English ivy is beautiful and versatile vine that can be planted as an effective and fast-growing ground cover, where it can control erosion on difficult hillsides, and even climb up vertical surfaces such as walls or fences. It will also grow in a container indoors or outdoors, where it will cascade happily over the sides of the container. English ivy is easily propagated by taking a stem cutting in spring or summer.
Cut a 8 to 10-inch stem tip from a healthy English ivy plant. Pinch off the lower leaves and put the bare stem in a jar or bottle of fresh water. Although clear glass enables you to watch the development of the roots, cuttings will often root more easily in opaque glass.
Put the stem cuttings in a sunny windowsill. The water should be changed two or three times a week, because the Ivy cutting won't root in murky water.
Watch for the stem cutting to develop roots, which can take only a few days, or up to several weeks. Once the roots are at least an inch long, plant them in a pot filled with commercial potting mixture. Be sure the pot has a drainage hole in the bottom.
Put the new English ivy plant where it will get a few hours of bright sunlight every day. Allow the top of the soil to dry out between each watering, then water until the potting mixture is moist, but not soaked.
