I am in need of help, I need an honest opinion on if I should just cut out the entire rose Bush or if you think it can be saved. The first year it wasn't doing good I had to cut out most of the plant due to extreme discolored stems from rotting and mildew over the summer. And over this summer I believe its gotten worse almost all the stems of the plant are turning yellow and black or have had a deep maroon coloring. Last year it had lots of bloomes. And this year there was only 4 and they didn't even mature right if that makes sense. And when it came time for the buds to bloom they where a complete jumbled mess that didn't even closely resemble what a rose should look like. I'll post photos too. Hopefully they turn out clear. I appreciate any and all help! Thank you!
Also all the white powdery buildup on the leaves is actually a mixture of milk and water that I have been using to get rid of powdery mildew.

How much sun does it get? Ideally it should get 6-8 hours of sun.
Looks like it's quite shaded and also being choked out with all the other plants at it's base, impeding the air flow around the plant. If you can clear some of that out, you can then add a layer of compost mulch and cut the rose back in the winter, maybe by half.

I suggested your question be moved to the rose forum where you are likely to get more attention.

Agree with Calif_Sue that this rose looks like it is being choked out by the plants at it's base. These are probably impeding the air flow, but also competing too much for the soil nutrients and moisture. I'd clear them out from close around the base of the rose,leaving at least a foot of space between the rose and the other plants, then I'd fertilize and mulch the rose,as said before.

But those dark blotches on the canes remind me of what we saw here years ago, when we had a severe outbreak of downy mildew.
https://www.google.com/search?...

We got a drench for that, but when the stuff melted the surface of a plastic measuring spoon, we gave up that idea. Instead, we did what local avocado growers do for avocado root rot (a closely related fungus). We got FRESH horse manure from a stable. Piled it around the base of the plant, from a few inches away from the base all the way to the drip line. That did the job.

I agree that the plants all around it need to be cleared away, and I would feed the rose. And you need to cut off all of the dead canes. (Dead stuff isn't helpful.)

I would also ask what rose this is?
How old is the plant?
What did the blooms look like LAST year?
What did the blooms look like THIS year?

We actually just got this house about 2 years ago so I have no idea what type of rose it is or how old unfortunately....but thank you all for the info I figured the other plants had something to do with it. I'll see what I can do about it later today.

It hade a lot of beautiful blooms last year. I even found a bud that had just bloomed that had second bloom growing from the middle of the first. And this year it had very few blooms and I guess I would say they resembled crumpled up tissue paper when they bloomed this year and didn't last long.

Any ideas on how I would control the Honey suckles though I've grown attached to them because they are one of the only things I have left that remind me of my Grandparents and where I grew up. They grew wild all along the house in our back yard. And now that they have both past and I won't ever be able to go back to that house since my grandmother sold the house after my grandfather died because it was too much for her to be able to stay on her own or with my mothers help. So I really don't want to have to take the whole plant out. And they grow large pretty fast here.

Well, that might just not be a good place for a rose, then. (Life's full of choices,)

Is that bloom you showed the "deformation" you were mentioning? That's called "proliferation," and some roses will do it.

Were this year's blooms the same color as last year's blooms? Last year, they were pink. Were they still pink, this year?

And . . . . Did you plant this rose, or was it there when you bought the house? If you planted it, can you remember its name?

That bloom was from the year before and yes the blooms where still pink but very faded and the blooms from this year look 2-3 times worse then this photo. And the rose was here when we got the house.so I have no idea of the name

I can't tell if this diseased or if its just discoloration from it starting to get colder at night. Cause I know that roses start to turn a maroon color when they go dormant for the winter.

Also I was thinking about putting bricks 5-10 inches away from the base of the rose all the way around. And was curious if it was a good idea and if it would be helpful to stop the honey suckle from choking out the rose again or if anyone had any other ideas that doesn't involve cutting them completely out. As I have already cut out a large portion

Does the honeysuckle have something else handy to climb?

I'm sure I could figure out something for it to climb on. I could probably put up a lattice on either side.

That would probably help a lot...then get rid of or move all those dense, sword-leaved plants that are crowding around the base...
