Pandanus Plant Seeds:
Guide to Storing, Sowing and Germination

Updated: July 6, 2023

The pandanus plant, also known as the screw pine, is a tropical plant that is widely cultivated for its unique and attractive appearance. While many people enjoy growing pandanus plants for their ornamental value, others are interested in propagating these plants from seeds. In this article, we will provide a comprehensive guide on storing, sowing, and germinating pandanus plant seeds.

Storing Pandanus Plant Seeds

When it comes to storing pandanus plant seeds, it is important to ensure that they are kept in proper conditions to maintain their viability. Here are some key steps to follow:

  1. Harvesting: Wait until the pandanus fruit has fully ripened before harvesting the seeds. The fruit should have turned a deep orange or red color and should be slightly soft to the touch.

  2. Extracting the seeds: Cut open the fruit and remove the seeds. Be careful not to damage the seeds during this process.

  3. Cleaning: Rinse the seeds gently under running water to remove any pulp or debris. Pat them dry with a clean towel.

  4. Drying: Spread the seeds out on a clean surface and allow them to air dry for a few days. Make sure they are completely dry before storing them.

  5. Storage containers: Place the dried seeds in airtight containers such as ziplock bags or glass jars. It is important to use containers that can prevent moisture from entering.

  6. Labeling: Don’t forget to label your storage containers with the date of harvest and any other pertinent information.

  7. Storage temperature: Store the seeds in a cool, dry place where the temperature remains between 40-50°F (4-10°C). Avoid exposing them to direct sunlight or extreme temperature fluctuations.

By following these steps, you can ensure that your pandanus plant seeds remain viable for an extended period, allowing you to sow them when the time is right.

Sowing Pandanus Plant Seeds

Sowing pandanus plant seeds can be a rewarding and enjoyable experience. Here’s how to do it:

  1. Seed preparation: Before sowing the seeds, soak them in warm water for 24 hours. This process helps to soften the hard seed coat and improve germination rates.

  2. Seedling trays: Fill a seedling tray or small pots with a well-draining potting mix. Make sure the containers have drainage holes at the bottom to prevent waterlogging.

  3. Sowing depth: Place the soaked seeds on the surface of the potting mix and lightly press them into the soil. The seeds should be barely covered with a thin layer of soil.

  4. Watering: After sowing, water the seeds gently using a spray bottle or a watering can with a fine rose attachment. Avoid overwatering, as this can lead to rotting.

  5. Covering the tray: Cover the seedling tray with a plastic dome or plastic wrap to create a greenhouse-like environment. This helps to retain moisture and maintain steady humidity levels.

  6. Germination period: Place the tray in a warm location with indirect sunlight. The germination period for pandanus plant seeds can vary but typically takes anywhere from 1-3 months. Be patient and avoid disturbing the seeds during this time.

  7. Transplanting: Once the seedlings have developed a few true leaves, they can be transplanted into larger pots or directly into the garden if the climate is suitable.

Germination Tips

To enhance germination success, consider these additional tips:

  • Scarification: Some pandanus plant seeds have extremely hard seed coats that need scarification to break dormancy. You can achieve this by carefully nicking or sanding down a small portion of the seed coat before soaking them.

  • Bottom heat: Providing bottom heat to the seed tray can help speed up germination. You can place the tray on a heating mat or on top of a warm appliance like a refrigerator.

  • Regular monitoring: Check the seed tray regularly for any signs of germination or mold formation. Remove any moldy or rotting seeds promptly to prevent the spread of disease.

By following these guidelines, you can successfully store, sow, and germinate pandanus plant seeds. Remember, growing from seeds requires patience and care, but the reward of watching your pandanus plants grow from tiny seeds to beautiful specimens is truly worth it. Happy gardening!
