How to Grow Your Own Peanuts from Store-Bought Nuts

Growing your own peanuts at home is a rewarding and enjoyable experience that can provide you with a fresh, healthy snack. Peanuts are a versatile and nutritious legume that can be used in a variety of dishes, from classic peanut butter to savory sauces and stews. By growing your own peanuts, you can ensure that they are free from harmful pesticides and chemicals, and you can enjoy the satisfaction of harvesting your own crop. In this article, we will guide you through the process of growing peanuts from store-bought nuts, including preparing the peanuts, planting them, caring for the plants, and harvesting and storing your peanuts.

Preparing the Peanuts

Selecting raw, unroasted peanuts

To grow peanuts from store-bought nuts, it is essential to choose raw, unroasted peanuts. Roasted peanuts will not germinate, as the roasting process destroys the seed’s ability to sprout. When selecting your peanuts, look for plump, intact seeds that are free from cracks, mold, or discoloration. You can find raw peanuts at many health food stores, farmers’ markets, or online retailers.

Soaking peanuts for 8-12 hours

Before planting your peanuts, you need to soak them in water for 8-12 hours. This process helps to soften the seed coat and encourages germination. To soak your peanuts, place them in a bowl or container and cover them with room-temperature water. Leave the peanuts to soak overnight or for at least 8 hours. After soaking, drain the water and rinse the peanuts thoroughly.

Reasons for pre-soaking the peanuts

Pre-soaking the peanuts is crucial for several reasons:

  1. It softens the seed coat, making it easier for the seedling to emerge.
  2. It encourages faster and more uniform germination.
  3. It helps to remove any dirt or debris from the peanuts.
  4. It allows you to identify and discard any damaged or moldy peanuts before planting.

Planting the Peanuts

Choosing the right soil

To grow healthy peanut plants, it is important to choose the right soil. Peanuts prefer well-draining potting mix that is loose and friable. Avoid using heavy, clay-based soils, as they can retain too much moisture and lead to root rot. You can purchase a high-quality potting mix from your local garden center or create your own by mixing equal parts compost, perlite, and vermiculite.

When selecting a container for your peanuts, choose large pots with drainage holes at the bottom. Peanut plants have deep taproots and require ample space to grow. A pot that is at least 12 inches deep and 12 inches wide is recommended for each plant.

Planting technique

To plant your pre-soaked peanuts, follow these steps:

  1. Fill your container with the well-draining potting mix, leaving about an inch of space at the top.
  2. Using your finger or a small dibber, create holes in the soil that are 1-2 inches deep.
  3. Place one peanut seed in each hole, with the pointed end facing down.
  4. Cover the peanuts with soil and gently firm the surface.
  5. Space the peanuts 6-8 inches apart to allow room for the plants to grow.

Selecting a sunny location

Peanut plants require 6-8 hours of direct sunlight daily to thrive. When selecting a location for your peanut containers, choose a spot that receives ample sunlight throughout the day. A south-facing window, balcony, or patio is ideal. If you live in a region with intense afternoon sun, you may need to provide some light shade during the hottest part of the day to prevent the leaves from scorching.

Adequate sunlight is crucial for peanut plants, as it:

  1. Promotes healthy growth and development.
  2. Encourages the production of flowers and peanut pods.
  3. Helps to prevent the plants from becoming leggy or weak.

Caring for Peanut Plants


Peanut plants require consistent moisture to grow and develop properly. It is important to keep the soil consistently moist but not waterlogged. To achieve this, water your peanut plants deeply and regularly, allowing the top inch of soil to dry out between watering sessions. The frequency of watering will depend on factors such as the size of your container, the ambient temperature, and the humidity levels in your area.

To determine if your peanut plants need water, insert your finger into the soil up to the first knuckle. If the soil feels dry, it is time to water. If the soil feels moist, wait a day or two before checking again. Overwatering can lead to root rot and other fungal diseases, so it is important to avoid keeping the soil constantly soggy.


To support the growth and development of your peanut plants, it is beneficial to fertilize them regularly. Use a balanced fertilizer that contains equal parts nitrogen, phosphorus, and potassium (NPK). A fertilizer with an NPK ratio of 10-10-10 or 5-5-5 is suitable for peanut plants.

Apply the fertilizer every 4-6 weeks, following the manufacturer’s instructions for dosage. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of peanut production. If you notice that your plants are producing an abundance of leaves but few peanuts, reduce the frequency or amount of fertilizer application.

Monitoring plant growth

As your peanut plants grow, it is important to monitor their development and watch for key milestones. After about 4-6 weeks, you should notice the appearance of yellow flowers on the plants. These flowers are self-pollinating, meaning that they do not require the assistance of bees or other pollinators to produce peanuts.

Once the flowers have been pollinated, they will develop into pegs that grow downward and penetrate the soil. These pegs, also known as gynophores, will eventually develop into peanut pods. It is important to ensure that the soil remains loose and friable around the base of the plants to allow the pegs to easily penetrate the surface.

Harvesting and Storing Peanuts

Signs of readiness for harvest

Peanut plants typically take between 100-130 days to mature, depending on the variety and growing conditions. As the plants approach maturity, you will notice the yellowing of leaves, which is a sign that the peanuts are ready to be harvested. This usually occurs in late summer or early fall, depending on when you planted your peanuts.

Harvesting process

To harvest your peanuts, follow these steps:

  1. Carefully dig up the entire plant, taking care not to damage the peanut pods.
  2. Gently shake off any excess soil from the roots and pods.
  3. Hang the plants upside down in a warm, dry, and well-ventilated area for 1-2 weeks to allow the peanuts to cure.
  4. Once the peanuts have dried, remove them from the plants and store them in their pods until you are ready to use them.

Storing peanuts

To store your harvested peanuts, remove them from the pods and place them in an airtight container. Store the container in a cool, dry place, such as a pantry or cupboard, away from direct sunlight and heat sources. Properly stored, unshelled peanuts can last for up to 6 months, while shelled peanuts can last for up to 3 months.
