How to Grow Peanut

Arachis hypogaea

Tender Warm Season Single Harvest

Peanuts are a novelty crop in cool climates but very doable in a warm spot or polytunnel. Sow seeds (whole shelled nuts) in warm compost indoors, transplant after last frost into loose sandy soil. The unique flowering habit sends pegs underground to develop pods — keep soil loose and weed-free around the base. Harvest when leaves yellow; dry whole plants for 2–3 weeks before shelling.

When to Start

Start seeds indoors 4 weeks before your last frost date. Transplant outdoors once night temperatures stay above 13°C and soil has warmed to at least 18°C.

Care Essentials

  • Apply a low-nitrogen balanced fertiliser at planting. Avoid high nitrogen which promotes leaves over pods. A light calcium dressing (gypsum) aids pod shell formation.
  • Peanuts flower above ground but then send down specialised stalks called pegs which push into the soil where the pods develop. Loose, sandy, stone-free soil is essential so the pegs can penetrate easily. A warm sheltered site or polytunnel gives best results in cool climates.
