How do I start rose cuttings?
Your best bet is to get a cutting of the bush itself, where the bush is green and about a big around as a round pencil. You usually want to get these about the time you prune the roses in the early spring. Cut the piece of the rose bush to a length of about 6 inches. Put half of it in some fertile preferably loamy soil and leave the other half sticking up above ground. Cover the part sticking up with a mason or canning jar pushed into the ground about 3/4 inch. Water fairly regularly but don't keep it so wet there is standing water. The leaves will start to sprout on the portion above ground and the portion below ground will be developing roots. As the leaves develop in the jar leave the jar on if they start to turn brown, shade the jar from the sun where is only getting about half the amount of sun that it was. Wait a week or two and then take the jar off. With any luck at all you will have a new rose bush.
Reply:I fully agree with the first post except when and were to cut.

when you see buds coming on wait for the bud to almost open, then take a cutting from 3 to 6 inches, make sure its the soft green stem as old stems do not root as easily. also, a rooting hermone may help assist the cutting to root.
