Snip a vine from an existing philodendron plant so the stem is 3 or more inches long. For the best appearance, choose a stem terminating in a few healthy looking leaves.
Place the stem in a vase, glass or bottle filled with water.
Leave the philodendron in any area of the house with moderate to high light, but out of direct sunlight.
Check the water level every few days. Water may evaporate if the plant is left in a sunny spot. Refill the water as needed, and change the water once a week to keep it fresh.
Trim off vines and leaves that turn yellow or brown.
