Fern, for the record
The very first ferns may have appeared as early as the Primary Age, around 500 million years ago! More than thousand varieties exist all over the world, a multiplicity of shapes and colors.
Ferns do not produce flowers, and their leaves sprout directly from the rhizome, that swollen, woody underground stem often confused with the root.
In reality, roots are fine fibrous filaments, called adventitious roots, since they start from a stem. Coiled up on themselves, the young fronds resemble the end of a violin neck.
Planting the fern
Plant the ferns in spring or fall, in partial shade or shade, in cool soil, preferably rich in humus and drained. Pure heather soil is very suitable, as is forest soil.
The natural presence of ferns indicates a soil rich in humus and which retains moisture well.
Do not bury the stump too deeply, the upper part must be touching the level of the ground, otherwise it may rot.
In a container, provide a well-drained mixture of heather soil or peaty soil.
Maintain soil freshness throughout the growing season with regular mulching and watering. Spray in the evening after a strong heat. On the pruning side, just cut the dry fronds at the end of winter to clean the clumps properly.
Watch out for slugs: if they have nothing more tender to bite into, they are likely to feast on the young fronds in the spring.
To multiply, divide the clump at the end of the season. Be careful not to damage the roots, which are very fragile.
Tips about ferns
Coarsely grind the fronds of dry ferns you cut and use them as mulch for chilly plants or as shade for young seedlings.
Avoid ferns in your compost : they decompose very slowly.
