Blue Star Fern Care Guide

Blue Star Fern

Phlebodium aureum

Blue Star Ferns have soft blue green fronds and fuzzy golden rhizomes. They tolerate slightly drier soil than many common indoor ferns, making them a relatively manageable fern for the home.

Light

Provide medium to bright indirect light. Blue Star Ferns can tolerate lower light, but growth may become slower and less full. Avoid strong direct sunlight, which can scorch the fronds.

Water

Water when the top inch of soil feels dry. Thoroughly moisten the soil and allow excess water to drain.

Do not keep the soil constantly saturated, but do not allow it to remain completely dry for an extended period.

Humidity

Moderate to high humidity is preferred. A humidifier is more effective than frequent misting. Provide good airflow around the foliage.

Temperature

Keep between approximately 60 and 80°F. Protect the plant from cold drafts, heating vents, and sudden temperature changes.

Soil and Repotting

Use a loose, organic, well draining potting mix. A blend containing indoor potting soil, orchid bark, and perlite works well.

Keep the fuzzy golden rhizomes at or slightly above the soil surface. Burying them can cause rot.

Fertilizer

Feed monthly during spring and summer with a balanced houseplant fertilizer diluted to half strength. Reduce feeding during fall and winter.

Common Problems

Brown, crispy fronds usually indicate dry soil, low humidity, or excessive sunlight.

Yellow fronds may indicate overwatering or poor drainage.

Watch for scale, mealybugs, and spider mites.

Pet Safety

Blue Star Ferns are generally considered pet friendly. However, pets should still be discouraged from chewing houseplants because any plant material may cause digestive upset.

Mary Mae’s Quick Advice

Give your Blue Star Fern filtered light, let the top inch of soil dry, and never bury its fuzzy golden rhizomes.
