Diane,I'm sorry to bother you again, but I have another question about the Mystery Damager. Looking around the other day, it seems to me that perhaps it's limited to mainly just one rose right now: The Ingenious Mr. Fairchild, an Austin. Now, I seem to remember that earlier this year, it may have occured with James Galway as well, another Austin,but JG was having other issues with flowers opening badlyand damaged, which may have been due to the weather,as well as the fact that it's between 2 ramblers, and I added in some other neighbours last fall, so maybe JG is having issues with that, as well. On The Ingenious Mr.F,the damage is mainly just in the center : the stamen area is completely blackened,and the stamens are gone; it's just this ugly black nub,spoiling the effect of the flower entirely. Does this description sound like what you are experiencing? thanks, bart

I've just got to get some photos of this damage for you to see. The worst of the damage seems to be winding down rapidly. Your description is quite similar to the damage on my roses. Buds are either "drilled" out in the very center, or eaten out more extensively. The stamen area is completely destroyed. The discoloration ranges from blackish brown to light brown. Even the edges of the outer bud petals are affected with brown discoloration. The severely affected can still try to open and the bud is mostly destroyed on those. Less severely affected will open, but the center is missing. I have several Evelyn roses which have been affected for years. Others which are susceptible are Colette (severe), Caramel Antique, The Prince, Augusta Luise (severe), and Love Song. These are all many petaled roses with an antique look. The puzzling thing is that these roses grow right next to other roses that aren't damaged at all. I also have thrips damage on some roses that aren't "drilled", just have the brown edges on some petals. None of these look as bad as the above photos show. The drilled buds have different look entirely. I'll try to get some up soon. Maybe we can solve this thing together. Diane

Thanks for the update on your rose bush... Very nice Dingo!

Great update and a beautiful rose!

I only see mild slug damage on your older foliage near the base of the plant and no recent damage to the newer growth. Thus I think your rose slug season has ended and you don't need to do anything at this time.

I agree with Cecily. Remember that after a week or two of activity, rose slugs disappear--because the good predator bugs arrive and eat them up. While the rose slugs are present (and you often have to squint to see the tiny green things on the backs and edges of leaves), squish them (or toss into your yard--they probably won't find their way back). Once good predator bugs arrive, do nothing--except maybe pluck off some of the more damaged leaves if they are looking particularly messy.

Depends. I've put large roses in i gallon pots, but I cut them back severely and also root pruned. They mist remain in a shady location and be monitored closely for drying out.

Question - do you mean thrive in permanently, or just for a little while?

I agree it needs a support to grow on, and I like your idea of planting it to grow on your fence. HMF says it is "climbing, spreading". Along with the comments above that it gets really large, I would think it would do well on your fence. Partial shade might cause it to not be so aggressive. Just make sure to tie the first long canes horizontally on the fence, and stand back.

Wow - this climber sounds almost scary. But I like a challenge!

summersrhythm_z6a are you sure that the lack of blooms is due to midge? The stated period of bloom for that garden is June 15-September 30. Rugosas normally bloom earlier than other types (in my experience).

Yes Henry, I saw the damage in every rose bed, the burnt tips everywhere. I will call them today to let them know.

Thanks Michaelg. I have new climbers this year too so I will heed your advice. Good to know.

Could some of u experts post pics of ur trained climbers .. That will help me train my young golden shower climber .

Sugar Moon?

Wimi has pink stamens.

Vasue, I was just going to post that. I have Pink Don Juan. HMF doesn't say it's a sport, but I would guess it is based on the way the bush looks and the blooms. The picture from Chamblees is not the right color. It is a deep hot pink. It also has a wonderful fragrance.

Chamblee's link above gives the history as "sport of Don Juan". Nelson's Roses lists their Catherine Nelson as a sport of Don Juan they discovered - first rose on the list - http://nelsonsfloridaroses.com/rose-varieties/pinks/.

Thanks Jasmine, I am wondering if it might work out for my north facing garden. They are not that common around these parts, but if the pictures online are any indication, it certainly looks like a rose worth searching for!

I thought it funny that my own root Night Owl was taller than my friend's budded one that she got around the same time. This rose could be rootstock.

I'd call them and see if they used to carry JACOB'S ROBE. With the slight striping on the edges, I'd bet that's got to be it. I just got it from Northland Rosarium, so maybe at some point I will be able to compare it for you. It's still pretty tiny tho. Might be awhile before I get any bloom on it.

I sent them an e-mail. I'll let you guys know what I hear back. :)

That's normal for older leaves but if newer leaves look like that then it needs more water and less fertilizer, fertilizer(salt) burn can also look like that.

That makes sense, given our water restrictions. Thanks.

As Ascot hits his stride, I'll have to add him to my list, just behind PAOK. Diane

Oops, forgot Royal Bonica (sport of Bonica). That one is hitting its stride this year, too. A bloom machine. Diane

You are of course correct - I think it depends on soil type, and mostly HUMIDITY. Here, in the summer we are so hot and dry that I have seen roses and other plants not die back, but just DIE completely, if the top growth is not substantially reduced, and lots of water given. We have clay soil also, but the air is so dry (unlike many parts of the country) - I think that is the problem. We do not (even when we are not having a drought) get any rain at all (truly) from May through October, so watering is essential. Thanks for reminding me that the answers to most questions on here totally depend on local conditions!

I moved three floribundas in bloom in mid-June a year or two ago, and they did fine. I did not prune them back. I watched for sevl days of cloudy & cooler weather, prepared each new hole before digging up each bush , dug up as large a root ball as possible (we use three spades plus a big piece of plywood as our "transplanting board") (altho generally we get larger root balls when moving perennials than roses), watched daily for several weeks and watered at first sign of any wilting. I think I lost only one leaflet from one bush. Granted these were not particularly robust, having less than a huge amount of foliage to be supported by the root system.
