How do you take care of a heart fern?

Answered by Jason Smith

To take care of a heart fern, there are a few key factors to consider. Let’s dive into each aspect and discuss the best practices for ensuring the health and well-being of your heart fern.

Lighting: Heart ferns thrive in bright, indirect light. This means placing them near a window where they can receive ample light, but not direct sunlight. Direct sun can scorch the delicate fronds of the fern, so it’s best to provide them with a dappled morning light or filtered light throughout the day. If you notice the leaves turning yellow or brown, it may be a sign that the fern is receiving too much direct light, and you should consider moving it to a slightly shadier spot.

Humidity: Heart ferns are native to tropical regions and, as such, require high humidity to thrive. One way to provide them with the necessary humidity is by misting the foliage with water daily. This mimics the natural conditions they would experience in their natural habitat. Alternatively, you can place the fern in a bathroom or a terrarium where the humidity levels are naturally higher. Another option is to use a humidifier in the room where the fern is located to maintain the ideal humidity levels.

Watering: Heart ferns prefer consistently moist soil, but they don’t like to sit in waterlogged conditions. It’s important to strike a balance between keeping the soil moist and avoiding overwatering. Before watering, check the top inch of soil with your finger. If it feels dry, it’s time to water. When watering, make sure to thoroughly saturate the soil, allowing excess water to drain out of the pot. Avoid letting the plant sit in standing water, as this can lead to root rot.

Temperature: Heart ferns prefer temperatures between 60°F and 75°F (15°C to 24°C). They can tolerate slightly cooler temperatures, but it’s important to keep them away from drafts or sudden temperature fluctuations, as they can cause stress to the plant. Avoid placing the fern near heaters, air conditioning vents, or open windows during cold spells.

Fertilizing: Heart ferns benefit from regular feeding during the growing season (spring and summer). Use a balanced, water-soluble fertilizer diluted to half strength and apply it every two to four weeks. Be sure to follow the instructions on the fertilizer packaging for the appropriate dilution ratio and application method. During the dormant period (fall and winter), it’s best to reduce or eliminate fertilization.

Pruning: Pruning is not usually necessary for heart ferns unless you want to maintain a certain shape or remove any dead or damaged fronds. If you notice any yellow or brown leaves, carefully trim them off at the base using clean, sharp scissors or pruning shears. This will promote a tidy appearance and allow the plant to focus its energy on healthy growth.

Propagation: Heart ferns can be propagated through division. To do this, carefully remove the fern from its pot and gently separate the root clumps into smaller sections, making sure each section has a good amount of roots and foliage. Plant the divisions in separate pots with well-draining soil, and provide the same care as you would for a mature heart fern.

Heart ferns thrive in bright, indirect light and require humidity to stay healthy. Mist them daily or keep them in a humid environment like a bathroom. Keep the soil consistently moist, but avoid overwatering. Maintain temperatures between 60°F and 75°F and fertilize regularly during the growing season. Prune only as needed and propagate through division when desired. By following these care tips, you can enjoy the beauty of a healthy and vibrant heart fern in your home or garden.
