How to Grow Peanuts
Peanuts are the gems of the South. You can find them in grocery stores and farmer’s markets everywhere, usually “green” and ready for boiling. Wonderful for roasting, too, or making homemade peanut butter.
And peanuts are easy to grow. Really, while you’re on summer vacation, these guys will be basking in the sunshine. Peanuts like it warm and are light feeders, however they do like their calcium. Be sure to supplement, say, tossing in a few crumbled eggshells at time of planting. You’re peanuts will be happy. And because they grow underground, be sure your soil is light and fluff–soft beds are always best!
After the last frost, plant your peanuts in the ground, about 3-4″ deep. Amend the soil with a bit of compost or composted manure, just to give them a good start. Note of caution here, if you live where the crows and critters are prevalent, consider covering your bed of peanuts with a screen material, securing it over them.
This will prevent the marauders from stealing your buried peanuts and sprouts. They will. I’ve seen them. The evidence is shown above. Once your plants grow to be about 4-6″ you can remove the screen. They’re safe now.
Water heavily until your peanuts set their pegs. Pegs are the spindly “legs” you’ll see dropping from your peanut plant after the appearance of beautiful yellow flowers. The peg is actually the flower’s stem and peanut embryo. It will bend toward the soil and bury itself. When it does, help out by mulching around the plants with hay/straw.
To harvest, check for peanuts about two months after the appearance of blooms. Similar to potatoes, you must poke around the soil GENTLY as you search for ripe peanuts. They are delicate at this stage, their outer skin papery and thin. Think about the skin of a newborn baby. VERY soft and delicate until it becomes accustomed to the air and sun. Same thing. If you find your peanuts are of nice size, ease the entire plant from the soil and shake excess dirt.
Lay out in the sun for several days, preferably on a screen or something similar to keep it off the ground. This will toughen the skin. Next up, separate the peanuts from the plants and place in a warm, dry spot for a few weeks. This will cure them and prepare them for storage. If kept in an air-tight container, your peanuts will last for months. These are the same peanuts you can plant next season. Or, better yet, use them right away for boiling. Using fresh green peanuts cuts boiling time, considerably.
If you’ve never had a boiled peanut, try one. They really are worth the exercise, then start a batch of your own using the recipe found here on my blog. Southern Boiled peanuts are divine!
Other than the previously mentioned crows and critters, peanuts don’t have a lot of trouble growing. Crickets and grasshoppers seem to prefer other vegetables in my garden over peanuts. Occasionally, your peanuts will get spots on their leaves, maybe a fungus of some kind, but in my experience, the damage is minimal. However, if they suffer extremely moist conditions, they can develop a fungus known as aspergillus which in turn produces a toxin known as aflatoxin. Boiling can eliminate this danger, but it might be best to discard of the fungus-peanuts. Your call.
Good Companions: Beets, carrots, corn, cucumber, squash.
Bad Companions: Kohlrabi, onions.
Health Benefits: Except for those plagued by peanut allergies, peanuts are quite healthy. Not only an excellent source of vitamin E, niacin, biotin and folate, peanuts contain resveratrol, the same ingredient found in red grapes that infamously make red wine healthy for the heart! Studies have also found high concentrations of antioxidant polyphenols, and that roasting actually increases the benefit of this antioxidant. Wunderbar! Just remember, they are high in fat, so consume in moderation.
