Jumbo Virginia Peanut (Arachis hypogaea) - Description
Tasty peanut with 1 or 2 extra-large nuts per pod. Vines spread 3 1/2' across, need 4-5 frost-free months and well-drained soil. Under favorable conditions, plant yields 50-60 pods. One lb. will plant a 75' row.
Jumbo Virginia Peanut (Arachis hypogaea) - Blooming
Blooms yellow flowers. After the flowers fade, short stems called pegs are produced which enter the soil where the underground nuts (fruits) are formed about 10 days later.
Jumbo Virginia Peanut (Arachis hypogaea) - Growth
Peanuts are warm-season annuals that grow best in climates that have long and warm summers. Full sun promotes vigorous growth. Needs soil temperature of 65ºF for germination.
Jumbo Virginia Peanut (Arachis hypogaea) - Planting
Seeds of the peanut can be sown, but be sure to sow seeds that have not been roasted. Remove the shells, but leave the peanut skin intact and plant them in the soil once the weather warms in spring. Or start seedlings indoors about 4 weeks before the last frost date in your area.
Jumbo Virginia Peanut (Arachis hypogaea) - Pest
Affected by nematodes, wireworms, and small animals like mice and voles. Rotate crops to avoid worms, and fence around plants to keep animals away. Rot diseases are common in peanuts grown in heavy wet soils. Leaf spot can also occur, particularly in hot humid areas, and causes premature yellowing and leaf dropping. Make sure to grow peanuts in well-draining soil or in raised beds to keep disease-free.
Jumbo Virginia Peanut (Arachis hypogaea) - Interesting facts
The Arachis genus is made up of around 70 species that belong to the pea family; however, the most infamous of all the species is A. hypogaea, aka the peanut. Peanuts are actually fruits that result from the pollination of flowers above ground. Once the flowers are pollinated, the developing fruit and its respective stem (called a peg) begin growing towards the ground. Eventually the fruit will be buried. This mechanism is to prevent herbivory.
Jumbo Virginia Peanut (Arachis hypogaea) - Soil and irrigation
Using soil that is light and airy (sandy soils) will promote better soil penetration by the pegs. Peanuts thrive in sandy, yet fertile, well-drained soil. Provide atleast 1" of water per week and more during dry periods. Adequate water is critical during peg formation. Mulch with 1-2" of straw once pegs enter the soil.
