I agree about the Molineux rose being pretty resistant to BS.Its a really good performer in my garden.

I can't speak to which DA's might be resistant in your zone and climate, but for what it's worth, the following have had decent BS resistance in my garden in Ontario, Canada and my Mom's garden in PEI, Canada. Some of these might be afflicted a little by BS in a non-spray and organic gardening environment here, but typically not very severe.

Gentle Hermione
Molineux
Crocus Rose
The Mayflower
Teasing Georgia
Tamora
Munstead Wood
Wild Edric
Mrs. Doreen Pike
The Ingenious Mr. Fairchild
Constance Spry
Geoff Hamilton
Harlow Carr
Queen of Sweden

These ones will get some BS or late season mildew here, but typically not very severe.

LOL. Body bagged roses are truly "grab bags" these days. It's now my conclusion that you never know what you're gonna get, EXCEPT that it's NOT going to be the rose pictured and named on the label.

Just for kicks (and because [a] hope springs eternal, and [b] because I'm a glutton for punishment], each year I buy a bagged 'Oldtimer' from either WalMart or Lowe's. This year when I unbagged my Lowe's purchase I found a metal tag that read 'Pink Double Knock Out'. The tag wasn't wired to a cane, it was simply loose within the bag.

Very curious, I potted the thing, waited, and watched as the heavily waxed canes turned first to a rich mahogany red/brown, then to a progressively darkening gray, culminating finally into terminal ebony.

I'm still grieving the possibility that I might actually have had the great good fortune to have copped a 'Pink Double Knock Out" for just cents over 3 bucks. Arghhh . . .

I bought 5 body bag roses at Walmart this past spring for $4.67 each. Although they have not been growing gangbusters, they are growing albeit slowly. They each have sent up at least one bloom so far and I found that all of them were properly labeled. What I found was that the root mass of these roses were about 1/3 the size of the rose canes. I guess you get what you pay for.

Has anyone noticed the Knock Outs being resistant to aphid damage?? I had aphids on other roses in my garden but none on my Double Knock Out, Pink Double Knock Out and Sunny Knock Out.
In that photo above-- it looks like rose slug damage.

Aphids & rose slugs love our Double Ko's here...

Yes, Mr. Lincoln, and you might look at Kirsten Poulsen. I believe it has the same upright habit that my Else Poulsen has. Don't know how tall you want the rose to be. In my small garden, I'm always encouraging upright growth, but Else needs no help, and there's never any sprawling. I'm sure there are many upright growers, but these are the two I am familiar with.

Altissimo is another nice, upright climber that is easy to keep in check and is healthy here.

I'll put a link below to the HelpMeFind listing:

In east TN, it's voles. That snake may have solved the problem, but there are millions of voles out there and the moles and subsequent voles love the soils in gardens and flower beds, far more than the compact soils of yards and hay fields. Snakes can only eat so many of them.

You may have done the exactly right thing, instinctively.

That rose is regrowing underground. IF we get hot and dry temps, you may want to reduce the lengths of the canes to lengths that the roots can support in dry weather. Even though you may be watering, July and August can be so hot that the roses become even more water needy and the roots haven't gotten back to their spring condition yet.

Have you had severe storms? Is it possible that with severely water logged soil and high winds the bush could have been uprooted? I know that I've had some problems with roses that toppled in the winds before. And it has been a very stormy spring.

I agree with Ann that you did the right thing by firming it back up right away. I would add that you might want to stake it temporarily to protect it from further upheaval. Just place a good sturdy garden stake in the ground near it and use some twine around the canes to secure it. With some time it should regrow the lost roots and the leaves will eventually replace themselves. Be patient with it and don't fertilize it until you see some good new growth. Keep it watered but be careful not to OVER water it. If it gets very hot there you might want to try and shade it somehow during the hottest part of the day too.

Those outer petals are called "guard petals" and they are supposed to look like that. They are very often misshapen and/or miscolored as compared to the rest of the rose, and they are there to guard the rose from the elements when it is still in the process of forming and then opening. When I cut roses to put in a vase, I take the guard petals off. Just rock the petal back and forth and it should just snap off for you.

Problem solved.

Florida, yes I am talking about the outer petals, no bug bite, I haven't seen any bug.
Scott we got cool spring this season but not wet. This season the stems and leaves are so beautiful but the flowers are same like before.

Kstrong, I am a new gardener and do not know much about flowers. It is nice to know the "problem solved" :-)

Thank you all for sharing.

Fun thread you guys!! I rarely bring my flowers inside, partly due to the cats, but mostly because I prefer to enjoy them outside. Once in awhile I might bring in a few stems, or occasionally someone will get me a bouquet of roses,etc. Years ago, our cat Princess (now gone) would tend to knock the vases over just by smelling the roses. She would make a mess with water going all over the place. Her replacement, Lola, loves to eat rose blooms tho. I have pics of her laying on the dining room table eating a rose at Christmas time. She's such a weirdo. Last time I bought some florist roses to try and root them, I let her eat several of the blooms because I didn't really need them for the attempted rooting (didn't work anyway). Lola is such a little busy-body. She always has to be right there with you, "helping" in any way she can. I just find it amusing.

I think if I were you, and wanted to bring the flowers inside to enjoy, why not make sure you bring one (or two) roses in that maybe aren't the most beautiful ones, and give 'em to the kitties to enjoy also. Maybe that will keep them from messing with your bouquet.

I could never be without at least one or two cats (we currently have 4). I've used the squirt bottle in the past, but just never remember to get one out. They don't really get into too much trouble to warrant getting it out I guess. But no matter how much trouble they might get into, nothing is worth traumatizing them by shoving them in a drawer for punishment! That's just not acceptable. Altho, come to think of it, one of them just might actually enjoy that!

Unmentioned above is the simple solution of getting a kitten. The kitten will make the mature cat's life so miserable that the mature cat will forget about the roses.

By the time the kitten is two, the mature cat will have chilled out. (Or taught the kitten how to do the attention getting rose reach)

Thanks for the feedback. Can't wait to get it planted.

We planted it, when it first came out, because of the claims of disease-resistance. What we failed to realize at the time was -- that was BLACKSPOT resistance!

We rarely see blackspot.
We see mildew and rust.

'Baby Love' mildewed badly enough here to have the appearance of a plant with yellow blooms and white leaves.

Gone.

Mowing will work fine on the lawn side. You can buy plastic root barrier 16" deep to set on the unmowed side. Roots that produce suckers probably don't grow that deep.

If you are ordering grafted roses, you can set the bottom of the graft right at soil level and this will prevent suckering. Canadian producers such as Hortico, Palatine, and Pickering produce grafted bare-root roses which are a good value for US consumers.

Normally most of us recommend burying the graft just slightly for zone 6 gardens, but not for winter-hardy roses that sucker.

What spacing do people suggest for a hedge of Dagmar? Three feet?

In my experience, Frau Dagmar root suckers with the best of the Rugosa's. To give you an idea, I planted a couple of them to frame the opposite corners of the bottom edge of a kidney shaped flower bed in my Mom's garden. They stay a nice compact 4ft tall, but have suckered so extensively in the last 5-6 years that they are basically about 10-12 by 8-10 ft now in terms of length and width.

That was from a single plant in each corner... I've offered to remove some of the suckered plants, but Mom likes them like this as they fill in the area nicely, so we've let them sucker unchecked and they are a sight to behold in full bloom.

I'm not sure a root barrier like plastic edging would stop it. You'd need to go deeper than 6" down and would need something stronger.

If two canes are affected, you should take the whole plant immediately. If only one, and you found it very early, you can try removing it at the graft or crown. This usually does not work, but it's worth trying for a mature rose or one that would be hard to replace. A more radical approach is to dig the whole plant and then split the crown, saving a cane or two and associated roots on the opposite side from the RRD cane. Then replant the hopeful part as a bare-root. This doesn't work with own-roots that have formed a taproot nor with grafted roses that haven't gone own-root. The rose needs to have a crown wide enough to split. Use a hatchet driven with a sledge or maul.

If the RRD rose was touching another rose, prune that side of the neighbor rose severely. I have definitely seen contagion by crawling to neighbor plants.

Very sorry you have an RRD rose, but I'm glad to hear from you, redsox. How is the garden otherwise?

Howdy, Michael! I think we will go ahead and remove the whole rose. I am suspicious of a neighbor too, and it is one that I believe you have as well: Mother of Pearl. Not that I have seen any strange growth, just that the spring flush seemed disappointing.

I am proud of my garden for the most part, although it grows despite a bit of benign neglect as I am part of the sandwich generation. My orchids suffer too.

Hope all is well with you!

Tebuconazole (Bayer) ... propiconazole (Banner Maxx) ... everything else that's said is just hysterics, IMHO. They're among the most inoffensive chemicals around. The stuff is even used in shampoos to prevent dandruff - Nizoral (ketaconazole).

Bayer advanced is very effective. Picture has nothing to do with anything. I just like to show off.

Sometimes you just get a dud plant. I've seen this in a few beds where I've done mutiple plantings of the same rose. Same bed, same light conditions, same soil and treatment and they just refuse to flourish even though the other 4 or 5 of the same variety do just fine. It happens.

In my experience, if it's a long-term problem, there's something in that hole that you missed - a rock, etc., that's blocking the roots.

If it's something else, then what others have recommended may work. Be sure it gets at least 6 hrs of sunlight. Build up a 3-4 ft diameter drip ring with mulch (I like shredded pine bark mulch), and feed it organics - my organic of choice is Mills Magic Mix.

If none of that works, there's something in that hole.

Thanks for the recommendations.

I get conflicting information on Fru Dagmar. A local nursery and some websites say it just flowers once, in the spring. Other websites say it flowers throughout the summer. What is your experience with this?

Frau Dagmar flowers very heavily in spring, but also repeats well all season and very well if dead headed. If not, she also sets beautiful red and large hips that add fall and winter interest. She's a beautiful rose and one of my favorite Rugosas.
