How to Care for a Heart Fern

use these instructions to care for a Heart Fern. this guide will tell you how to water your Heart Fern, its light, temperature, and humidity preferences; and any additional care your plant might need to help it grow.


Your Heart Fern will thrive in medium to bright indirect light.


Keep the soil moist but not soggy. If the soil dries and the leaves start to wilt, allow the plant to soak in the sink or bathtub in 1”-2” of water (without the saucer) for about 45-60 minutes.  Drain the sink and allow the Heart Fern time to expel all the excess liquid. Never let water collect in the saucer.


Your Heart Fern will appreciate a bit of extra humidity. Throughout the dryer times of the year, use a pebble tray and mist regularly.


The ideal temperature for your Heart Fern is between 60-85 degrees. If the temperature falls below 55 degrees, it will stop growing. Avoid cold drafts and direct airflow from heating and cooling vents.


Use a general-purpose liquid houseplant fertilizer diluted to half the recommended strength once every month during the spring and summer. There is no need to feed your plant in the winter when growth naturally slows. Before applying any form of fertilizer, make sure the soil is damp. Never apply fertilizer to dry soil.  


Your Heart Fern will tolerate water straight from the tap but would prefer filtered water. If you don’t have a filtration system, simply filling your watering vessel and leaving it out overnight will evaporate most harsh chemicals found in tap water.  


Heart Ferns are non-poisonous to humans and pets.
