose trial that is being conducted on the east coast at a place that has been our wish list to see I wanted to know more so I called in via the toll free number. Chris answered, and there I was talking with Paul live on the air about how and when to see the Biltmore rose trials in action. Pretty cool. (see related article on page 5 for more details about the Biltmore rose trial)

to get more insight into how this all came to be I reached out to Chris. While he currently resides in Birming-ham, alabama, it turns out he is origi-nally from nashville and talked about his mother growing beautiful roses at her home in the Donelson area of nashville. Chris also shared the story behind his first rose. He was chatting with his elderly neighbor, Mrs. Dodd, about her roses and she mentioned the rose in his yard. He reminded her that he had no roses. she then cor-rected him that he had been mowing over his rose ever since he moved in.

The Biltmore Rose Trials

By: Paul Zimmerman

the Biltmore International Rose tri-als were started in 2011 as a way to test and showcase new varieties of roses from around the world. they are an environ-mentally friendly trial designed to be accessible to all rose breeders–from pro-fessional to amateur.

the trials take place in the main walled rose garden at the historic Biltmore in asheville, nC, originally designed by fredrick law olmstead. the garden now houses over 2000 roses comprised of over 250 varieties. the garden’s formal layout, its close proximity to Biltmore House and talented gardening staff make it an ideal setting for an Interna-tional Rose trial.

Based on the rules of other Internation-al Rose trials in europe, the Biltmore trials take place over a two year period. a new trial is started every year so at any given moment there are two trials run-ning consecutively. the roses are judged 8 times over the two year period by a per-manent jury made up of gardeners, gar-dening media and horticultural experts. the makeup of the permanent jury is designed to reflect a broad range of gar-dening interests – not just rose growers. Judging is done during peak bloom in spring, the dog days of summer, peak fall bloom and in winter just before pruning.

In May, at the end of each trial period, an International Jury will come to also do a round of judging and that is the day winners will be announced at an awards luncheon.

Winners are announced in several dif-

ferent categories. the first is by Class such as Hybrid tea, shrub, Climber, groundcover, floribunda and open Class, which are roses that do not fit in the five main classes. additionally, awards may be given for fragrance and disease resistance. the highest scor-ing rose of all wins the top award. the Biltmore International Rose trials also feature a guest Choice award. this award is selected by the public, who can text in their vote right from the garden throughout the two year trial period.

In an effort to make the trials acces-sible to all rose breeders, roses can be entered in sizes ranging from a one gallon own root to a full sized bareroot plant. each breeder is allowed to enter two varieties, six plants of each variety are needed and the rose cannot have been in commerce more than two years anywhere in the world.

Care for the roses is done using envi-ronmentally friendly products such as organics. Chemicals can be used, but only as a last resort. the goal is to care for the roses in the same manner as the back yard gardener.

some of the roses in the trials may find their way into the newly launched Biltmore garden Rose Collection and even make their way into national distribution for sale to gardeners. the collection is comprised of the best new garden roses from around the world. ground covers to climbers, shrubs to Hybrid teas and beyond; all the roses share in common good disease resistance and varying degrees of fra-grance.

Biltmore was built by george Vander-bilt at the turn of the last century and furnished with treasures from around the world. at one time the Biltmore nursery was one of the largest com-mercial plant nurseries in the united states. now, a century later, it is home to a trial for treasures from the Inter-national Rose World, some of which will continue the tradition of bringing beautiful plants to united states’ gar-deners.

after showing Chris where the rose was he began mowing around the spot and remarkably it grew into a beautiful red climber. a great example that roses can truly survive despite what we do to them!

since moving to Birmingham in 2000, Chris’ garden has reached the one hun-dred mark. What began as a garden journal on a spiral notebook become a blog and also a page on facebook as a means to promote roses from there, “the Redneck Rosarian began a month-ly chat on twitter. If you are like me and love roses but do not tweet, don’t fret. there is an easy to follow tutorial at www.rosechat.info . through the twit-ter rose chat the idea was hatched to create an online radio broadcast. fellow gardener and rosechat tweeter teresa Byington joined Chris to launch Rose Chat Radio. an interesting tidbit is that Chris, who lives in alabama and teresa, who lives in Indiana, have never actu-ally met in person. another, testament to the power of social media. In case you are wondering, the answer is yes, their spouses know.

all kidding aside the purpose of Rose Chat Radio is threefold:

1. teach people how to grow great roses

2. teach the educational value associat-ed with showing roses, and most of all

3. teach the importance of sharing ros-es

needless to say I am very excited about what Chris and teresa are doing to pro-mote the love of roses through social media and want to encourage everyone who reads this article to not only join in, but to also help spread the word. leann Barron ended her article noting that “savvy organizations recognize that generation X, Y and beyond aren’t going to come to them, they just aren’t seeking us out”. let this be a call to our local, re-gional and national organizations to get on board, because social media can be used in meaningful ways to add value to being a member. Rose chat radio is just the beginning and thank you Chris and teresa for leading the way!

there are a number of different pes-ticide types used by rose growers to regulate arthropod (insect and mite) pest populations including contact, stomach poison, systemic, and trans-laminar. translaminar pesticides (insecticides and miticides) are used against an assortment of rose pests including spider mites and thrips be-cause the active ingredient is distrib-uted into plant tissues where these arthropod pests feed. those pesti-cides with translaminar activity that are commercially available for use on roses include spinosad (Conserve), imidacloprid (Merit), acephate (orth-ene), abamectin (avid), spiromesifen (forbid), spirotetramat (Kontos), and etoxazole (tetrasan).

translaminar or “local systemic” activity refers to absorption by one-side of the leaf surface so that the ac-tive ingredient is available to insect and mite pests feeding on the other or untreated leaf surface. the active ingredient penetrates leaf tissues and forms a reservoir of active ingredient within the leaf that may persist for up to 14 days; however, this is dependent on the specific translaminar pesticide. a variety of factors may influence the activity of translaminar pesticides in-cluding leaf structure (surface), leaf age, and development stage of plant growth (in this case, rose). translami-nar pesticides may enter the plant leaf after application with penetration oc-curring primarily through the leaf cu-ticle. the mechanism involved in pen-etration and movement into leaves via the leaf cuticle is by diffusion, which is the movement of compounds from a

region of higher concentration to one with a lower concentration. However, the distance in which translaminar pesticides may diffuse across the leaf may be affected by the leaf cuticle.

the leaf cuticle functions as an effec-tive barrier, which inhibits absorption and transport of foliar applied pesti-cides into the leaf. the leaf cuticle is very lipophilic [an affinity for dis-solving in lipids (as fats)], which may impact penetration into the leaf. the permeability of the leaf cuticle is an important factor that may influence penetration and movement through leaf tissues and may vary depending on the presence of cuticular waxes on the leaf surface, which may indirectly impact regulation (control or suppres-sion) of arthropod pests when using translaminar pesticides.

leaf cuticle thickness may impede penetration by inhibiting the diffu-sion process and ability of translami-nar pesticides to enter the leaf and move into areas where arthropod pests are feeding. However, cuticle thickness may differ between the leaf top and bottom. any variations asso-ciated with penetration through the leaf cuticle may be due to differences in cuticular waxes and leaf cuticle thickness, which may be contingent based on the rose cultivar. also, envi-ronmental conditions (temperature, sunlight, and relative humidity) un-der which plants (roses) are exposed to may affect cuticle thickness or leaf rigidity. In fact, both ambient and leaf temperature may effect penetra-tion through the leaf cuticle and thus impact efficacy. for example, studies have shown that cool environmental conditions lead to reduced efficacy of translaminar pesticides compared to warmer temperatures. the proposed mechanism responsible for this differ-ence is that higher temperatures may change or alter cuticular waxes (long-chain alcohols, fatty acids, and hydro-carbons) thus increasing permeability and transport across the leaf cuticle.

Plant growth rate or age may impact the effectiveness of translaminar pesti-cides as applications to plants produc-ing vigorous leaf growth may result in greater mortality compared to plants not actively growing (e.g., flowering), which may be affiliated with increased leaf rigidity and/or a thicker cuticle (older or senescing leaves). this re-sponse may also be due to plant stress (e.g., lack of adequate moisture). In addition, the cuticle of new or young leaves is thinner and thus more per-meable than mature or older (thicker) leaf cuticles. However, in some cases, thicker cuticles are more permeable than thinner cuticles.

the activity of translaminar pesti-cides may be affected by surfactants, which enhance penetration through the cuticle and into leaf tissues by re-ducing surface tension of spray drop-lets on the leaf cuticle thus increasing the total surface area covered. Howev-er, this depends on the type of surfac-tant and concentration applied. Hor-ticultural and mineral oils have been reported to enhance the activity of certain translaminar pesticides (e.g., abamectin or avid) through improv-ing penetration through the cuticle layer and permitting compounds to remain in solution longer, which re-duces evaporation from leaf surfaces and allows more time for the pesticide to penetrate the leaf cuticle.

In summary, there are a number of factors that may influence the effec-tiveness of translaminar pesticides including timing of application and coverage. In addition, the activity of translaminar pesticides is affected by the leaf cuticle, which is associated with thickness and waxiness. this article was developed to assist rose growers in understanding those fac-tors that may be responsible for “inad-equate regulation” of arthropod pests of roses when using translaminar pes-ticides.

Lee Jeffery, center in white shirt braves the heat with show and tell time in the garden

When gordon and I left nashville heading for gallatin to the picnic, the temperature was hovering around 104°. We were prepared to swelter, but knew how great the picnics always are, so also felt that it was worth it. Wayne and Dottie Metcalf arrived as we got there at 5 and we all headed to the back yard. surprise! no tables, no people, what ?? We rang the doorbell and lee and Martha Jeffery ushered us into their blessedly cool and lovely home where everything was set up for an indoor picnic. Hooray! they had even set up tables in the garage and air-conditioned it. so we had a won-derful indoor picnic with a fun group of members as always.

fortunately, about the time we fin-ished eating, some clouds came up and cooled things off enough for us to enjoy seeing the garden. Why was it so green? they have a well in the cute wellhouse lee built. therefore the garden looked great and the roses were shown off to advantage against the white picket fence. luckily, the storm that came through their area recently and blew down nearby trees didn’t damage their yard.

Charles and ann lott made an ap-pearance and we were all glad to see ann up and about since her recent heart surgery. sam and nancy Jones brought a returning member, Rita Bullinger (formerly goforth), with them. Welcome back, Rita.

thank you, lee and Martha, for going to so much trouble for us. Your home and garden are lovely and I am sure I speak for everyone who came when I say that a good time was had by all.

The heat outside did not spoil the picnic fun inside. NRS President, Tom Beath, calls out the winning numbers
