For the most part those roses look healthy to me. Do deadhead them and take off the yellow leaves and clean up any that have fallen and that will neaten things up considerably. If you've been experiencing the high temperatures, like most of us have, that could be part of he problem. Keep them well watered and give them a break. They might just be suffering from heat stress.
Never water roses from top, as that can make it more prone to brown spot.
I like to remove spent roses, as you would a regular rose. Esp if they're getting too big, but that's me. I think it keeps them healthy
Quail are causing problems here in Nevada in this drought. They are pecking my roses (the new ones) bare and I don`t know if some of them will live. This had never happened before. Now I have black netting around them from Home Depot. I tried the spinning pin wheels you get from $ Tree. That didn`t help. I have 3 tomato plants (no tomatoes yet) and one of them they are pecking. I found it lying on it`s side this morning. I put out a bird feeder, but the ones who flock to it are robins, so the quail are not eating from it. I too have a problem with the birds messing up the bird bath, and I am out there cleaning it up every day. I keep smelling saw dust from my bedroom and wonder if it`s a woodpecker. Oh, the problems of summer!
If you don't have grackles, count your blessings. They are noisy and can be aggressive if they think you are too close to their nest. I used to get dive bombed every morning as I crossed the street.
I live in an old neighborhood with lots of big trees and therefore, birds. They are everywhere, all kinds. I've seen a hawk snatch a morning dove in flight leaving a cloud of feathers. The most entertaining is the mockingbird who sounds like a car alarm.
What about 'Constellation'? It is a miniature rose, flowers a little more than 2" across, and said to be strongly fragrant. I just planted one, and it is nicely fragrant, unlike many minis. Flowers open with a yellow center, which fades. For me, 'Bolero' is turning out to be a dud, petals are always fried or damaged (botrytis?) and the bloom form can be gorgeous and perfect, but more often lopsided. I hear that 'Pure Perfume' is also small and fragrant, but J&P is always sold out when I want to buy one. What about 'White Licorice'? Starts out yellow, but in the hot sun turns white.
Here's the 'Constellation' that I just bought.
Bolero always looks like this for me, even in my dry climate, or maybe because of it. Even the buds have brown edges:
Noseometer,
Thank you for the suggestions and images.
I grew Pure Perfume and Bolero at my last home. I was not knocked out by Pure Perfume, although it was very healthy and can take a lot of summer heat. Bolero was stellar, but, it received filtered sun though a African Sumac during the hottest part of the day.
I actually completely changed the color scheme and made the area outside of that window a lavender rose bed.

I finally found my answer. I noticed that all my newly planted roses have sawfly. I first noticed the sandy coloured spotted leaves. I just snipped them off and hope it helps. I am beginning to regret buying all my roses from the same nurseries. It seems the new ones are getting sawfly and rrd.
If any of you are ever in the Central Florida area on a Saturday you must go visit them. I just got back with 15 roses. I make a trip up to them every now and again and am always impressed. Marilyn Monroe, Chris Evert, Lagerfeld, Neptune, Elina, Barbara Streisand, Love Song, Scentimental, Love's Promise, Let Freedom Ring, Bride's Dream, Marco Polo, Paradise Found, Colorific, and China Doll.
Buford: Where did you hear they were having a sale?
Have you checked upwind for a source of contageon? If a neighbor has a climbing or big rose or a field has a wild rose infected with RRD, the chances are that the vector mites will be dropped in your yard again, and the sad cycle will repeat.
There are places that winds will always drop mites, so long as the mites are sourced upwind.
What you need to do it try to reduce the chances of repetition.
It's not virus in the soil. It's the possibility that there were roots left behind and rose roots to graft onto other roses roots and spread their problems.
County agents? Some are good. Some are the folks who fifteen years ago published that Rose Rosette seldom affects cultivated roses so back then it was no danger.
Michael, haven't yet found any reference saying the nymphs don't pack much of a punch with their stab, so I'll assume the toxin/venom danger does include them as well as the adults.
Karen, couldn't tell with a casual look what was up with my buds & blooms, either. All that rain hadn't affected any other rose blossoms, but just as a precaution, and with that rose being new, thought I'd take a closer look. It went back into isolation. Spied a wheel bug nymph guarding it when watering yesterday. So just one of the original 5 unaccountable - though I suspect many more likely hatched from the large egg case & dispersed in different directions. Excellent photo!
Meredith, what stinging caterpillar do you have? Ann, your wheel bug took his time - wonder if that's typical or related to hunger level? Sources mention the ground beneath wheel bug home base plants littered with corpses that appear undamaged, as one clue to their whereabouts for collection & study.
Only the grandkids enthusiastically share a fascination with Nature. Just one local friend who gardens who's a keen observer - and she's a gem. So nice to pool our observations & curiosity here!

I forget the name of the stinging guy, but it is mostly white and hairy with small red parts, too. Those popped up a few years ago and make an annual appearance in one bed now.
My young wheelbug is still guarding his mulberry bush :D I'm going to have to name him at this rate!
Hi ingrid_vc... I am located in Madison, WI. We have had quite a bit of rain this spring. I haven't needed to water the roses even once so far this season. We seem to be getting nice soaking rains at well spaced intervals. It has been a very bountiful spring!
In Southern California, watering is now problematical. Where possible, I am watering with graywater. Heavy fertilizing is out of the question.
The weather is cool. There is a lot of overcast. I'd say, remove damaged leaves, water as much as you can, and don't feed them anymore, for the present.
They are rose slugs. Lots of roses suffer from them about this time of year. It is a annual event. Most gardeners just squish them and wait patiently for the good predator bugs to show up and eat up the rest of them.
The leaf damage the rose slugs do is rather unsightly at times--after the predator bugs have eaten up the rose slugs. At that point you may want to pluck off some of the most unsightly leaves, and then wait patiently for your rose to produce new leaves--which it will.
Usually that's it--until next spring/early summer when you will have to go through this ritual again, most likely. Happens to many of us. : )

Alfalfa meal is as if you put alfalfa pellets in a food processor or blender and ground them up almost to a powder. The Dr. Earth alfalfa meal also has added "Pro-Biotics beneficial soil microbes". From my reading, it looks as if the best thing for the roses is to buy pellets, make tea, and use the tea as a foliar spray. I don't want to undertake the making of tea, so will apply pellets and meal instead. I am thinking to put the meal in the amended soil used to fill my planting holes for roses and other things I need to plant soon, and to apply the pellets within and at drip line of established plants.
I bought a 50-lb bag of Arco brand pellets at a local feed store for $18.99. I also ordered the 3-pound box of Dr. Earth alfalfa meal on amazon for $11.71. The 50-pound bag of pellets measures roughly 5x16x24, whereas the 3-pound box of meal measures 7 x 10.75 x 2.375. I could not find much info online about Dr. Earth alfalfa meal, so (in case anyone is interested), I will paste in the notes I made from the Dr. Earth alfalfa meal box:
Dr. Earth #720 Alfalfa Meal 2-1-2, 3-pound box.
2-1-2 NPK or Nitrogen-Phosphate-Potash.
Also contains 7 kinds of non-plant food ingredients, e.g. Bacillus subtilis [a soil bacteria].
Supplies Pro-Biotics beneficial soil microbes.
Store in a cool dry place. Avoid direct exposure to light.
Vegetables, annuals, perennials, bedding plants:
a. New plantings: Mix into your soil amendment: 1 cup per 10 square feet. Till to depth of 4 to 8 inches, and water in.
b. Established: Side dress any time during growing season: 1 cup per 10 square feet of growing area. Work lightly into soil gently, and water well.
When potting up plants, mix 2 T per gallon of potting soil, or 1/2 cup per 1/2 cup cubic foot of potting soil. (1/2 cubic foot of is approx 5 gallons.) Mix soil and alfalfa meal thoroughly. Water well.
Established potted plants: 2 T for 6" container, or 8 T for 12" container. Scratch into soil gently. Add thin layer of mulch if possible.
New plantings of trees and shrubs: 2 cups per half cubic foot or 5 gallons of soil for filling the hole. Water.
Established trees and shrubs: 1 cup per inch of trunk diameter, measuring 4 to 6" above the soil line. Work gently into soil inside the drip line. Water.
May be used as compost starter.
Everything I've read says a minimum of six hours of sun, but you are so far south, that I think it would be OK, I'm in Dallas, and a rose on the back side of my house doesn't get that much, but it's really happy, Late afternoon sun, when it's in the 100s can be brutal,
Why is Mister Lincoln so intensely fragrant this morning? Sometimes the scent can be really faint but this morning it's really powerful. What are usually the conditions that make the fragrance more powerful? I haven't been able to find a trend.
It's been so hot and dry here lately that the flowers are burnt up.
Lovely HT roses, Growing rose without BS now that would be nice. Hope rust never shows up here.
