Roses can be easy to grow from cuttings. I usually start them in winter from vigorous appearing dormant growth. I have also grown roses from a bouquet, that someone brought into work, mid summer, and from a roadside bush about to meet the bulldozer.
These are mostly from unnamed varieties that I grew from cuttings a decade ago.

It's an attempt to use the fig method, which works very well for me. The main difference is, this is Summer wood, while the fig cuttings are from dormant wood.
1. I pruned sections about pencil-thick and pencil-long, or a little smaller, from this year's growth.
2. I removed all leaflets, except the first couple in each leaf. The reason is, I wanted to leave a little for photosynthesis, but not enough to draw more water than the rootless cutting can absorb.
3. I made an incision in the lower section, where I want roots to grow. The incision is made with a sharp knife, through the cambium layer. Rose wood has a waxy layer, that may inhibit absorption of hormone. Making the incision also exposes the cambium, which may respond by making callous. Callous is basically a stem - cell type that can produce roots or vascular tissue, but not usually buds or leaves.
4. Dip in rooting hormone, 5 seconds.
5. Wrap in moist to wet paper towel. The paper towel is sterile, so will not contribute to rotting of the cutting. Moisture content is easy to manage. The white paper is easily inspected for mold and mildew, and easily replaced if those grow. When roots form, the paper towel is easy to removed, almost falls apart on its own, but wont cause damage if left in the growing medium to compost itself when the roots are growing.
6. The cutting is placed in a plastic bag. I blow up the plastic bag, so there is only minimal contact with the leaves, to reduce infection of the leaf with rot causing organisms. This makes a nice humidity chamber for the cutting, which should not require any watering until it starts growing and is removed.
7. I placed the plastic bags in a warm room. Easy to find in July, my house is not air conditioned. The shade is closed so there is not direct sunlight.
8. Now wait and see. If the paper towel becomes moldy, I remove it, rinse the stem, and replace with fresh wet paper towel. This is mostly the same as I do for figs. I have never done this for roses, so they might grow and might not.
My grandfather's sisters grew hybrid tea roses by starting cuttings directly in their rose bed. They cut sections, and stuck them into the soil. They covered the cuttings using a mason jar, to create a miniature green-house for each cutting. That was in the 1950s and 1960s, but I imagine they learned that from previous generations much earlier. 🌹
