Take an 8-inch cutting from the vanilla plant. It can be taken from anywhere on the plant, as long as it is healthy shoot.
Remove the leaves from the lower half of the vanilla plant cutting.
Plant the vanilla cutting next to, and in the shade of, the parent plant, allowing two leaves or leaf nodes to remain above the surface of the soil.
Pound a small stake next to the vanilla orchid cutting and loosely tie the cutting to it with plant ties.
Keep the soil moist at all times until the vanilla plant cutting has rooted. You will know this has occurred when there is new foliage.
