Nephrolepis exaltata, also known Boston fern is an easy-care fern with large leaves.

Boston fern originates from the humid forests of the southern United States and South America. Its green leaves can grow up to 2.5 meters long, which makes the plant form dense and decorative tufts. The leaves tend to hang downwards as they grow larger, and the plant is therefore often grown in hanging baskets.

Botanical description.

This fern, often called the Boston Fern , is one of the best plants for purifying indoor air. According to NASA research, it can filter harmful substances like xylene, toluene, and formaldehyde from the air. It also helps increase the humidity in the room, making it especially beneficial for people who suffer from dry skin or dry mucous membranes. And as an added bonus – it’s completely safe for both cats and dogs!

Care instructions

Nephrolepis exaltata is perfect for rooms with limited sunlight. It is excellent for homes and offices with low light. Keep the soil slightly moist and place the plant in a location with as much humidity as possible and indirect light. It tolerates morning or evening sun best, as it requires high humidity.

The fern prefers temperatures between 18–24°C. It cannot withstand extreme heat or cold. Temperatures above 35°C can damage the plant, as can frost.

Spear fern has a low nutrient requirement but still grows best in a nutrient-rich soil. For indoor cultivation, a weak dose of liquid plant nutrient is recommended once a month during spring and summer.
