- Make sure you use a clean, sharp blade or gardening scissors to reduce the risk of infection.
Propagation of Woodwardia radicans (L.) J. Sm.
Woodwardia radicans, commonly known as the Americana chain fern, is a fern plant that is found in wetlands, swamps, and along the banks of streams and rivers. The plant has a creeping rhizome that develops slender, green fronds that can grow up to six feet tall. Propagation of Woodwardia radicans can be done by spores and divisions.
Propagation by spores
Propagation by spores is a simple and effective method to propagate Woodwardia radicans. The spores are produced in spore cases on the undersides of the fronds and are best collected when they turn brown. The following steps can be followed to propagate Woodwardia radicans using spores:
- Collect spores from the undersides of mature fronds when they turn brown and fall onto a paper
- Let the spores dry and store them in an airtight container
- Fill a seed tray with a sterile mix of peat moss, vermiculite, and sand
- Sow the spores evenly on the surface, pressing them gently into the soil mix
- Cover the seed tray with a plastic wrap to retain moisture and place it in a warm, bright area, such as a greenhouse or an east-facing window
- Keep the soil moist by misting with water and removing the plastic wrap occasionally for ventilation
- Transplant the young ferns to individual pots when they are large enough to handle
Propagation by division
Propagation by division is the most common method to propagate Woodwardia radicans. The rhizomes of the plant can be divided to create new clumps. The following steps can be followed to propagate Woodwardia radicans using division:
- Choose a mature plant with healthy, green fronds and adequate rhizomes
- Carefully dig the plant out of the ground or remove it from its pot
- Gently shake off the soil to expose the rhizomes
- With a sharp, sterilized knife, divide the rhizomes into sections, ensuring each section has fronds and roots
- Plant the divided sections in separate pots filled with a mix of peat moss, vermiculite, and sand
- Water the pots thoroughly and place them in a shaded area for a few days to allow the ferns to adjust to their new environment
- Move the ferns to a brighter location after a few days and keep the soil moist
Propagation of Woodwardia radicans by spores and division can be a great way to expand your collection of these beautiful ferns. With proper care and maintenance, the propagated plants can grow into mature, healthy, and attractive specimens.
