Thanks guys. I was curious but not concerned. It's only the one stem. My other bushes are grand.

I looked all over but couldn't find the bud munching culprit.

I agree absolutely, sawfly damage. The link below is to a site belonging to a fellow in Lincolnshire, UK. If you scroll down, you will find two species of sawfly which go by the common name of "Rose Sawfly". There is a third commonly called the "Curled Sawfly" here in North America. All three species are introduced species here, originating from Europe.

I had never seen these critters in Western Canada and I was as mystified as you when first saw them on my roses in Ontario. I have all three of the common rose sawfly's in my garden.

Control: If you check your roses frequently, every couple of days, it is fairly easy to pick them off. This spring, I had a pet robin who would follow me around and clean them up as I picked them, which made this little chore more pleasant for a few weeks. If they are not controlled however, they can completely defoliate a plant or even a rose bed. Knockdown spray, pyrethrin based, is also a good spot treatment if there are too many to pick.

Cheers, Rick

I order almost every yr from them. I am running out of room, but I lost quite a few roses this past season, so am looking to either replace or get something else. Their prices are the most reasonable, and shipping is also very reasonable. I plan to order CORETTA SCOTT KING, SUGAR MOON, and FIRED UP. Still debating if I want to replace two that died on me... BARBRA STREISAND and FIREFIGHTER (HACIENDA).

Regan's is a great source also, but even for me being here in the same state, the shipping is a LOT more. I do want to order JULIO IGLESIAS, as they are the only source for a grafted one. But to make that shipping cost worthwhile, I would prefer to add a couple more roses. Just not sure what I really want yet.

(Truth be told, I shouldn't be ordering anything at all!!) LOL

Nummykitchen- I'm in quite a different climate here in 10B/24, but I was at a nursery not too far from me recently that had a row of rather stunning Over the Moons. It was a truly wonderful Apricot hue in person. I frankly don't recall the scent, but boy it sure looked good and was quite floriferous. I hope it works out for you.

And my mother has told me that my grandfather always kept a Sterling Silver from the moment it came out. It always makes me smile to see.

Great info guys! Pickering Roses is actually close enough that I could drive there and pick them up. I will definitely look more into this.

Thanks!

Home Run is actually a Tom Carruth rose.
Home Run has knockout in its bloodline though...

Mzstitch, the carts here also say the same thing and I am in central Pennsylvania so don't think the nursery is quite local to me unfortunately.

And Kim, thank you for bringing this up, I have never even thought about why a grower would mislabel a plant besides laziness so this got me thinking. Appreciate the information.

You're welcome Karolina. Once you understand how some of these things work, you can make better informed choices and realize the gamble some of these "bargains" might actually be. Kim

Thanks all.

Kippy, I will try that.....Sounds like an economical alternative.

First of all, thanks to everybody for your insight...there's a lot of excellent information here already.

Some of the leaves have the necrotic spots described here and in some cases it has produced tiny holes in them. In other instances, irregular sections of the leaves have died and turn brown, particularly on the ends. At first I thought it was heat or fertilizer burn but it would only appear on a leaf here or there. I noticed the burnt-looking parts had discrete, fuzzy black undersides. Then, of course, the spots showed up. That's why I wondered if I'm dealing with both, but if they're hard to differentiate at certain phases...that's good to know.

Given what's been suggested here I guess I'll just deal with it. Some of my HTs have defoliated low down but look fine up top, and some of the leaves that are only marginally infected seem to not be getting any worse.

Ians, Michael, and Paul, thanks again. I don't know why the other photos didn't work but I'll try to fix it when I get home.

Leaf areas that are killed by fertilizer burn or whatever may be colonized by botrytis fungus, which could produce the fuzzy underside you describe. I would not be concerned about it. The pictured leaf with brown spots along the margin could have suffered fertilizer burn. That same leaf may have cercospora spots that are coalescing into a mass.

If ashy-looking centers drop out of spots leaving a purple-ringed shothole, that is anthracnose. You can have both diseases on the same plant.

I agree it is probably OK not to do anything.

"Paul, you need to give '27-07-16' to RVR to release as well....PLEASE!!!! "

I don't know where this plant is anymore - it may have been discarded already. IIRC it was a floppy shrub with an unattractive growth habit. I seem to remember it being stingy with repeat as well.

Paul, thanks for the info!!! I love the rose for its color and unbelievable texture...it almost looks fuzzy, or like velvet. I like what you bring to the table with your roses. It's hard to put my finger on it, and I just realized that's the essential draw they have. "There's just something about it..."

Modern roses keep coming out with more unique colors, more perfect form, better resistance, etc...but somehow many of them still end up feeling generic. I like roses with personality, that generate a feeling or response...especially if it's mysterious.

Anyway...floppy roses with unattractive growth habits and stingy repeat never stopped D.A..... hehe >;^)

Royal William is on my list to by for next year if I can find it. It's a beautiful rose. Thanks for the picture. It's a beauty.

Thanks Jim and Tuggy. It's listed as available at Pickering and Palatine. Palatine lists it as Duftzauber '84. In 2013 it was available from Heirloom, Northland and Rogue Valley that I know of.

I'm in warm, coast influenced CA but the only one that stands out on your list would Pope John Paul II - long vase life, smell to impress, and a lovely shape to this large one (4-5 ft) with long stems and not a lot of thorns.
Another long in the vase HT is Veteran's Honor but it's not big on fragrance to my nose anyway.

Thanks Peachie! I ordered PJP II.

Hi Lyn, thank you for your lovely post. OK, now I have a confession to make - that's not the rose that sunk. This (below) is the rose that sunk, poor devil. It looks somewhat less photogenic, though to be fair, this is not its finest hour.

Reassuring to hear that your roses thrived, though I would have expected no less. We too have well-draining soil, composed of equal parts of sand, big rocks, and small rocks. The mini-crater really does bother me, so I think I will add 2 inches of good dirt with some Sea Soil mixed in, then add a couple of inches of bark mulch to protect from the coming winter rains.

Thank you very much for taking the time to help me, very good of you.

Pauline

Hi seil, thank you for your response. I'm getting the message that these lovely plants are pretty tough, and determined to live. Except for the odd one I've killed.

Just took this picture of blooms on a Jacob's Robe climber, planted this spring. I'm hoping the rose will cover the arch with fragrant blooms.

Thanks again.

Blackgavotte and Canadianrose,

Here is an alternative method of propagating roses which may prove to have a much higher success rate than cutting. You need to do it quickly though before the rose becomes dormant. I would also suggest sealing the wound in the cane as soon as you cut the new root system off.

Best of luck

I missed my window for doing semi-ripe cuttings but will have a go at the old favourite, hardwood cuttings trenched in a nursery bed. I usually wait till leafdrop and winter dormancy, so end of October(ish). Nice quarter inch canes, with 2/3 incipient buds (around 8 inches long), stuck in a slit made with a spade. No cover, north side of house or garden. Can be done in a 5litre pot. Takes a whole year for a good root system to grow (no tugging or 'testing') so you would have a nice little plant, this time next year, ready to lift and transplant during dormancy. Not the most reliable (50% maybe), but certainly the easiest and least stress.

That's very interesting, Sidos. I wonder what others who have grown Eden would say--any similar kinds of situations or experiences?

Haven't decided yet what to do. Because Eden is so special, I'd like to re-plant her, but then I remember her less than wonderful traits (slow re-bloom and not very profuse, for instance), and then I start thinking of some lovely Austin climbers I wouldn't mind trying out . . .

Just don't know yet. For now, I'm just grateful for all the helpful input I'm getting here, as we try to figure out what happened.

Now that I think about it, my Eden can get pretty dry and stay happy. I've never had mine planted in a heavy/wet spot, but I can vouch that she may need less water than other roses.

If you have room, I hope you replace her (or yours may bounce back) :) Yours is so gorgeous!

I've tried various pruning techniques to try to get better bloom on my Eden. Mine had too many older canes, apparently. I pruned some so that she made new laterals, and those had good rebloom this summer! She may be one that likes what I call 'rejuvenation pruning'. My New Dawns like that, too.

It has to do with what they use for rootstock -- the different rules for Pickering and Palatine. Pickering imported theirs from Europe and Palatine grew their own. There were some (retaliatory) rule changes in the import/export regulations (that had zero to do with roses or rose politics or Pickering) and Pickering came out the loser, or so I've heard.

Thanks, Kath! :) You are so smart and on top of it in the rose world. Pity about Pickering taking such a bad hit. :(

I got them the year JC was put on the market--2007, I believe. You'll love how easy she is to grow. Diane

Thanks, Diane
