Care Guide
Heart Fern Care Guide
Watering: This fern requires consistently moist soil. It does not possess a drought-tolerance mechanism; if the soil dries out completely, the fronds will quickly shrivel and may not recover. Water when the surface of the soil just begins to feel slightly less moist.
Light: Thrives in bright, indirect light. Avoid direct sunlight, which will scorch the heart-shaped leaves. It can tolerate medium light but growth will slow significantly.
Humidity: High humidity (60%+) is non-negotiable for this species. It is an ideal candidate for terrariums, glass cloches, or placement near a high-quality humidifier.
Temperature: Maintain a warm environment between 60°F and 85°F. Protect the plant from cold drafts, air conditioning vents, and heaters.
Soil & Potting: Use a moisture-retentive but well-draining mix, such as a combination of peat moss, perlite, and pine bark. Ensure the pot has drainage holes to prevent root rot.
Common Issues: Brittle, brown edges usually indicate low humidity. Yellowing leaves may suggest overwatering or waterlogged soil.
