When you have a healthy and vibrant ivy plant that is actively growing, use it to propagate new ones by taking softwood cuttings and rooting them. A softwood cutting is a cutting that you take from a new growth stem of the ivy plant. These soft stems root quickly and easily when you place them in simple potting soil.
Fill the planting container to the top with potting soil. Spray the surface of the soil with the spray bottle to moisten.
Select a softwood stem from the ivy plant. Choose a stem with both mature leaves near the base and newer and smaller leaves at the top. Bend the stem between your fingers approximately 8 inches from the end to break it off. If the stem snaps cleanly at the point you bend it, it's suitable for rooting.
Remove all but three pairs of leaves growing at the top of the stem to create a long, leafless stem for inserting into the soil.
Insert the bottom inch of the stem into rooting hormone, if you desire, but rooting hormone is not required to propagate the softwood cutting.
Make a hole in the center of the planting container and insert the bottom of the stem into the potting soil approximately 3 inches.
Place the plastic bag over the top of the planting container and secure the bag with the rubber band. Place the container in a warm location.
Spray the soil surface each day to keep it evenly moist.
Remove the plastic bag when you see new growth appear on the ivy stem. New growth indicates root growth beneath the soil. This typically occurs within three weeks.
Care for the rooted softwood stem as you would care for any ivy plant.
