The best way to grow ferns is through division, in spring time. Before you begin to divide your fern, ensure that the medium in which it is growing is moist a day or two beforehand.

When dividing the fern, make sure that it is gently dug up. Cut it apart into 2 or 3 clumps. The clump must include a piece of the rhizome and a growing tip from which the fronds will grow. Plant these in a sandy, well-drained medium and keep the medium moist for a few days, until the fern shows signs of new growth.

Ferns do not flower but they can be reproduced sexually from spores. Before sowing the spores, the medium in which the spores are sown, is to be sterilized. This can be done using boiling water. This ensures that fungal spores do not germinate and crowd out the fern being grown.

Peat moss is a good medium to use for germination of ferns. Once spores have been sown, the container needs to be covered with plastic (or glass), allowing for some air space above the medium and sown spores. Keep the germinating spores in a lightly shaded area at a temperature of 20ºC.

Germination can take up to 6 weeks, at which point it will look like a moss growing on the medium. Once the prothalli are well-developed, they can be pricked out into a small container with finely sifted soil, but the container must be covered with plastic or glass, until fronds begin to appear. These developing ferns must be kept in light shade.

Later when potting over, these plantlets need to be potted into a coarser textured, well-drained medium.
