Light

Medium, indirect light. Direct sun yellows the fronds.

Water

Water when the top inch is dry. It handles a short dry spell better than most ferns, but don't make a habit of it.

Pot and soil

A peat- or coir-based mix with perlite and good drainage.

Pot it inRosy Houseplant Soil · 4 qtThe everyday peat-free mix. 4 qt repots 2–3 plants. Peat-free, by Rosy Soil

Feeding

Half-strength liquid fertilizer monthly in spring and summer.

Grooming

Cut tired or brown fronds at the base to make room for new ones.

Through the year

Spring and summer: feed lightly and keep the soil moist. Fall and winter: water a little less, stop feeding and keep it away from heat vents.

If something's off

Brown, crispy fronds mean dry soil or very dry air. Pet safety isn't established; keep it out of reach.

Plays well with

Plant it with friends.
