Identifying and Growing Fern Spores

Miss Kim demonstrates fern propagation at the Memphis-area master gardener Spring Fling 2019. She explains fern biology, focusing on sporophyte and gametophyte forms. The process involves collecting mature spores, preparing a sterile growing medium, and planting spores in a controlled environment. Care for young ferns includes gradual exposure to air and light. The entire process requires patience, as it can take up to a year for ferns to mature.

What is a key characteristic of ferns that distinguishes them from more advanced plants?

• They are non-vascular.

• They have a vascular system but no flowers or cones.

• They have cones.

• They have flowers.

What are the two basic forms of ferns?

• Leaf and Root

• Rhizome and Frond

How can you identify immature fern spores?

• They are brown.

• They are green.

• They are red.

• They are black.

What is the purpose of using an envelope in the spore collection process?

• To heat the spores.

• To fertilize the spores.

• To dry and dehisce the spores.

• To add moisture to the spores.

Why is it important to use a sterile seed mix for planting fern spores?

• To provide nutrients.

• To prevent contamination.

• To enhance growth speed.

• To add color to the soil.

What is the role of vermiculite in the planting medium?

• To increase temperature.

• To add color.

• To retain moisture.

• To provide nutrients.

What should you do after sowing the spores in the planting medium?

• Water them daily.

• Put the lid on and place in a well-lit room.

• Keep them in a dark room.

• Place them in direct sunlight.

What indicates that the fern spores are starting to germinate?

• The soil turns black.

• The container becomes warm.

• Condensation droplets form on the lid.

• The spores change color.

How long should you wait before checking on the germinating ferns?

• One week

• Two weeks

• One day

• One month

What is the final step in acclimating young ferns to outdoor conditions?

• Keep them covered at all times.

• Water them heavily.

• Gradually expose them to dry air and sunlight.

• Expose them to direct sunlight immediately.
