Here are additional photos of the damage.

I’m stumped. What’s the cause, and what are my options? They are deep-watered with a hose, using a bubbler head, every week. By ”deep-watered,” I mean 30-40 minutes each.

I don’t think they were exposed to anything toxic during the reno; I mean, we put in new floors and painted the entire house. Nothing was done outside — the workers used a different patio area. They weren't in the back at all.

I feel terrible..

If those were mine, I would plant them in the ground immediately, after cutting them back to about 12" tall. Questions - is that wall they are planted on a Southern exposure? If so, and since your climate is "hot and dry", perhaps it is too hot for them on that reflecting white wall. Perhaps you could find a place for them to climb where there is some afternoon shade, so that they do not fry, no matter how much water they get?

Are those in pots??? If so, please get them into the ground! Or cut them back, so the pinched roots have less to support.

Leaves should be falling right now anyhow. And the recent hot weather with dry wind has parched them

Heat damage for sure. Need more water. They do need to be in the ground. Pots can get so dry water runs through them and doesn't absorb. Growing backwards occurred for me in cold climates that were too cold for plants to make any more forward. They could just hang on and gradually peter out. I think Ingrid had a hot version of this happen in So Cal when her property reverted to desert with sustained heat damage and watering never kept up.

In pots, soaking the whole plant pot base for several hours could rehydrate them and put them in shade until you get them in the ground.

Sunburn? I've lost not-rose plants in pots in late October when growth was slowing down and all of a sudden, a really hot and dry day and even though the pot was well watered overnight, evapotranspiration got turned on by the hot and dry and there just wasn't enough water to keep the ends of the plants alive.

eta: when emergency soaking, warm water gets taken up faster than cold water.

Yup, cooked. Heat damage. The only other alternative would be salt burn from fertilization. If the damage is the tissue closest to that lovely heat/light reflecting white stucco wall, then it's heat damage. If the damage tends to be more the newer, softer growth no matter where it falls in relation to the wall, salt. My vote, though, because of the weather pattern we've all been in the past week is the plant went from cool spring to "Bellows of Hades" summer and fried. If you can't plant them, then provide shade somehow to prevent more cooking. Perhaps stakes with a white sheet or shade cloth stapled to it? At least until you can plant. Good luck. It's really a shame to lose growth on developed Renaes and have to wait for them to grow it again. Don't cut them back and leave the burned foliage on the plants until you can alleviate the issue. They help shade the canes. Good luck!

We had a spell of very warm weather here in murrietta and i have some brown crispy leaves as well and yellow leaves too . it is especially sad on the ones that recently leafed out so beautifully !

i hope you can plant reneas soon . its one of my favorite roses

sorry for the errors the website is horrible on mu end !

The verdict is in, and it’s unanimous — they have to go into the ground!

I was thinking about sawing off the bottoms of the pots and planting them that way — there will be lawn surrounding them, so want to minimize open ground area where weeds could grow — bad idea?

I guess I’ll start digging tomorrow. They will get afternoon shade in their new homes.

Hmm… makes sense.. I want them train them horizontally, or close to it, along a boundary wall. How far from the wall should I dig the holes?

Rain is in the radar for tomorrow. Fingers crossed!

That depends upon how exposed and hot the wall is and what your limits of space and ability to provide something upon which to support them are. The ideal would be two or three feet from the wall to allow good air flow and heat dissipation. That's not always possible, so do what you can. Go out and stand against that wall while it's hot. Move out a foot and notice the temp. Repeat at two feet, three feet, etc. and notice how the temperature diminishes. How will you support the rose if it isn't against the wall? You could install metal stakes with horizontal wires like the horizontal rails of a fence. Or, metal stakes with something like this wire fencing attached.

Good luck on the rain! Fingers crossed!

I was thinking, a trellis? series of trellises? Problem with metal and wire fencing is that it looks unattractive in the bare spots … also, metal gets hot, doesn’t it?

Any reason why three spray-shaped wooden trellises wouldn’t work?

thanjs again.

One huge reason three fan shaped trellises wouldn't be sufficient is their durability. Those flimsy "redwood" or "cedar" fans last a couple of years then need replacing or reinforcing. The vinyl ones also deteriorate in UV. The metal and wire are unattractive for a season (maybe) but ONE Renae can fill a huge area if it's happy. You have how many? Are you contemplating trying to keep them pruned to the size and shape of the fans? You can easily create a wall of Renae with the posts and wire I pictured and Renae will EAT it quickly. Which is preferable? Immediate "pretty" requiring major repair/replacement in a few, short seasons, or immediate "not pretty" becoming a gorgeous wall of flowering Renae in a season, perhaps two and pretty much permanent stability?

You can always plant annuals in the bare spaces while they fill in. I just began to fill in a large tract of fencing in my yard last year, and the bands I planted are still tiny, but I grew lots of sweet peas and moonflower vines on it and will continue to do so while the roses take their time filling it in. In your zone, it should happen fairly quickly. The metal might get hot but it won't even come close to radiating the kind of heat that the wall will, and it will be covered before you know it anyway. Wood is always temporary and those fan shaped trellises that you just stick in the ground are going to be no match for the weight of a climber in your zone. I think if you go that route, in a couple of years you'll be cursing those trellises.

Wow… ignorance is not bliss. I stand seriously corrected.

We did have rain today — maybe 40 minutes of it.

i start digging tomorrow. Right now I‘m most concerned about not killing my Renaes. I’ll probably start with a cheapo trellis now, with the idea of replacing it with a metal/wire fence in a couple of months. Digging three holes for three very large potted plants is enough of a project for this week …

Congratulations! I'm envious! It's been cloudy, extremely windy and as cold as a personnel manager's heart all day here!

@SylviaWW 9a Hot dry SoCal I bet it will turn out great! The fencing might look less than ideal when bare, but it WILL be hidden by plants eventually. And that grid of wire fencing material is great for airflow, I have some tacked up onto my stretch of (wooden) fencing I mentioned above. It helps give me something easy to train the roses onto, and keeps them just a few inches away from the wooden fence to allow for some air movement. It looks a little weird now, but when it's covered in mature roses and clematis it should all but disappear. Good luck digging those holes, that's my least favorite part!
