Scale fern - Asplenium ceterach (Care, Characteristics, Distribution, Images)

Scale fern

Also known as: Arabian ceterach, Rusty-back fern, Common spleenwort

Rusty back earned its name because it has brown hairs on the undersides of its leaves. Scale fern is perhaps best known for its capabilities as a recovery plant. This is an adaptation to extreme droughts where the plant can dry out almost totally, appearing dead, and then recover completely when it becomes wet again.

Water: Scale fern thrives in moist environments similar to its rocky European origins, with a preference for stable humidity. Recommended watering is twice weekly. Commonly grown indoors, scale fern is an evergreen with consistent water needs year-round, making it a resilient indoor garden choice.

Fertilize: Fertilize scale fern with high nitrogen monthly during the growing season using a diluted quarter-strength solution; avoid winter feeding. Young scale ferns require consistent nourishment, while mature plants need less. Always water before fertilizing to prevent root burn, enhancing scale fern's vitality and longevity.

Pruning: Scale fern requires minimal pruning, primarily dead frond removal and cutting back overgrowth. Early spring is ideal for pruning to support new growth, enhance health, and prevent disease. Gentle techniques are essential, promoting a lush appearance and maintaining shape for aesthetic appeal in gardens.

Propagation: Scale fern grows best in well-draining soil, replicating its natural habitat. Consistent moisture without waterlogging is crucial for germination. Gradual acclimatization aids scale fern in adapting to drier environments, enhancing resilience. Careful handling of young ferns is necessary due to their sensitivity in early growth stages.
