Sow and Plant

Start indoors and transplant outdoors into a hill or mound after the soil has warmed. In warm climates peanuts can be direct sown in spring and summer.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.


Peanuts require at least 120 days of hot weather and ample rainfall to crop well. Regular hoeing is needed, because the stems of peanut flowers bend over and “plant” themselves in the soil.


Harvest when the leaves turn yellow and die back, or immediately after the first frost. Shake off soil, gently rinsing if necessary, and dry the whole plants in a warm, well-ventilated area for one to two weeks. Remove the peanuts, and continue drying them in a single layer until the shells are crisp. Moldy nuts should be disposed of immediately as they can be toxic.
