It is best to space the rows about two feet apart, but wider rows can be made by off-set planting. Peanuts have relatively few pest problems, but keep them as weed-free as possible. Using a garden spade, carefully dig the plants and pick the peanuts out from the roots and pegs. Some gardeners lift out the entire plant and hang it in the garage for a few days to let the peanuts dry. Another option is to pick the peanuts off the plant and air dry them in a warm, well-ventilated room.
Children find it fascinating, and they also make a great snack.
I prefer fresh peanuts to those bought in the store. After they are harvested and dried, they can be stored for months for a home-grown holiday treat.
