That is some type of rose fungal disease. You would have to post a nice clear closeup pic for others to know for sure what fungal disease it may be.

It is normal for SOME roses to get these fungal diseases then to drop some or all of its leaves over a period of time.

Options in your case are to just ignore it and sooner or later the rose bush will grow new leaves.
OR
Spray leaves with a fungicide on a regular cycle throughout the growing season...

I choose not to spray here so someone else can help you with that info...

There is some black spot and I think I can see the start of some powdery mildew problems too. Look for the Bayer Rose Disease Control product (NOT the 2 in 1 or 3 in 1 products!) and give it a good spray following the instructions on the bottle carefully. If you are experiencing hot humid days and cool nights that's the perfect weather for these fungal diseases to show up.

That's undoubtedly sunburn. When heat waves are predicted, give your rose a soaking at the roots on the first day of the heat spell. That will help.

Did you fertilize recently? If so, flush the soil with plenty of water. Excess nitrogen in ammonium form produces this look. Heat, scant water, and fertilizer can all contribute to burn. The plant will recover.

Very beautiful.my mr Lincoln is plagued by pm

That will make you want more.

With my space constraints if I did that I'd never be able to plant another rose! I reuse holes all the time. I've never noticed any problem in doing so. I reuse pots and potting soils too. Same thing...no problems.

I reuse holes too... I figure if one rose grew well so would another one...

Are you sure you don't have fig beetles? I have seen them eat rose blooms?

How big are they? What color are they?

I've seen Hoplia Beetles and Fuller Rose Weevils here but in the forty-five years I've lived in and around Los Angeles, never have I encountered a Japanese Beetle. Thank heavens! Fortunately, both of the former are fairly cyclical. Some years I seen virtually none, others they are obviously present, but never to the extent Japanese Beetles are elsewhere in the country. I don't do anything about them other than to squash them by fingers. Kim

It sounds like a once blooming rose. They only bloom on old wood. Usually those are pruned only AFTER they have bloomed out for the current season. However, if it hasn't bloomed yet and you don't see any buds forming on it yet it may not bloom this season so pruning it now should be fine. It could be that this past winter killed off the year old wood that would have bloomed this season. It was a very nasty winter.

Take out any dead wood and cut it down to the height you want then leave it alone to grow back new wood that should bloom next year. Yes, keep it watered and fertilize it. If you have any pictures from last years bloom post them and maybe we can ID it for you.

Yes, I think it's a one bloomer.
I didn't deadhead this year, so it's stopped.
I'll trim the baby down and see what happens.
Thanks for the suggestions!

I also have had very good results from my Climbing Pinkie....never has disease of any kind.

Thanks Seil, it certainly has been a learning experience. I watched Paul Zimmermans video on you tube in training climbers and it was very informative so I hope it works out like it's supposed to lol.
Molly I would love to see pics of your pinkies.

There could be any number of reasons why that first bloom is skimpy. It's too new a plant to decide yet if it's a mislabel or not.

Well I now have some good size blooms coming along, as shown in the pictures below. But I also have another question, what could be causing the yellow leaves on the plant?

I know over/under watering could be happening although I know it is not under watering. And also I read it could be because of light not getting to those leaves due to the leaves at the top of the bush.

I know the rose is doing well due to all of the new blooms and growth going on, just not near the bottom.

Thanks

I have heard the 'acidic clay soil means no Dr. Huey' but I can attest that the Dr. Does quite well here in our red acidic clay. Too well, in fact.

Buford,

Huey will do well enough in acidic clay, but my real concern is that it is not very suitable to colder climates. It will typically decline rapidly or die off altogether in 3 years up here. I can't really say how Huey performs in US zone 6b long term as I have no experience in such a scenario, but I do know that multiflora will not have any cold related issues and would probably be better suited overall when you add acidic clay into the mix.

Thank you Frances for the detailed instructions on planting bands. I just ordered two bands from Rouge Valley for delivery next week.

If I understand correctly, I will pot these bands up into one gallon containers, keep them watered and fertilized, and set them outdoors in a sunny location until October. Then bury the potted plants in my garden, mulch the first several inches, and leave them through winter. Come spring I can dig up them up, remove the pot, and transplant into their final location.

I also have a home in central NJ, so I'll plant one there and one here at my Virginia home.

Tom

You are very welcome, Tom! Your understanding is correct. As I said, I have used this approach for many years and never lost a little rose yet! I hope it'll all work out as well for you. Please send us an update in spring. If you are inclined to take pictures, I'd love to see photos of your Old Ports next year!

All best,

Frances

Very pretty!!!

Ooh!!!!! Lovely.

Roseseek, there WAS a diesel vehicle idling by the bush this week!!! I suppose if the leaves are sticky, they can pick up the exhaust.

There was a vinca bush near the roses that was horribly infested with...what, aphids, white flies? When I yanked it I noticed stuff flying in the air, gnats or dusty stuff, not sure. Left a greasy mark on the pavement it had grown over. I sprayed the rose bush with water which didn't do much unless I rubbed the wet leaf between my fingers. It's on the old growth, not the newer growth. We'll see how it goes now that the vinca is gone.

Thanks everyone.

It's been a bad year for white fly here, too. Getting rid of the vinca should help relieve the water stress caused by the competition and eliminate their habitiat. I would turn on the hose to a trickle and wash all the yuck off the rose foliage. It will rehydrate the rose and help prevent the diesel from destroying those leaves. If you put down your fertilizer before you wash the foliage, you can kill two birds with the same stone...cleaning the foliage and watering in the food. Good luck! I'm glad it appears it was something simple. Kim

Zack is right, that's the good Doctor and if you don't take him out, right down to below the ground, he will eventually take over and destroy your rose.

Follow the cane(s) down to the ground and then dig the soil off of them and find out where they connect to the roots. At that point you want to RIP OFF the canes. Yank down and away HARD. Don't just cut them back because they will just grow right back again. You need to destroy the growth node so it will not send up another shoot.

Thanks for the replies. I did cut it off but I didn't do it right to the root. I will try tomorrow to get down to the root.

I think I remember seeing 'Mirandy' being sold in body bags last spring. I have never grown it, so I don't know if the picture resembles it. The picture does not look like Mr. Lincoln to me.

Your 2nd noid reminds me of The Generous Gardener.
