Well, this is the lowest tech advice you can follow. You can find it discussed here on GW if you search "spider mites". The mites love hot, dry and dusty conditions. Your plants are water stressed, that's a given. Get out early in the mornings with a water wand and drench the plants with plain old water. The water wand permits to to flush the under sides of the leaves where you'll find the webs and most of the mites. Wash them really well and repeat this a couple of times a week at first, then you can probably taper off. You'll be cleaning off the dust, dirt, chemicals, smog and bugs with their webs as well as hydrating the plants. Leaves take in water just as they release it to the air. Bathing your roses will jump start them like you won't believe. You'll drown many of the insects and make conditions so unfavorable for many others, they'll leave. Why put any more chemicals on the plants or in your garden during this heat when what will most likely be the most beneficial and effective is good old fashioned water? You do need a water wand for best results. You need to be able to reach inside the plant and thoroughly rinse off the backs of the foliage. Kim Here is a link that might be useful:

I was in a hurry last night when I responded. The plant in the first pix looked like 'Choc Soldier' to me then. That's why Jeff is referring to his decoder ring not seeing it. Ha ha! I was wrong. Now, seeing last pic, it looks like K. tomentosa, as he said earlier. Sorry for confusion!

Well the flower form eliminates Mulberry and Crab Apple. Both cherry and almond are Prunus species so my suggestion still stands. It will not show fruit until the flowers are pollinated. And the seeds are the pits inside the fruit. When it leafs out perhaps you could show us a picture of a leaf or two.

Could also be some kind of black spot. There are many strains of it depending on which part of the country you're in. It's really hard for me to tell the difference between BS, cercospora and anthracnose so I try to find a fungicide that will work for all of them and use that. Look for the Bayer Disease Control for Roses and that should do the trick. Stay away from the combined products that say 2 in 1 or 3 in 1. You don't need the extra stuff and they don't work as well.
