Many flowering plants, such as roses, hydrangeas, gardenias, azaleas, and some varieties of decorative vines, grow best from cuttings. Cut several six- to eight-inch angled pieces from each plant that you want to propagate. Remove the leaves from the bottom of the stem, scrape the sides slightly near the bottom, and immediately put the scraped ends into a jar of water. Then, dip the cut ends into a rooting solution, and place them in potting soil, firming the soil around the cutting. Keep the cuttings moist while rooting. When new leaf buds appear, transplant to any desired location.
