That looks like bacoppa, water hyssop, growing beneath the rose as a ground cover. If that's what it is and it looks that good, I would suspect lack of water isn't the issue. I can't see from the image well enough to determine if there are spider mites or not. What have you sprayed on the plants? If the tropicals are also reacting this way, I suspect it might be fertilizer (salt) or some spray which has been applied to them all, perhaps Miracle Gro fertilizer sprayed on the foliage? If you were in zones 9 and higher, I would chalk it up to severe sun/UV, which we are definitely suffering from this year, much more severely than in any previous year in my experience. You may well be experiencing intense heat and greater UV/sun than is traditionally normal for where you are, but for the plants up in the air to be so severely affected while the bacoppa on the ground to still look that good, I would think it's more an issue of something sprayed on the larger plants. What sounds plausible to you? Kim

Susan, my roses in the most direct sun are also doing that as well, although not that bad. We just finished 4 weeks of 35C+ (95F) weather, hottest steak was over 40C for 5 days (46.8C hottest day) after which those kinds of leaves where showing up. I attributed it to the weather but am very curious to hear what others think.
Interesting that michaelg brings up cercospora. Thinking back everything in this particular location had cercospora issues last year. Thanks michaelg I think it is time to replace the mulch and a little soil.

Newroses -- I remembered reading one of your postings where you said that PP was not introduced in Europe. Do you have any insight as to why?
Jim - thanks again. I did some readings on Rose Midge while commuting today on my phone. Yes, it looks I have RM galore in my garden. For whatever reason, Rose Midge was never on my radar. Oh, well....

To this in 2014...
Maybe something to try once in a while?? I'm too inexperienced to understand what the effects of frequent applications of 1 tablespoon of vinegar per gallon of water might have. It's, as Nik said in the thread linked above, a short-term solution. Maybe others can offer some sound advice on this method. It worked wonders for me and I feel fairly comfortable watering once or twice this way before the most important bloom in Spring. Maybe it will help deepen your reds.


Vinegar is 5% Acetic Acid. Applied properly in appropriate concentrations it can temporarily acidify the soil/water, releasing more nitrogen, iron and other nutrients which may be locked up in insoluble compounds due to alkalinity. Aluminum sulfate and nitrogen can both accomplish similar effects. All of them, if used improperly, can severely burn and out right kill the plant so use with caution. Kim

Ok! The men are the winners! Jim first, and ken : Easy Livin, it is. Well done!
And thanks to hoovb, on an older thread, I will not leave it in a pot, but transfer it to a spot where it may soar to six feet. ( hoov, really- truly?)
Glad to see my instinct won out! Thanks for playing!

Per Help Me Find, Apple Blossom is a sport of the original Flower Carpet. Yours seems to be reverting to the original. Kim

Jason, we need to know where you live. There are a lot of things that can affect blooms and a lot of them are condition related, like disease pressures, soil and weather. Knowing where you live will helps us determine what conditions the rose is growing in. Then we need to know exactly what you see that is wrong with this rose. The leaves look fairly healthy. The buds are a little droopy but some Austins are like that naturally. So I don't see what the problem is.

hi to all who came back with comments...... we live in the south of England and for the past month or so its been quite warm and humid I will try suggestion of peeling back gently the outer leaves thanks to all of you any other comments much appreciated !!!


Hmm.. I'll have to check fragrance next time it blooms. I'm bad about that. I grow roses more for looks than smell, so I don't always check. I don't believe J&P is doing the test roses anymore. This past season was the first time they didn't offer them. One of my favortie test roses was HYPNOTIZED. OMG that one is gorgeous! And a good bloomer.

Several of the Austins might work for pillaring since they do like to get tall and leggy here anyway. You'd have to see which ones are more flexible. I have Golden Celebration and Graham Thomas and of those two Golden Celebration might work but Graham wouldn't. He's very stiff caned. The best advice you can get on how to do it is Paul Zimmerman's video.

I am going to second the Paul Zimmerman videos on YouTube. He shows you how to pillar a rose and how to care for climbing roses. I planted climber this year and have 3 going up the poles of my arbor. The videos are very informative and once you get the idea it's not so scary lol. I planted climbing pinkies to pillar and they have very lax canes that are easy to handle. I am also growing golden celebration as a climber and if you catch the canes early it would be easy to wrap around a pillar. Also look into Peggy Martin, she has very lax canes and is super easy to grow. Good luck and have fun!

About training New Dawn: I have given up trying as the canes are stiff and the thing is a thorny monster. As soon as I ties one cane down, another one shoots right up. But I am a newbie (and a untidy gardener), and for the record, I did see Awakening beautifully trained. I doubt I would ever acquire that skill (or have the needed desire/courage). I don't get too close to ND these days, and have given up dead heading it.

I'm not a bug expert, but I'm not a rose newbie and I am sure those spots are not fungus, but made by some kind of insect sucking sap of new growth or munching away at the leaves in odd ways. There are loads of them, not just aphids and larvae, there's a group of insects called heteroptera that cause exactly the type of damage your roses have in these pictures. They suck or eat on the tender new growth, and as the leaves continue to grow the damage show up as spots, deformed, curled up leaves, tiny holes, etc. You can't really prevent it, but you can spray some kind of insecticide if there are lots of this. Heteroptera insects aren't as easily detected as aphids and larvae, because they don't stay on the leaves and on the plant that much. When they are finished eating, they will wander off to a near by plant, perhaps come back later in the day, or next day. The make noticeable damage to new growth even if they dont come in huge numbers like aphids and larvae. You might have a few of them and they make their presence know if the decide to stick around.




Had to shovel prune one this week.. Will it affect all the other roses on my gardens?? I have 40 some David Austins.. The rose I shovel pruned looked exactly like this.
Worried also about the eden rose that has all the clusters have 7 leaves...no 3 or 5 and no blooms
welltraveled--just for you, I went out a few minutes ago and checked my Eden. Most of the leaves come in 7 leaf leaflets. I saw none with just 3 leaves. There was an occasional one with only 5 or 6 leaves per leaflet, but overwhelmingly, the leaflets consisted of 7 leaves.
I don't remember why that issue is so important to you, but I remember you posting about it before.
I do remember posting earlier that Eden is not a good bloomer for everybody. I don't remember how old your Eden is, but you may have to wait 3-5 years for it to do much--that is true for a number of climbers. Of course, none of this has anything to do with RRD. Sorry to hear, however, that you lost another rose to RRD. Many of us have had to go through that loss. It's hard to take.
As I said above, the mite that carries the infection gets blown, willy-nilly, around by the wind. It may blow the mite to the other side of your yard or several blocks away. However, there is no reason to panic that nearby roses somehow caught the infection just because they are nearby. Chances are, they did not--unless there is an infected rose somewhere in the neighborhood and the wind keeps blowing the mite carriers into your yard.
Hope that answers some of your concerns.
