Are Boston Ferns Hard to Care For?

Boston ferns (Nephrolepis exaltata) are a species of fern that is native to tropical and subtropical regions. They are popular houseplants and are known for their ability to thrive in shady, humid conditions. While Boston ferns can be finicky about their environment, they are generally not difficult to care for.

With proper care, these plants can live for many years. Here are some tips for caring for your Boston fern: Light: Boston ferns prefer indirect sunlight or filtered light.

They will tolerate low light levels, but may become leggy if they do not receive enough light. If your plant is looking pale or has yellow leaves, it may be getting too much sun. Water: Keeping your fern evenly moist is key to its health.

Allow the soil to dry out slightly between waterings, but never let it become completely dry. These plants like high humidity, so misting them with water on a regular basis will help keep them happy. You can also set the pot on a tray of pebbles and water to create a more humid environment around the plant.

Temperature: Boston ferns prefer temperatures between 60-75 degrees Fahrenheit (15-24 degrees Celsius). They cannot tolerate cold drafts or extreme heat, so make sure they are kept in a consistent environment. If possible, avoid placing them near heating or cooling vents where temperature fluctuations can occur.

Fertilizer: Feed your fern monthly during the growing season (spring and summer) with a balanced fertilizer diluted by half. Be sure to stop fertilizing in late summer or early fall so that the plant can begin its dormancy period. During this time, allow the soil to dry out completely before watering again.
