Fill a glass container with tepid tap water. For best results, use a container with a wide top and a narrow bottom.
Cut two or three healthy stems from a creeping fig vine. Make the stems long enough to submerge in the water, with at least 3 or 4 inches remaining to extend from the top of the container.
Place the vines in the container. Strip the leaves from the bottom of the vine so that no leaves are submerged in the water.
Place the container on a sunny windowsill, but avoid locations where the vine is exposed to direct, bright light, which can scorch the vine.
Refresh the water as needed to maintain the water level. Replace the water approximately once every week to keep it clean and fresh.
Plant the creeping fig vines in a planting container filled with commercial potting soil when the roots are at least 2 to 3 inches long.
Place the container where the vine is exposed to bright, indirect sunlight. Water when the top 1 inch of the soil feels dry to the touch.
Move the creeping fig outdoors when the vine displays healthy, new growth.
