How to Use a Potato to Grow a Plant


Homegrown potato plants can be started by simply planting a potato in the ground. However, if the soil conditions aren't right the potato may rot before it gets the chance to sprout and grow roots. This problem can be avoided by starting the growth cycle indoors. Potatoes require very little care in order to begin the process of sprouting into a plant. As long as the potato receives plenty of sunlight and water, sprouting and root growth is almost guaranteed.

Step 1

Wait for a potato to grow sprouts. The time it takes for this to happen depends on the conditions of your home and the type of potato.

Step 2

Stick four evenly spaced toothpicks around the middle of the potato. The toothpicks should stick out far enough so they can rest on the rim of a jar.

Step 3

Position the potato so the toothpicks rest on the jar's rim. The potato should be suspended inside the jar and not touch it at all. Make sure the end of the potato with the most sprouts is facing up.

Step 4

Fill the jar with lukewarm water and place it in a sunny window. Water must be added to the jar every day to ensure it stays filled.

Step 5

Keep the jar in the window until the potato splits open and a new shoot emerges.

Step 6

Transplant the potato either in a planter filled with potting soil or a partially sunny area of your garden with well-drained soil. When you transplant, dig the hole just deep enough so the base of the shoot comes to the surface of the soil.

Step 7

Keep the soil moist at times during the entire growth cycle of the potato plant.
