How to grow

Cultivation

Grow indoors or under glass in a peat-free multipurpose compost or a mix of 1 part loam, 2 parts sharp sand and 3 parts leaf mould, in bright filtered light, with moderate to high humidity and good ventilation. During the growing season, water moderately with soft water and apply a half-strength balanced liquid fertiliser monthly. Water sparingly in winter. Fronds can rot if they become too wet. See how to grow ferns as houseplants for further advice

Propagation

Propagate by spores, sow spores at 21°C (70°F) as soon as ripe. Separate rooted runners in late winter or early spring

Suggested planting locations and garden types
  • Houseplants
  • Patio and container plants

Pruning

Pests

May be susceptible to scale insects

Diseases

Generally disease-free but may be susceptible to rot if fronds become too wet
