Hi friends!
What happened to my Ros?

Exactly what type of Rose is it? It looks like a miniature rose of some type but I can't say for sure.
Plus the soil that it is planted in appears very dry.

Appears to be maybe a leaf spot or some kind of insect, pics aren't clear enough. With Big Bill, looks very dry.

yes, miniature rose

What has the weather been like? If it has been very hot it could be sun burn. It needs more water.

What Seil said.

It really looks to me like this plant needs more water, but I don't know what your conditions are, at this time, in Iran.

It also looks like you may have some spider mite damage which also comes about when a rose is dry. Water it and give the leaves a good water also and check the back to see if there is some debris on them or any small red spider looking things.

Not sure if other people would agree but maybe watering/spraying the leaves in the morning could help out with the dryness (:

Might knock off some bugs too

In a dry climate I think that would be fine. I don't dare do it here, we have too many fungal diseases.

Lynda, there has been some research that says washing the leaves can actually help prevent fungal diseases. The thought is that it dislodges the spores so they can't take hold.

Very interesting! Hadn't read about that.

This is interesting as after it rains substantially the fungal diseases seems more spread out than before rains.
I have been told that the fungi just get spread by the rain all over the garden.

The fungal spores are in the soil. If it rains very hard those spores can be splashed up onto the leaves. Which is why black spot usually starts at the bottom of your plant and then moves upward. But the spores are also floating in the air and land on the leaves. Washing the leaves can remove those spores before the weather conditions are right for them to grow.

OK - here's my story. In early summer, I power washed and stained a elevated deck. I have 11 roses planted below the deck, all in a straight line. Over the summer and to date, I have sprayed the deck with water about every 2 days. Inevitably the roses get sprayed also. What I noticed, is none of the roses showed any signs of blackspot. I wish I could state that as to the rest of my garden beds as I live in blackspot heaven. It seems as though, I can attribute the "control" of blackspot to "frequent" overhead watering that does not appear to allow for the spores to fasten to the leaves. The key word may be "frequent".
The pH of my water is 7.

Very interesting, splashed up.
Do you think that the right amount of copper and sulfur in the soil (or on the top side of the soil) can be detrimental to the spores?

I don't know. I have never used copper or sulfur on my roses. If you think you are going to get rid of mold or fungal spores you can't. They are out there everywhere, in the soil, the air, other plants, everywhere! They are a natural part, and sometimes a very necessary part, of the ecosystem. The best thing to do is learn to live with them.

For example in the garden of my relatives certain trees were attacked by 3 fungal disease at the same time (can't remeber which they were exactly), while at the same time everything else had been also attacked, beans (leaves, pods, ect), tomatoes, etc. Those trees actually died, soon after, it was to expected barely had any leaves and the new leaves grow shriveled and infected.
Coincidentally lots of new soil was brought in from various sources to raise the ground level.
I was mainly curious about if the soil is poor on copper&sulfur compared to decent levels of copper&sulfur, how that impacts the level of infection. The roses were severely affected too, pretty much anything, wallnut trees, etc.

The only way to know for sure is to get a soil test done. Adding anything to the soil shouldn't be done unless you already know for certain that there is a deficiency and need for that particular compound. I have no idea what the soil conditions are in Romania so I can not give you advice on that.

Definitely not asking for an analysis of the soils in Romania :)
I thought there might be a theory behind it since the action of these elements against fungi is known, copper sulfate being used as a fungicide and these elements can be in the soil, compared to using contemporary systemic fungicides or *azole type of fungicides.

I use copper on my roses to control blackspot; you just control it, once your roses get it they always have it. Copper has proved to work better than most other fungicides and does less damage to the environment. I will be washing the leaves off in the spring and summer, however. I've never done this before but from what I've read here that seems to make sense to me. Can't do any more harm; might help!
