The spots are probably blackspot. You will need to get a fungicide (such as Bayer Advanced Garden Disease Control for Roses, Flowers, and Shrubs--at Lowes) and a small plastic sprayer (2 gal. size) and spray those leaves.

As for the dried up brown bud, that is an old bloom that died and is drying up as a result. You can either wait until the bush decides to get rid of it (it will fall off) or if (like me) you don't like looking at that dried up bloom for any length of time, you can deadhead it--prune it off down to where there is green growth.

As for red growth, that is normal and beautiful. New growth on many (but not all) roses is often red. It will turn green as it matures.

Hope that helps. By the way, it is helpful if you tell us the general region you are from--gardening zone or state.

What growing zone you in cmg7843? Blackspots on your leaves is some type of fungal disease which roses can get in certain climates...

In our 6a growing zone when the weather cools and nutrients do not get to the plants as effective as they did in warmer weather fungal spots could appear right before leaves drop for winter.

When the flower is spent the petals of the bloom will fall off...

Thank you guys! I am in zone 6 just outside of Philly, PA. The red canes are normal then? They just showed up so suddenly and only on the top half with the affected leaves that has me worried.

Your about a 4 hour drive from me...Ours KO leaves have some spotting also which just started recently.

Red canes ok..

KOs with blackspot? What's the point then?

Ko's stay very clean here during our growing season April to late October than they might start spotting before leaves start falling off for fall/winter. Seems like when we start getting freezes and much cooler weather it happens... Sun changing positions in the sky, soil cooling... etc...

Some spots on ours are not BS but another type of fungus... Happens to most our disease resistant roses here not just Ko...

Jim should I treat with a fungicide or just let the roses go dormant? Any tips for winterizing them with these concerns?

I do not winterize or spray fungicides on Ko's...Next year they will be fine here until the weather cools in late Oct. again...

How long have you had your KO?

Thank you for advice!! My KO are barely a year old....hence the panicked newbie post haha. However they exploded over the summer and nearing 5 ft

They should be fine...lol...

Ours have done this the past 3 years...lol.. so its sort of a pattern here with Ko's and our other disease resistant roses...

Even some non rose bush type shrubs get spots here at this time...

Cool and damp = anthracnose. I only have four roses at the moment that are not affected. Those that are affected the worst look as those they have measles. When the leaf becomes highly infected it can get a few black spots as well. Anthracnose infected leaves do not yellow nearly as fast as black spot. If you have any black spotted leaves you can quickly tell the difference by looking at the bottom of the leaf. Spot anthracnose goes all the way thru the leaf. While black spot remains on the top surface and looks more like a shadow when viewed from underneath. Spot anthracnose is seen in cooler damp weather. For us when the dew point and cooler air keeps the leaves repeatedly wet at night.

In my opinion it's to late in the year to worry about treating the infection. Fungicides won't eliminate the spots that you have now. They do prevent new ones from forming but it's just to close to winter at this point. Thou I'm not certain of this I doubt the plant would affectively use a fungicide now as it is preparing to sleep for winter.

The first is black spot from Lady of Shallot

Now the backs

Now spot anthracnose,.the single leaf set is a newer infection so not much necrotic middle.

A little black spot on smallest leaf. Now the back

You can see the spots will go thru to the bottom. One more top photo of my measles as I call them

Also with a few black spots that have fuzzier edges up in the top right. Hope this helps. As far as I can till nearly every rose can get spot anthracnose if conditions prevail for too long.

There also appears to be some insect damage on some of the leaves.

I couldn't think of the name anthracnose...lol...So thanks Patty! Anthracnose spots here get shot-holes in the center of the spots sometimes also...

Yep the white spots/marks on the leaves is probably from rose slugs...

Thank you Patty!! Is there anything I can do to avoid anthracnose next year? My poor KOs have been having a horrible time with caterpillars. Every time I think I'm in the clear the little buggers reappear!!

cmg, first of all your welcome. Most fungicides that work for black spot will also work on sp or it will say on the label. I don't spray so can't recommend and I'm trying hard to keep my opinions about spray to my self. We must all find our own niche in the garden. Anyways if we're lucky the weather will be less conducive for anthracnose.

One more word on anthracnose the spotted leaves stay on forever. My out break occurred in late spring. The leaves are still on the plant as I type. growl

So I'm thinking I'll be needing a support team of organic gardeners in order to remain spray free.

Thanks for the advice Diane! I'm in new territory with these roses. Any flower or vegatable I can grow like a pro but for some weird reason I'm failing miserably with shrubs! RIP poor azaleas

My knockout looks similar. Don't sweat it.

It is wrong about getting a fungicide sprayer. It is not needed. In fact it will kill a toad instantly underneath the bush. Also, water should be in a bird bath.

Azalea need acidic soil and biotone makes azalea food. I have a dedicated blueberries area. I give them peat and coffee grounds and woodchips and a little garden sulfur.

Probably some black spot but it's also fall and they're slowing down and getting ready to go dormant. The leaves are getting old and ready to drop. They're not getting as much sun either because of shorter days and the weather is cool and damp. I wouldn't worry too much about it. Just take off the spotty leaves if you want and let them go dormant.

Patty - I never knew the difference between spot anthracnose and BS. That was really, really helpful!!
