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.




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 the wrong plant in the wrong place. Harison's Yellow is at its best given a lot of space to spread out and make a good clump. It's nature is to be leggy and spread out, and mass makes it look better.
It is extremely unlikely that you will kill it by hard pruning. However, it won't bloom next year.

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.



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

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

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.



The hybrid tea part is apparently dead. The rootstock plant that survives will bloom next June, but it is not a good rose. I would dig it up and replant. The Knock Out roses are more hardy than the hybrid tea that froze out.
Grandma, it's getting awfully late in the season to plant anything new. For one thing, most nurseries won't have any selection left. For another the rose may not have adequate time to settle in before cold weather comes. Wait until next spring and pick out a rose you love to replace this one with. You can look for something that grows on it's own roots, so you won't have the root stock growing problem, or you can still get a grafted rose but plant that graft a good 4 or 5 inches below the soil to protect it from winter freezing. It still isn't fool proof but it will help for most winters.
Jeri is right. What you probably have is a HYBRID TEA not a TEA rose. They are very different and in your zone 5 a real TEA rose has NO chance of surviving your winters. They are extremely winter tender. But there are many HYBRID TEA roses that can survive a zone 5 winter if planted correctly. My suggestion is to look for some of the older varieties that have stood the test of time. They're still around for many reasons and one of them is that they are hardier then people think they are.
