Button Fern Care: Drought-Tolerant & Charming

Unique Appeal

Pellaea rotundifolia has arching fronds covered in small, round, leathery leaflets—like buttons on a string. New Zealand native, dependable, and unlike most ferns, tolerates drier conditions.

Care Essentials

• Light: Bright indirect. No direct sun.
• Water: Water thoroughly, then allow top inch to dry. Soggy soil kills it. Yellow/wilted fronds = overwatering.
• Humidity: Moderate to high.
• Temp: 60–75°F year-round. No dormancy.
• Soil: Peat-based + perlite/sand for drainage.
• Fertilizer: Monthly year-round, 20-20-10 at half strength.

Maintenance

• Repot in spring when root-bound; only 1 size up. Use drainage hole.
• Divide in spring with sharp knife—ensure roots with stems.
• Spores possible but slow/unreliable.

Watering tip: Always check soil before watering. This fern forgives dryness, not wet feet.
