Hi, it needs far less water... far less often. But it sounds now as if it might be a good idea to get it out of the pot, check for slimy black roots and cut them back to healthy ones if you find any, then repot in much faster draining soil (lots of perlite, or coarse sand - small gravelly stuff like aquarium gravel) and get it into more sun. And good luck.

Blackspot. The forum has LOTS of posts about it. Some roses are more susceptible than others. You can spray but you have to repeat every week or whenever the directions say. You must also collect and discard all affected leaves. The spray doesn't get rid of the problem. Instead, it protects the new growth.

I honestly try very hard NOT to be overparanoid about things like this. I do not ever use anything in my garden except for homemade compost. I don't even add things to my soil as most gardeners do. I am also the person who uses steam to clean her house instead of chemicals when at all possible. I also figure though that for the times I do need to buy things in the stores, like right now when my garden is being moved and my canned goods are running out, I have little control over what they have done to the plants they grew my food on and they probably did WAY worse than a little copper fungicide. I don't have pets, but I do have a now 3 and 4 year old. Last year when they were 2 and 3 I didn't let them in the garden for the day I sprayed , but after that I let them back in. BUT, my kids also don't munch on leaves (well not of the tomato plants anyway) so I am not sure how I would feel about that. I am not sure what your plan for next year is, but I did my research before deciding to move my garden for other reasons. I was going to do solar sterilization. You will obviously need to do something otherwise you will have the same issue next year that you have this year. I will add a link below to solar sterilization. I haven't tried it, but with my tomatoes dying off early I figured I had enough time to cut my losses cover the garden up and bake the soil if I needed to get it ready for this year. I would be curious if anyone on GW has tried it. Here is a link that might be useful: Soil solarization

I sure wish someone would answer this because I have the exact same problem. Had it last year and it affected all my plants and I'm seeing it again this year already.
