Hi! We have several roses and a couple of them have stems that are dying all of the sudden. We struggle w blackspot sometimes and I use copper sulfate to treat that. Otherwise, they have been healthy.

That black cane laying on the ground is dead. I can't tell if you have black spot or not. Can't see it in the pics or damage from it.

The woody canes should be cut back until you see life!
It may be too late in the year to do that now. Cut 2-3 cm off the tips, to see if they're alive.
Woody canes, will be pink, white, and have sugar liquid that you can see sometimes if you look closely.

Dead parts can be cut off and taken at any time.

Water wise, I water mine 1-2 liters every 3-5 days. Temps and humidity can prolong or shorten this time span.

Otherwise, yes it looks good! Green and some woody parts!
Hope this helps!

I don't see any black spot either. Black spot would not kill canes anyway. It kills the leaves but not the canes. What has the weather been like lately? Hot spells or cold snaps? Either of those cane kill canes. Take off any of the dead wood and keep it watered and if you are having very hot weather try and shade it during the hottest part of the day. A lawn chair over it can help.

Lol well I ve been aggressively pruning the leaves w Blackspot 😅. It is on the north side of my house.... we ve not had cold snaps, but is has gotten quite hot several days, and windy....maybe the heat swings? I did finally have to give up and water everything yesterday after a couple of days of threatening rain never came through. Thank you!!!!

No problem. I'm horrible. I get a pair of scissors (the small kind) and cut out the little spots. One more thing, Rose bushes being wet and humid over night can promote the growth of mildew. I made that mistake. I don't know if you know that, or if you did that, but I heard you say you watered after you were done. Best to Water them in the early morning.

Others may say it's ok, but that's up to you to decide.
Good luck and happy gardening!
