The Heart fern loves bright, indirect light. Do not place it in direct sunlight, as this can cause its delicate fronds to burn. If the plant is grown in too much shade, it may become leggy and lose its compact shape.


The Heart fern appreciates a well-draining soil mix that is rich in organic matter. A mix of peat moss and perlite or vermiculite is perfect. You should keep the soil consistently moist but not waterlogged.


The Heart fern needs regular watering to keep its soil moist but not waterlogged. You should water the plant when the top 2-3 inches of the soil is dry to the touch.

Avoid letting the soil dry out completely, as this can cause the plant to wilt. The plant may need more frequent watering in hot, drier conditions.


The Heart fern prefers temperatures between 60-75°F or 15-24°C. It can tolerate slightly cooler temperatures, but you should protect the plant from frost and cold drafts.

Humidity Level

Heart fern prefers high humidity levels of 50 percent or more. If the air in your home is dry, you can consider placing the plant on a tray of pebbles filled with water to increase humidity levels around the plant.

Alternatively, you can use a humidifier to increase the humidity in the room. Additionally, you can place the plant in your kitchen or bathroom, as these places are more humid.

Heart Fern Care



Any regular fertilization routine with a balanced, water-soluble fertilizer can help your heart fern. Fertilize Heart fern once a month during the growing season and then cut back fertilization in the fall and winter.

Be sure to dilute the feed to half the strength to avoid burning the delicate roots of the plant.


Heart fern does not need regular pruning, but you can remove any dead or damaged parts to keep the plant looking tidy. Make sure to use clean, sharp scissors or pruning shears to avoid damaging the plant.

Pests and Diseases

The Heart fern is usually pest and disease resistant, but it can be prone to spider mites and mealybugs. Watch out for any signs of infestation, such as webbing or tiny white bugs, and treat the plant with insecticidal soap or neem oil if necessary.

Overwatering can lead to root rot, so let the soil dry out slightly between waterings to rule out this issue.
