How to Grow Peanuts

Peanuts (Arachis hypogaea) are warm‑season legumes that produce their pods underground. They thrive in full sun, loose sandy soil, and long frost‑free periods. This guide explains planting, germination, care, harvesting, and climate considerations suitable for all regions.

Where Should You Plant Peanuts?

  • Best location: Full sun; peanuts require strong light for vigorous growth and peg formation.
  • Soil: Loose, sandy, well‑drained soil; pH 6.0–6.5.
  • Moisture: Even moisture during early growth; reduce watering slightly once pods begin forming underground.

When Should You Plant Peanuts?

  • Start indoors: Not typical; peanuts grow best when directly sown outdoors.
  • Transplanting: Possible with nursery starts, but direct sowing is preferred.
  • Direct sow: Plant when soil is warm and frost danger has passed; peanuts need a long warm season.

How Do You Plant Peanuts?

  • Depth: Sow seeds (raw, unroasted peanuts in shell) 1–2 inches deep.
  • Spacing: Space plants 8–12 inches apart; allow 24–36 inches between rows.
  • Quantity: Several plants ensure good yields and continuous pod formation.

Which Plants Grow Well With Peanuts?

  • Companions: Corn, sunflowers, and light‑feeding vegetables.
  • Avoid: Heavy feeders that compete for nitrogen.
  • Best pairing: Plants that allow full sun and do not shade peanut vines.

How Do You Water and Feed Peanuts?

  • Watering: Keep soil evenly moist during early growth; reduce watering once pegs enter the soil.
  • Feeding: Minimal fertilizer needed; peanuts fix their own nitrogen.

How Do You Care for Peanuts?

  • Support: No support needed; plants form low, spreading vines.
  • Weeding: Keep beds weed‑free to maintain soil warmth and reduce competition.

Can You Grow Peanuts in Containers?

  • Container size: Minimum 12 inches deep and wide; deeper containers support peg penetration.
  • Winter growing: Not typical; peanuts require warm‑season conditions for pod formation.

What Pests or Diseases Affect Peanuts?

  • Pests: Aphids, leafhoppers, and caterpillars.
  • Diseases: Leaf spot, root rot, and fungal issues; ensure good airflow and proper watering.

How Do You Harvest Peanuts?

  • Timing: Harvest when leaves yellow and pods mature underground, typically 120–150 days after planting.
  • Leaves: Not harvested; foliage supports peg and pod development.
  • Seeds: Remove peanuts from pods; dry thoroughly before storing.
