How to Grow Peanuts Indoors

Peanuts are a great indoor plant. The plant itself is pretty, with yellow flowers on a full bush. It is easy to care for indoors. Many of the issues that may cause the peanut to be more difficult to grow outside, such as animals and weeds, are less likely to occur indoors. The plant can also be started indoors, then transplanted outside.

Instructions

    • 1
      Whole raw peanuts can be planted without shelling.

      Purchase peanut seed to plant or simply buy raw peanuts at your local grocery store. These can be planted whole or shelled. However, you may have more success at sowing seed peanuts bought at a gardening store.

      Choose a container for planting the peanut. If you want to plant indoors but then move the peanuts outdoors in warmer weather, your container should be around 6 to 8 inches in diameter. If you want to plant, grow and mature the peanut completely indoors, choose a container about 18 inches in diameter, large enough for the peanut plant to set pegs. Only plant one peanut in each 18-inch container.

      Potting soil is used for planting the peanut.

      Put potting soil in the container. Make a hole 1 to 3 inches deep in the soil and put in the peanut seed. If you are planting indoors with the intent to transplant outdoors in warmer weather, plant five to six seeds, not touching, in the 6- to 8-inch pot.

      Cover the seed(s) completely with soil and place the container in a warm, dry spot. Immediately water the topsoil. The soil should remain consistently moist through daily waterings until it begins to flower. After it flowers, only water when the soil is completely dry.

      Transplant the peanut plants you planted together in the smaller pot when they reach a height of 4 inches. You can replant them in individual containers or directly into your garden soil.

      Push the soil at the base of the plant into a mound when its height reaches 12 inches. This dirt hill will allow the peanut plant to set its pegs. These pegs are the part of the flower that elongates and becomes the pod.

      A garden fork is used to harvest the peanut plant.

      Watch for the plant's leaves to turn yellow. This means the peanuts are ready to be harvested. Use a garden fork to lift up the pods from the ground.This will cause you to pull up the whole plant.

      Hang the peanut plant in warm and dry place for a couple of weeks to allow time to dry. When the pods are completely dry, the seeds can be removed.
