Potato vines are decorative additions to anyone's landscape, and they are easy and inexpensive to grow. Give the plant a head start indoors on your kitchen windowsill, and before you know it, you'll be potting up a beautiful plant.
Take a sweet potato or white potato that has several eyes.
Stick four or more toothpicks or shortened skewers into the middle of the potato. Suspend the potato in a wide-mouth glass jar resting the toothpicks on the glass rim to support the potato. Fill the jar with water until it covers some of the eyes on the bottom of the potato.
Place the jar in an area with filtered light and watch the roots grow and the eyes sprout.
When the plant has developed a good root system and has grown at least three leaves on each sprout, move it to a pot and cover the roots and the potato with soil. Add other plants of differing textures to the pot to make a dramatic presentation.
Clip the ends of the vines when they reach eight to 10 inches long to encourage a bushier plant. Fertilize the plant on a regular basis and enjoy the beautiful results.
