Peanuts: Best Climate for Planting

PeanutsPeanuts (Arachis hypogaea) are indigenous to South America and grow on the continent’s dry, long summers. But even if you don’t live in a tropical climate, you may grow peanuts. Hardy in the United States Agriculture Department plant hardiness zones 5b through 10b, it is adaptable to a variety of climates.


Temperature plays a key role in the development and production. Although they prefer warm weather, in areas with an average low winter temperature of -15 degrees Fahrenheit, peanuts are frost resistant and able to grow. In soil temperatures between 70 and 80 degrees Fahrenheit, peanuts hit their maximum growth quality. Through placing a 2-inch mulch layer on top of your soil, you can help maintain soil temperature. Flower development is impaired at temperatures over 93 degrees Fahrenheit and growth ceases entirely at temperatures under 57 degrees Fahrenheit. (If peanuts thrive in a cooler climate, place them on a south-facing wall to get the most heat.)


Peanuts are resistant of drought and should be planted after the year has stopped heavy rainfall. While they can tolerate flooded soil for a week, it should drain well so that water-logged soil does not impact rhizome production. For average, when the first inch of soil becomes clean, it should be given an inch of water once a week, but water them deeply. By laying rocks on top of your soil and spraying them with water during the afternoon, you can provide humidity for your peanuts.
