How to Grow a Potato Plant Inside

• 1). Acquire a large container. Depending on the type of potato you will be planting, you will need a container large enough to hold a full grown potato and wide enough to take in enough light. Before filling the container with soil, make sure there are small holes in the bottom of the container to allow for draining.
  
  
• 2). Place the container in front of a large window, or the window that sees the most light during the day. Cover the bottom of the pot with small rocks (to allow for drainage without making a soil mess) and then fill the pot one third of the way up with a mixture of potting soil and peat moss. Do not fill the pot all the way, as you will need room to continually fill the pot with soil as the potato grows.
  
  
• 3). Cut the potatoes so that each "seed" has an eye. Space them in the planter about six inches from each other. Depending on the size of your pot, you will be able to plant between four and five seeds. Cover each spud with about three inches of soil.
  
  
• 4). Water the potato plants daily. Do not drown them, but you must keep them moist. As long as the drainage holes remain clear, you should be able to water daily without the risk of mold.
  
  
• 5). Add three more inches of soil (in a mound around the potato plant) when the plant grows to be about six inches tall. Keep "building" the soil until the mounds are about two inches from the top of the container.
  
  
• 6). Harvest your potatoes within two to three months of growing. There is no magical sign signaling that the potato is ready for plucking; take it on instinct. Using your hand, reach into the soil and wrap around the spud and yank up. Then mash, sauté, steam, or fry and enjoy.
