Thank you Barbara. The other 2 are not getting hit all day like MP is so I think they are ok - they get about 5-6 hours, they are also bigger plants.

Do I just snip the burned leafs and hope for better weather?

You might leave the scorched leaves to shade the canes until the heat modulates.

Good afternoon all,

A not so happy update: the browning/yellowing of leafs has continued, even though the planter is now in a partially shaded area (morning sun only, shielded in the afternoon by a Japanese maple).

We had some rain last night and the heat is not as intense as last week, but it is still mid-late August weather here in Z7.

Continue to monitor with bated breath? Anything else I can do? Thanks in advance.

I would put a wire cage or several more sticks like the one in your pic) around it, and put shade cloth (you can get it at any nursery) over the sticks or cage (not touching the rose), for at least a week. Once it started to get scorched, the symptoms do not disappear overnight. After a week I would take off the shade cloth, but keep it where it is so it gets some shade in the afternoon. I would NOT cut off any leaves - just leave it alone, except for water and shade. It is a baby, and needs all of the leaves it has, even dead ones help shade the plant.

Agree with Jacqueline; only wanted to add that it might be a good idea to remove only the flowers and buds. Flowering takes a lot of energy from the plant,and since this one is so young and stressed out it might bebefit from not having to think about producing flowers right now.
