The leaflets are oblong in shape, with a pointed tip and a serrated edge. The fronds emerge from a central rosette and grow up to 1m tall. Pronephrium ferns are known for their graceful, airy appearance and are commonly used as accents in gardens and indoor spaces.
Care Guide
Pronephrium ferns are relatively low-maintenance plants that require moderate care to thrive. Here are some tips for caring for your Pronephrium fern:
Water: Pronephrium ferns prefer moist soil, but be careful not to overwater them. Water when the top inch of soil feels dry to the touch, and be sure to drain excess water from the saucer beneath the pot.
Fertilization: Pronephrium ferns benefit from a balanced, water-soluble fertilizer applied every two weeks during the growing season.
Soil: Pronephrium ferns prefer well-drained, slightly acidic soil. A mixture of peat moss, perlite, and sand works well.
Sunlight: Pronephrium ferns prefer bright, indirect light. Avoid direct sunlight, as it can scorch the delicate fronds.
Hardiness Zones: Pronephrium ferns are hardy in USDA zones 9-11.
