What is the best care for roses and the best feed for them also?
I like to use a good organic based rose food as it feeds the rosebush and also helps build the soils for a good root zone home for them. Here in Colorado, I get a rose food called Gro-Rich Rose and Perennial Food, made by the Richlawn folks. Also we have a locally made organic rose food called Mile Hi Rose Food that is very good. Here are a couple articles for you to check out too:

How far down do I cut flowers off after they bloom so that they will grow flowers back? I am especially interested in roses, but any flowers will do.

After removal of several Rose Rosette affected plants, how soon can I replant roses in the same spot, or should that be avoided? Should the area treated before replanting with other types of shrubs?

I have a patch of yard that I want to turn into a rose garden/flower extravzganza. It has some grass but is mostly yard weeds. The whole yard is that way. I can't get a tiller to go through that stuff. How do I make this mess tiller friendly? Can you help me?
I would rent a Turf Cutter machine from a local rental outfit. Set it to cut down a good 2 inches or more. Run that over the entire area where you want the rose/flower garden. Roll up the matting of weedy stuff and haul it away. Then rent a heavy duty rear tines tiller. Till the soil up going one direction. Rake through it with a hard toothed rake and remove as many roots as you possibly can. Then I would dump several bags of good compost all over the area to a 2- to 3-inch depth. Till the area again going both directions. Water the area well and let sit for about 5 days. Lightly till the area one more time and you are ready to plant.
I have a lot of ants and the plant's leaves are yellow. I put some iron but it didn't work. It wilted the flowers.
If you haven't read it, this article may help: https://www.gardeningknowhow.com/plant-problems/pests/keeping-ants-of-flowering-vines-vegetables-and-flowers.htm Also, you may want to check your plants for pests, such as aphids. They can leave behind a sticky residue, called honeydew, which ants are attracted to. Taking care of the pests responsible will normally take care of the ants. Oftentimes, neem oil will help treat ant pest problems and is perfectly safe for use. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
What is the best mulch for roses?
I have used just about every mulch available for my rosebushes and for me here in Northern Colorado, I like gravel mulch. Not the lava rock stuff but 3/4 gravel that is either the regular light gray and off white mix or one called Colorado Rose Stone gravel. I also like the shredded mulches you can by in the bag at Home Depot or Lowes. The brown color is what I like but there is a regular color that is goldish and then the redish kind too. Here is a link to an article on this subject for you too: https://www.gardeningknowhow.com/ornamental/flowers/roses/best-mulch-roses.htm .
