How do you start a rose bush from another one?
run a piece of the old one and pull a sector of its roots out and plant that...
Cutting, layering & division are angelic ways to propagate roses quickly and easily.
For cuttings, use stems that enjoy recently had some flowers. A appropriate cutting length is about 7 inches, cut near a 45 degree angle. Remove the leaves from the lowest half chunk of the cutting. Alow two or three leaves to remain at the top.
"Roses root best if the cutting have some leaves still attached, to provide sugars from photosynthesis as well as root-promoting hormones. Some varieties will root from leafless cuttings, but it's better to allow two or three leaves to remain. "

Don't allow the adjectives to dry, or expose it to temperatures that are too high or too low .
Difficult variety often benefit from wounding the base of the adjectives, either by making 1/2- to 1-inch vertical slits through the bark, or by slicing a strip of yap off one or two sides of the base of the adjectives with the clipper blade. This helps convey out roots all along the wound.
Dip the cutting surrounded by rooting hormones to improve the success rate.
You'll obligation to maintain adequate moisture, both contained by the soil and in the form of humidity in the upper air. Place the cuttings in pots of moist sand, potting soil, or a perlite/peat mix, then cover them near a plastic bag, or inverted two-liter soft drink bottle with the top cut stale, creating a small tent or "greenhouse" to maintain high humidity around the cuttings. Make sure the plastic is not touching the adjectives at all. Avoid overheating & keep out of direct sun. Put the cuttings within bright shade, such as against the north wall of a building or under a tree, to allow rooting without too much steam build-up. Once roots have developed, remove the plastic covering.
Most cuttings root best in the spring or rash summer, when the weather is warm but not miserably hot. Early in the season, some variety will have good roots surrounded by as little as two weeks & most varieties can be rooted in three to four weeks. At other times the process take longer -- up to seven or eight weeks.
It's best to divide roses by April-May.
Air or soil layering can produce roots in 28 days.

Here's a forum on getting rose cuttings to root:

P.S. If you don't use the tent/greenhouse method for your cuttings, you'll need to provide humidity to the plant (by misting) & you'll own to make sure the soil doesn't dry out.
Good luck! Hope this is helpful.
Answers: Take a cutting of newer wood. Not the old brown stuff and not the unadulterated green stuff just the wood in between. Make it the size of a pencil. Dip the bottom come to an end in rooting hormone and stick it in some honest potting soil. Keep it moist. The cutting should look like a pencil sticking surrounded by the dirt. No leaves!! It will grow or die. A good rule of thumb is if you just do 1 or 2 they will die. If you do abundantly they will all live and you will not know what to do with them. The best time to do this is within the spring when you trim your roses but if its a friends and you just can't wait step for it. In the spring you have more to work with because you own everything you cut off to work with.
