All About Adiantum Laevigatum Plant Seeds: Germination, Storage and Sowing

The delicate and graceful Adiantum laevigatum makes a fantastic addition to indoor and outdoor spaces alike. While it’s readily available at most nurseries growing Adiantum laevigatum from seeds can be a rewarding endeavor. This fern propagates easily from its tiny seeds making growing it from seed a viable option for the home gardener. Here’s a comprehensive guide to Adiantum laevigatum seed germination, storage, and sowing for successfully growing this plant yourself.

Adiantum Laevigatum Seed Germination

Adiantum laevigatum seeds germinate readily when given warm temperatures, high humidity, and bright indirect light. Follow these tips for the best germination results:

• Soak the seeds – Soak Adiantum laevigatum spores in room temperature water for 24 hours before sowing. This softens the outer coat and initiates germination.

• Use sterile seed starting mix – Sow seeds in sterile, soilless seed starting mix to prevent fungus and diseases. The mix should be kept moist but not saturated.

• Cover with plastic – Cover the seed tray with plastic wrap or a humidity dome to maintain nearly 100% humidity around the germinating seeds.

• Provide warmth – Maintain temperatures between 65-75°F for best germination. Consider using a seedling heat mat.

• Give bright indirect light – Place seed trays in bright indirect light to encourage growth after germination occurs.

• Keep moist – Never allow the soil to fully dry out. Use a spray bottle to mist regularly.

With this care, Adiantum laevigatum spores will begin to germinate in 7-21 days after sowing. Tiny gametophytes will emerge first, followed by small ferns.

Storing Adiantum Laevigatum Seeds

Unused Adiantum laevigatum spores can be stored for later sowing. Follow proper storage methods to maintain viability:

• Allow seeds to fully dry out before storage.

• Place spores in an airtight container like a paper envelope or plastic bag. Glass jars also work well.

• Store in a cool, dry place away from direct light. The refrigerator is ideal at 40-50°F.

• Avoid freezing, as this can damage seeds. The freezer may be used for short term storage up to 3 months.

• Label containers with the seed type and date collected.

• In proper conditions, Adiantum laevigatum spores remain viable for 1-2 years before germination rates decline.

Sowing Adiantum Laevigatum Seeds

Once germinated, Adiantum laevigatum seedlings can be moved from the seed starting mix and sown into their permanent growing containers. Follow these tips:

• Wait until seedlings have 2-4 true leaves before transplanting. This allows roots to establish.

• Carefully separate seedlings using a fork, ensuring some soil remains around the roots.

• Gently transplant each seedling into a 3-4 inch pot filled with sandy potting soil amended with peat moss.

• Settle soil around the roots and water thoroughly after transplanting.

• Place in a bright, humid area out of direct sunlight. Maintain consistently moist soil.

• After 2-3 months, upgrade to a 6 inch pot. Larger planters can be used as the ferns continue growing.

With the proper germination, storage, and sowing techniques Adiantum laevigatum can be readily grown from its tiny seeds. Pay close attention to humidity, soil moisture, and lighting at all stages for the highest success rate. In no time you’ll have lush, graceful ferns to enhance your indoor or outdoor space.
