Pointsetta Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 21, 2023

The Poinsettia plant (Euphorbia pulcherrima) is a popular ornamental plant, especially during the holiday season. With its vibrant red bracts and dark green leaves, it adds a festive touch to any home. While most people buy Poinsettias as potted plants, it is also possible to grow them from seeds. In this article, we will guide you through the process of storing, sowing, and germinating Poinsettia plant seeds.

Storing Poinsettia Plant Seeds

If you want to grow Poinsettias from seeds, it is essential to start with high-quality seeds. You can either collect seeds from a mature Poinsettia plant or purchase them from a reputable seed supplier. When collecting seeds from a plant, make sure to choose healthy specimens with fully developed bracts.

To store Poinsettia plant seeds, follow these steps:

  1. Allow the seed pods to dry on the plant until they turn brown and start splitting open.
  2. Cut the seed pods from the plant using clean gardening shears.
  3. Open the seed pods gently and collect the small black seeds inside.
  4. Place the seeds in a paper envelope or a glass jar for storage.
  5. Store the envelope or jar in a cool, dry place away from direct sunlight.

Proper storage is crucial for maintaining seed viability. Poinsettia plant seeds can remain viable for up to two years if stored correctly.

Sowing Poinsettia Plant Seeds

Once you have stored your Poinsettia plant seeds properly, it’s time to sow them and start the germination process. Here’s how you can sow your Poinsettia seeds:

  1. Fill a seed tray or small pots with a well-draining soil mix specifically designed for seed starting. Avoid using regular garden soil, as it may be too heavy and retain too much moisture.
  2. Moisten the soil mix with water before sowing the seeds. The soil should be damp but not waterlogged.
  3. Scatter the Poinsettia seeds evenly on the soil surface. As the seeds are tiny, you don’t need to cover them with additional soil.
  4. Mist the seeds with water using a spray bottle to settle them into the soil. Avoid using a watering can or hose, as it may displace the seeds.
  5. Cover the seed tray or pots with a clear plastic dome or a plastic wrap to create a humid environment.
  6. Place the tray or pots in a warm location with indirect sunlight. A temperature between 70-75°F (21-24°C) is ideal for seed germination.

Germinating Poinsettia Plant Seeds

Poinsettia plant seeds require warmth, moisture, and light to germinate successfully. Follow these steps to ensure optimal conditions for germination:

  1. Check the soil moisture regularly and mist with water as needed to keep it consistently moist. Avoid overwatering, as excess moisture can lead to fungal diseases and rotting of seeds.
  2. Remove the plastic dome or wrap once the seeds start germinating, usually within 1-2 weeks. At this stage, they require ventilation to prevent damping off.
  3. Place the seed trays or pots in a well-lit area with indirect sunlight. A bright windowsill or a fluorescent grow light can provide sufficient light.
  4. Maintain a temperature of 65-70°F (18-21°C) during the day and slightly cooler temperatures at night.
  5. As the seedlings grow, thin them out if overcrowding occurs, leaving only the strongest ones.

Caring for Poinsettia Seedlings

After successful germination, your Poinsettia seedlings need proper care to ensure healthy growth. Here are some essential tips for caring for Poinsettia seedlings:

  1. Continue to provide bright, indirect light as the seedlings grow. Insufficient light can lead to weak and leggy plants.
  2. Water the seedlings when the top inch of soil feels dry. Avoid overwatering, as it can cause root rot.
  3. Fertilize the seedlings with a balanced liquid fertilizer diluted to half strength once a month.
  4. Transplant the seedlings into larger pots once they outgrow their current containers. Use a well-draining potting mix and handle the delicate roots with care.
  5. Harden off the seedlings gradually before moving them outdoors. This process involves exposing them to outdoor conditions like sunlight and wind for increasing durations over a week or two.

By following these guidelines, you can successfully grow Poinsettias from seeds and enjoy their stunning beauty in your home or garden.

Conclusion

Growing Poinsettia plants from seeds can be a rewarding experience for any gardening enthusiast. From storing the seeds to sowing and germinating them, each step plays a crucial role in ensuring successful growth. Remember to provide adequate warmth, moisture, and light throughout the process, and you will be rewarded with beautiful Poinsettia plants that will brighten up your holiday season and beyond.
