Taxonomic Information

Appearance

Cyclosorus ferns have fronds that can be either pinnate or bipinnate. The fronds are typically elongated, with a triangular or lanceolate shape. The fronds are also usually dark green in color and can grow up to 2-3 feet in length. The ferns produce spores on the undersides of their fronds, which are covered by small, round sori.

• Fertilization: Fertilize the ferns once a month during the growing season with a balanced fertilizer.
• Soil: Use a well-draining potting mix that is rich in organic matter.
• Sunlight: Cyclosorus ferns prefer bright, indirect light. Avoid direct sunlight, as it can scorch the fronds.
• Hardiness Zones: Cyclosorus ferns are hardy in USDA zones 9-11
