They have a pulse.

Better focus on close ups of the foliage (undersides, too) may help with an answer to what you really want to know.

Dead roses don’t have leaves, so they are obviously not dead. The pictures are too indistinct to know if there is some health issue.

Thank you for that translation, floral. My spouse always reminds me I speak American, not English.

Have you been caring for the same roses for several years? Or are you a new owner of older roses?

The lack of rains in southern California the past few years has made a big difference in how roses look. Since two of your roses look bright green and the rest look water-starved, I suggest taking a close look for clogs and leaks in each and every sprinkler and dripper.

They look dry, and I agree with the above posts. Apple pie has some good suggestions. Diane

You really need to check every emitter while the system is going every year.

I use the 1/2” rain bird emitter line and it seems to be emmitting just fine. there is also a green one next to a dead looking one down at the end. it seems like its a fungus or disease or somethng. It almost has a frost look to it. Here are more pictures.

Spider mites?

Blackspot is the biggest problem in my area so that is what I have the most experience with but it kinda looks like powdery mildew to me

The first photo just above looks like powdery mildew, which often appears when plants are not getting enough water--especially in the arid West.

Looks like a pretty advanced case of powdery mildew. Some varieties are more prone to it than others, but in So. Calif., it tends to rear its head most with warm days and cool nights. Which, alas, is a lot of what we have, particularly if you are more inland. I do find that my roses respond well to being overhead watered in mid-day on a sunny day, which tends to help with the PM-prone ones. While some roses are more prone to PM, they will often outgrow it. What to do about it depends on your philosophy.

if these rose bushes are a different type

==>>>

as noted.. green leaves. .means not dead....

but many roses are grafted. and if you see different type leaves.. or different flowers.. the favored upper pplant.. may have died.. and the root stock is taking over ... and root stock is never a good rose.. else why would they behead it to graft soemthing else on top .. eh???

get a hand trowel.. or tablespoon.. run your water as you usualy do.. then go dig a half dozen holes down the line.. and FIND OUT HOW DEEP WATER IS GETTING .. and if you find that its not getting 6 to 8 inched down... then add time until it does ... and then dont water again.. until its drying 3 to 5 inches down ..

if you water in a method that encouraged deep roots.. then you will have healtier plants...

it always amazes me. how bugs and disease find stressed plants.. and improperly watered plants are stressed.. and your plant might be stressed because mildew is attacking ...

fert is rarely a remedy ... so keep looking and learning.. until you figure out what the real problem is ...

fert is rarely a remedy ...

==>>>

let me rephrase this .. its special with roses .. roses.. because of the heavy large flower show.. are heavy feeders. and a good fert regimen is recommended..

but for 99.9% of the other plants on the face of the earth.. they dont need that much fert ... unless you enjoy mowing your lawn every 45 minutes in spring.. lol

my point.. if i had one.. you are further ahead asking us for guidance.. rather than just dumping a bag of fert on your plants.. hoping for the best... so good work on that decision ....

The mildew is attacking because the plants are stressed, not the other way around. This is often the case in arid regions. Diane
