Hart's-Tongue Fern (Asplenium scolopendrium)

Hart's-tongue Fern requires consistently moist soil, especially during active growth. Water thoroughly when the top 2-3 cm of soil feels dry, but avoid overwatering, which can lead to root rot. Reduce frequency slightly in winter, allowing the surface to dry out a bit more between waterings. Ensure good drainage to prevent waterlogging.

Pruning for Hart's-tongue Fern is generally minimal and focused on maintaining plant health and aesthetics. Regularly inspect the plant and remove any yellowed, brown, or damaged fronds by cutting them cleanly at the base with sharp, sterilized scissors or pruners. This encourages new, healthy growth and prevents potential disease. Dead fronds can be removed at any time of year as they appear, keeping the plant tidy.

Propagation is primarily by spores, which can be challenging for home growers. Division of established clumps in spring is a more practical method. Carefully separate rhizomes, ensuring each section has roots and fronds, then repot. Ensure high humidity for newly divided plants to aid establishment.

Repot Hart's-tongue Fern every 2-3 years, or when it becomes root-bound, typically in spring. Choose a pot only slightly larger than the previous one. Use a fresh, well-draining potting mix rich in organic matter. Handle the delicate root ball gently to minimize stress.
