Pteris cretica

Growing in Pots, Balconies & Indoors

The Cretan brake fern is one of the easiest indoor ferns and the grower confirms it as a houseplant. It thrives in bright shade in a pot indoors, on a shaded balcony, or in a bathroom, wanting steady moisture and no direct sun.

Quick Details

• Container Size: 5-12 L (1.3-3 gal); it stays compact
• Indoor Suitability: A good houseplant – easy in bright, indirect indoor light
• Best Spot: Full shade with light; bright indirect light, no direct sun
• Soil & Drainage: Rich, moisture-retentive but free-draining mix
• Watering in Pots: Keep evenly moist; average to plentiful, never bone-dry

Indoors & On the Windowsill

• A good houseplant: The grower confirms it – a reliable, forgiving fern indoors. Give it bright, indirect light and keep the mix lightly moist at all times.
• Humidity: It loves humid air; stand the pot on a damp pebble tray or grow it in a bathroom, and keep it away from hot, dry radiators.
• Windowsill growing: A shaded north or east sill is ideal; avoid hot, sunny glass that scorches the fronds.

On a Balcony or Patio

• Light & shade: Outdoors it needs a shaded, sheltered spot with no direct sun and shelter from drying wind. It is frost-tender, so bring it in for winter in cold areas.
• Practicalities: Compact and light to move; keep the soil moist as shaded pots still dry surprisingly fast in summer.

Choosing the Pot, Soil & Long-Term Care

• Pot & drainage: A 5-12 L pot with strong drainage holes and never leave it standing in a saucer of water, or the roots rot. Terracotta breathes and dries faster; glazed or plastic holds moisture longer.
• Potting mix: A well-aerated, organic-rich mix – potting compost, or peat/coir with perlite or vermiculite. It should hold moisture yet drain freely.
• Feeding: Feed lightly through the growing season; potted ferns need only a weak, regular feed.
• Repotting: Pot up or divide every couple of years once the roots fill the pot.
