Boston Fern Care Outdoors: Essential Temperature Considerations

The Boston fern (Nephrolepis exaltata) is a graceful and elegant fern native to tropical and subtropical regions. While it is commonly grown indoors as a houseplant, it can also thrive outdoors in warmer climates with the right care. One of the most important aspects of outdoor Boston fern care is providing it with the appropriate temperature range.

Ideal Temperature Range

Boston ferns prefer warm temperatures and will grow best in temperatures between 65-85°F (18-29°C). They are not tolerant of cold temperatures and will experience damage or die if exposed to temperatures below 45°F (7°C) for extended periods. If you live in a climate with cold winters, it is best to bring your Boston fern indoors during the winter months.

Protecting from Heat

While Boston ferns enjoy warm temperatures, they can be sensitive to extreme heat. In hot climates, it is important to provide them with some protection from the sun during the hottest part of the day. This can be done by placing them in a shady spot or providing them with shade cloth.

Avoiding Temperature Fluctuations

Boston ferns do not like sudden changes in temperature. When moving them outdoors, it is important to gradually introduce them to the new temperature over a period of a few days. This will help to prevent shock and damage to the plant.

Monitoring Temperature

To ensure your Boston fern is receiving the correct temperature, it is a good idea to monitor the temperature around the plant. You can use a thermometer or a temperature monitoring device to track the temperature and make adjustments as needed.

By following these temperature guidelines, you can help your Boston fern thrive outdoors. These beautiful ferns can add a touch of elegance and beauty to your outdoor space with proper care and attention.
