How to Grow Peanuts at Home in Plastic Containers

  • Sunlight: Peanuts need full sun. Keep your container outdoors during warm months or on a bright balcony.
  • Water: Keep the soil evenly moist—not soggy. Reduce watering once pods begin to mature underground.
  • Feeding: Use a balanced organic fertilizer once a month, especially during flowering.
  • Mulching: Add mulch to retain moisture and protect the soil from temperature swings.

5. Watch the Magic Happen

  • Days 10–15: Sprouts emerge.
  • Month 2: Plants bloom with small yellow flowers. These drop and form “pegs” that push into the soil—this is where peanuts develop!
  • Month 4–5: Leaves start to yellow, and peanut pods mature underground.

🌾 Harvesting Your Peanuts

  • Peanuts are usually ready 4–5 months after planting.
  • When the plant starts to yellow and die back, stop watering for a few days.
  • Gently loosen the soil and pull up the plant.
  • Shake off excess dirt and leave the plant to dry in the sun for a few days.
  • Remove the peanuts, rinse, and air-dry fully before storing or roasting.

🌟 Tips for Success

  • Only use raw, untreated peanuts—not roasted!
  • Avoid heavy clay soil—it retains too much water and can rot the pods.
  • Peanuts grow best in warm temperatures (70–85°F or 21–29°C).
  • Protect young plants from snails and slugs if growing outdoors.
