When my sister was married, I took the half-dead roses from her bouquet. At home, I rooted them by cutting off the heads, making a clean cut on the bottoms, dipping the fresh-cut bottoms in rooting hormone, and putting them in a pot that was half Perlite and half soil. I kept these moist until rooted and then planted them in a shaded location in my garden. This year, on her first anniversary, my sister received a gift that can never be replaced: 12 rose bushes from her wedding bouquet.
Rose Bush cutting; Cut off a stem of the rose bush with a Y shape to it, cut a wedge out of a large potato, stick the rose cutting into the potato, then plant in the ground. The potato will keep the cutting moist until it grows roots, plus the nutritions from the potato, will feed the cutting.
