Add equal parts of sand, vermiculite, and planting mix to a nursery flat. Water the mixture until it's drenched. Poke planting holes in it for the cuttings, and set it aside to drain and dry until slightly moist.
Cut 4- to 6-inch stems from the ivy plant. New growth roots better than old, so choose stems that were recently produced.
Remove the foliage from the bottom half of the cutting. Dip the end into water, and then roll the bottom inch of it in rooting hormone. Stick the cuttings into the holes in the soil, to within 1/2 inch of the bottom leaves, and use your hands to pack the soil around the cuttings.
Set the nursery flat in an area that remains at least 70 degrees Fahrenheit and receives filtered sunlight.
Water the soil every day so it remains moist. The ivy should root within two weeks.
