Campanula UK Z8

I fervently believed it was simply not possible to kill a rose in the UK so I was horrified to find Paul's Scarlet Climber (practically a weed) growing backwards and finally vanishing, leaving a smidgeon of dried stick. Less horrified (or just getting immunity) by the sad (but rapid) demise of Hot Chocolate. Finally, although Summer Song is not actually dead, it may as well be (and no doubt will be in a season or 2) as it is a 2 cane nuisance with a few puny blooms right at the very ends of long thorny whips. Oh yeah, the Renaissance roses - unfortunately immortal....but horrible - will deliver the coup de grace when I feel particularly peed off with Mr.Campanula or any of the ingrates (offspring) and I have a suitable weapon to hand..

I got mine from Steve Singer at Wisconsin Roses a few yrs ago. He doesn't list it on his website, but I bet if you emailed him he'd bud one for you. He has lots of roses that aren't on the website, and often does custom orders. But you have to catch him when he's doing the budding. It might be too late for this season, I don't know. He updates his list in October. Can't hurt to email him and ask.

Here is a link that might be useful: Wisconsin Roses

Thank you so much, Beth! I was already planning to ask him if he had a Pink Intuition available for next year! You are such a great help!

Here that would be Katydid. I've stood and watched one do that one early evening, after dark, with a flashlight in one of my hands and Felcos in the other. I wanted to see what was doing that. Then it got its head cut off.

Early evening, right after dark you can find them. They are easy to Felco.

Of course, your climate and pests are different...

He never tells us except to say that he guesses that the plant sucks the color out to recycle it again. What about pale pinks that bleach out? The rest is just wandering thoughts.

I always prune in the spring too,but the bottom of all the canes are completely bare and way too tall will it help or hurt to prune in the fall??????

I don't think it will help to prune in the fall. I prune in spring when the rose is most energetic, as I think this maximizes blooming.

Andrea, at the time in spring when you would hard prune an HT is the time to thin out small canes on most Austins to open up the bush. For young plants like yours just snap off the old blooms when they are done and you will have done all you need to do. And don't worry, after you prune out the old canes the bush will grow new canes and fill back in but look nicer during the first main flush. I normally only cut back the main canes by a third unless they are old ones.

In Zone 6 (at least in my region in Kansas) , it is best if you put the graft at soil level or a couple inches below. If it is at soil level, just provide some winter cover to help protect it. Apply the winter mulch after freezing weather arrives.

Of course if you have a winter like we had this past year, protection probably is not needed at all. Warmest winter I remember in this region.

Burying the graft 1-2 inches is the usual winter protection, but no, at this point I wouldn't dig up the whole plant in order to plant it deeper. Give it some winter protection and in the spring, when it blooms, see what you have. If Dr. Huey is all you have left, well, that tells you what to do, doesn't it!

Florida has the issue with nematodes attacking the roots. Can anyone explain how that manifests itself? Do the canes blacken from top down?

Good comments by Lyn.

Looking back, I need to say that my comment about drainage-not-a-problem was over-stated. I grew up on the Florida Ridge, and I tend to forget that so many people live in what used to be pine flat-woods, where the water table can rise to near the surface during the rainy season or after a hurricane, even when the topsoil is sandy. But the symptoms described by the OP don't sound like water-logging to me.

I, too, have heard that aphids get rid of thrips. My sad tale is that I used to have tons of aphids,but no thrips; I started spraying (my main hope was to get rid of beetles). It did nothing to the beetles, got rid of aphids , and now I'm pretty sure I have thrips (regular kind),since some "invisible bug" chews up the blooms so badly! So my new thing is : do NOT spray against insects! and hopefully Nature will balance things out again,and the aphids will come back...a sadder but wiser bart

Some thrips have a problem with high summer temps. Chilli thrips do not. I know they're still active because they're heavily damaging knockout roses that are used in the landscape around my neighborhood and town, and occasionally attacking other plants that I'm not spraying (papaya, hawthorne, hardy hibiscus, jasmine).

As for the actual products I'm using, I've used many - and haven't seen a huge variation in performance. The ultrarefined mineral oils (summer horticultural oil) are by far the least phytotoxic. In any case, I use them at night *after* the leaves have had a chance to cool down. As long as the leaf surface temperature is cool to the touch, and won't rise significantly in the next couple of hours, I don't see leaf damage. I've also used "Organocide". Finally, I've mixed plant oils directly with a surfactant (either soap or a non-ionic surfactant, sold as spreader-sticker). I've used canola, sesame, neem, karanja, mustard, as well as these oils infused with insecticidal spices/herbs. If there was any difference, I didn't see it. When used at less than ideal conditions, I did see light phytotoxicity when using plant oils.

I've used both Safer Insecticidal Soap (potassium salts of fatty acids) and Murphy Oil Soap (potassium salts of fatty acids, plus an amine oxide surfactant). Both work. Safer is slightly more expensive and easier on plants. When used in optimal conditions (low leaf surface temperature), I haven't seen any phytotoxicity from either product on roses. I have not tried using dish soap.

Hi Donald,

"Shrubblers?" Can you use such expressions on a public forum? Of course gardeners are a rugged lot, so are probably hardened to it.

I'll let you know which form of unmentionables we settle on.

I have Nahema and it is proving to be a bit of a miff in that the amount of dieback this winter was astonishing. It is also a very stiff rose which is not amenable to training. On the other hand, it has a wonderful fragrance and the silvery pink blooms are classically elegant, lasting well in a vase. Put it in your warmest spot (it really doesn't appreciate cold winds). Vancouver Island sounds as if it has a climate very comparable to England.

Absolutely.

I posted a picture of my Sharifa Asma's first spring flush a few months back. Big, beautiful, palm sized, amber and blush colored, intoxicatingly fragrant blooms.

The bloom that just opened on Sharifa today was a singlet, nearly white, and lacked fragrance.

The heat does awful things to roses...awful things.

Which is probably why here in the cooler zone 3 (close to the mountains), my roses' blooms can get huge! The colors are usually intense. So, I guess a shade net here would be a bad idea. :)

Could this be why my roses love fish emulsion?

Yes, fish emulsion also adds micronutrients. See:

Another reason is that on a day like today, at the end of the day the roses have all crisped in the heat when, in the morning, they looked great.

My house is full of roses three seasons. I take them to friends and family. Seems as though they last longer when I cut them in the evening. It may be due to michaelg's sugar. Thanks, everyone.

This is a pic in 2008 planted in 2003. Its 6-7 feet tall and 7-8 feet wide now. I thought it would be a small shrub. Grafted on multiflora from pickering.

As you can see I have allot perennials growing. Now that its at the larger size there is no room for other things to grow. Its on the left of this pic...It blooms nonstop all summer.I'm not a big fan of fragrance. It has a slight smell I think.

Hi Sue!
I have several DA's, all bought at local garden centers. You can check if there are any nurseries in your area that sell them (via DA's usa website). All of these were in 5 gal. pots, which really boosts your garden's maturity :) Also, this summer, I ordered a band size from Heirloom Roses. Which is nice, because they ship all year round.
In my garden, I have (from longest to newest):

-Windermere (petals shatter easily, but has a lovely myrrh/citrus smell)
-Abraham Darby (wonderful scent, very big/full blooms, good disease resistance in my zone 6)
-The Generous Gardner (really pretty, big blooms and nice fragrance)
-James Galway (smaller med. sized blooms, incredibly tight blooms that stay on for weeks)
-Charlotte (suffering from blackspot this year, slow to rebloom in this really wet weather)
-Munstead Wood (gorgeous dark red and old fashioned, quartered bloom, with phenomenal old rose fragrance)
-Crown Princess Margareta (just bought, no blooms yet, but it has taken off in its little band pot).

Just a note, from my experience DA roses tend to be rather bigger in US gardens (although, maybe MI will keep it a bit more restrained). So, just something to keep in mind when planning out their spaces in your garden :)

I am hoping Pickering roses in Canada will be allowed to send bare root david austins to US again next spring
Very inexpensive and I have over 50 that I have bought from hem over the years..Like about $15. Us each.
Us would not let them ship this past spring for some reason..
