Popcorn Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 8, 2023

Popcorn is a popular snack enjoyed by many people around the world. But have you ever wondered where popcorn comes from? Popcorn kernels come from a special variety of corn known as the popcorn plant. If you are interested in growing your own popcorn at home, it all starts with the seeds. In this guide, we will take you through the process of storing, sowing, and germinating popcorn plant seeds.

Storing Popcorn Plant Seeds

Before you can start sowing popcorn plant seeds, it is important to store them properly to ensure their viability. Here are some tips for storing popcorn plant seeds:

  1. Dry seeds thoroughly: After harvesting the popcorn ears, remove the kernels from the cob and spread them out in a single layer on a clean, dry surface. Allow the seeds to air dry for about two weeks. Proper drying helps prevent mold and ensures the seeds remain viable for longer.

  2. Store in a cool, dry place: Once the seeds are completely dry, transfer them to an airtight container such as a glass jar or a resealable bag. Place the container in a cool, dry place away from direct sunlight. A temperature of around 50°F (10°C) is ideal for storing popcorn plant seeds.

  3. Label and date the container: To keep track of your seeds, it is essential to label the container with the variety of popcorn plant and the date of storage. This will help you identify older seeds and use them first before they lose their viability.

By following these storage guidelines, you can keep your popcorn plant seeds viable for up to three years.

Sowing Popcorn Plant Seeds

Now that you have stored your popcorn plant seeds properly, it’s time to sow them and start your own popcorn garden. Here’s how you can sow popcorn plant seeds:

  1. Choose the right time: Popcorn plants are warm-season crops, so wait until all danger of frost has passed before sowing the seeds. The soil temperature should be around 50°F (10°C) or higher for successful germination.

  2. Prepare the soil: Popcorn plants prefer well-drained soil enriched with organic matter. Before sowing, prepare the planting area by loosening the soil and removing any weeds or debris. Incorporate compost or well-rotted manure to improve soil fertility.

  3. Sow the seeds: Plant popcorn seeds about 1-2 inches deep into the soil, spaced at least 8-12 inches apart. If you are planting in rows, space the rows about 24-36 inches apart to allow proper air circulation. Cover the seeds with soil and gently firm it down.

  4. Water thoroughly: After sowing, water the area thoroughly to ensure good seed-to-soil contact. Keep the soil consistently moist but not waterlogged during the germination process.

  5. Provide adequate sunlight: Popcorn plants require full sun to thrive. Make sure they receive at least 6-8 hours of direct sunlight per day.

Germinating Popcorn Plant Seeds

Once you have sown your popcorn plant seeds, it’s time to germinate them and watch them sprout into beautiful popcorn plants. Here are some tips for successful germination:

  1. Be patient: Popcorn plant seeds usually take around 7-10 days to germinate. Be patient and provide consistent care during this period.

  2. Maintain temperature: Ensure that the soil temperature remains around 50-95°F (10-35°C) for optimal germination. You may consider using a seedling heat mat or a greenhouse to maintain a stable temperature.

  3. Thin out seedlings: Once the seedlings have emerged, thin them out if they are overcrowded. Leave the healthiest and strongest plants, spacing them about 12-18 inches apart.

  4. Water carefully: Water the seedlings regularly to keep the soil moist, but avoid overwatering as it can lead to root rot. Allow the soil to dry slightly between waterings to prevent fungal diseases.

  5. Fertilize appropriately: When the seedlings have grown a few inches tall, apply a balanced fertilizer according to the manufacturer’s instructions. This will provide essential nutrients for healthy growth and development.

By following these germination tips, you can ensure a successful start to your popcorn plant garden.

Conclusion

Growing popcorn at home can be a rewarding experience. By properly storing, sowing, and germinating popcorn plant seeds, you can enjoy your own delicious popcorn harvest. Remember to choose a suitable storage location, prepare the soil well, and provide the right conditions for germination. With a little patience and care, you’ll soon be enjoying the fruits (or rather, kernels) of your labor. Happy popcorn gardening!
