Watch your peanut plants about four or five months after planting. It typically takes this long for the plants to mature. When the leaves begin to turn yellow it is nearly time to harvest them.
Dig up a few peanuts when you notice the leaves yellowing and check to see if they are ripe. If not, check periodically until they mature.
Harvest your peanut crop before a hard freeze. Frost may destroy your crop.
Dig up the peanuts, which grow from a peg into the ground. Each peanut plant yields up to forty peanuts.
Dry the peanuts for two or three days before shelling. Fresh, raw peanuts contain a mild toxin and drying eradicates this.
