Hello,
I am curious whats up with my ros leaves. I attached these photos for reference. I am aware of the black spot since we've had a few strong weeks of rain and humidity but I've never seen my leaves get so yellow with weird green spots in the mass as well as the burnt tips of leaves. Possible ideas: the 90 plus degree weather? Nutrient deficiency or abundance? Over watering? I have tried to find the issue online to no avail. At least from what I can conclude looking at photos. I haven't seen this combo of issues before. Any help with any of these issues is hugely appreciated.

Yellow leaves, green spots within yellow patches, dead patches, burnt tips and patches.



On my rosa Salita. dark patches. Some old leaves look yellow and reddish.

Lastly, These baby bushes I got 2 weeks ago, darkish patches on some leaves as well as then and others having a light and dark grainy look to them.

hi, I live in a hot, rainy state with lots of humidity. My rose leaves look just like yours! I don't think this is a nutrient problem, my roses are fertilized regularly, so I think it is the dreaded "B" word. Blackspot. I have found that once your roses get this, you have to be very vigilant in controlling this. Spray once a week with a fungicide, change fungicides every two years, pull all infected leaves, and if you mulch underneath your roses, replace the mulch every year. Start spraying as soon as the leaves emerge in February and spray until October, or until first frost. The problem with blackspot is that you can't really get rid of it once your roses have it, you can only control it. I do all of the above and I have gotten a handle on it.
I hoe this helps!
