The peanut (Arachis hypogaea) is not really a nut at all, but a legume that
grows much like beans and peas except for one fact. Although the peanut
flowers above ground, the pods (shells and fruits) form below ground. So how
do we grow them?
Peanuts are a warm weather annual plant and require about 120 days from
planting to maturity. The fruits develop very close to the surface, so they
are definitely not tolerant to frost.
Plant peanuts when soil temperatures reach about 65F. You can find some
varieties
in seed catalogs. If you plant peanuts you buy, you need to purchase
unroasted ones. Shell them and plant the fruit (the peanut), which also
doubles as the seed. Plant seeds in loose, well-drained soil about six
inches apart and two inches deep. Plants should emerge in ten to fourteen
days.
Although peanuts require a moist environment, take care not to over-water
them since even pods forming in saturated ground can sprout. Cultivate
peanuts with care, since the pods are very shallow. An inch or two of mulch
will keep most weeds out. Pull visible weeds by hand.
Peanut plants should bloom about a month after the plants emerge. The
delicate yellow flowers are pea-like in appearance. After bloom, the plant
grows a peg that carries the seed under the soil to grow and ripen to
maturity. Although individual flowers bloom for only a day, the plant
continues to flower throughout the growing season, so they shouldn’t be
harvested until the oldest plants begin to turn yellow. This usually occurs
nine to ten weeks after bloom.
To Conclude:
Choose your peanut type by how you intend to use it after harvest. The four
basic types of peanut are Runner, Virginia, Spanish, and Valencia. Each has
characteristics that help determine how it is best used after harvest.
