    Yellow spots could be fungus starting to attack. Spraying them with a fungicide such as Green Cure would be a good thing to do. Turn the leaves over and make sure nothing is munching on the backside. If you find some little bugs or worms, then spray with an insecticide or get some Bayer Tree and Shrub granules, apply per the label for ornamentals. Once scratched into the soils, water in well.

    The roses could be sending out what is called blind shoots that do not bloom, they just suck up nutrition and do not bloom. Or it could be that something is bothering or stressing the rosebushes. Here is a link to an article for you on this subject: https://www.gardeningknowhow.com/ornamental/flowers/roses/no-blooms-on-roses.htm

    Those are two beautiful roses by the way and such a grand contrast in colors! I hope they do bloom for you.

    I use both in my rose beds. I have one rose bed where I have brown shredded cedar mulch and others that have gravel mulch. I use the grey 3/4 rock in one and some Colorado Rose Stone in the other that is 1 1/4 inch, it is a white and rose pink gravel. I have found that roses do not like lava rock and it is too dark anyway. With gravel, you want to stay lighter colored so it does not draw too much heat in the summer or winter. Too much heat drawn to the soils in winter can kill the roses as they will try to grow when they should be taking their winter nap.

    Feeding the rosebushes with a fertilizer with too high an nitrogen content can cause this. I recommend feeding the roses with a good even NPK ratio organic rose food and water them well. Feeding monthly should not be necessary. Here are some links to articles that should be helpful to you: https://www.gardeningknowhow.com/ornamental/flowers/roses/rose-fertilizer.htm

    Prune out the wild light green canes as they are likely diseased or are actually coming up from the hardy root stock that is below the upper desired rose. Check out this article on grafted roses too: https://www.gardeningknowhow.com/ornamental/flowers/roses/own-root-roses-grafted-roses.htm
