De-shell the raw peanut before planting it. Soak the peanut kernels in water overnight. Fill the cells of an 11-by-22-inch seed-starting tray with potting soil. Make a hole approximately 2 inches deep in the soil of each cell.
Place one peanut kernel in each cell. If all the peanuts germinate, you can discard the plants you do not want to keep. Cover the peanuts with soil.
Set the peanuts in a sunny, warm location. Peanuts germinate at about 65 degrees Fahrenheit. Water the peanuts when the soil is dry to the touch. The peanuts germinate in two or three weeks.
Wait two more weeks after germination to transplant the peanut seedlings. Fill a 12-inch container with soil. Carefully lift the peanut seedling out of the smaller container and place it into the larger one.
Look for flowers about 45 days after transplanting. The flowers wilt, and pegs emerge that burrow into the ground. Do not disturb the pegs. They will produce peanuts in approximately 45 more days.
Dig the peanuts out of the soil when the plant's leaves turn yellow in the fall.
