Propagate Roses - Cut 8 to 9 inches of a long stem rose at 45-degree angle. Remove spent blooms, leaves, or rose hips. Dip stem in cinnamon. Take a potato, remove any "eyes". Cut it in half and bore a hollow for rose stem. Plant about 4 inches into the ground or pot with moist soil. Cover with a glass jar. Planting on the north side will give the roses soft morning sun. Water to keep the soil moist, but do not soak soil. Transplant in about two months.
