How to grow

Cultivation

Grow indoors or under glass in a 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 soft water and apply a half-strength balanced liquid fertiliser monthly. Water sparingly in winter. Fronds can rot if they become too wet

Propagation

Sow spores are 21°C (70°F) as soon as ripe, but resulting plants are unlikely to come true. Separate rooted runners in late winter or early spring

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

Remove any dead fronds

Pests

Can suffer from scale insects
