Nephrolepis exaltata aka Boston Fern

Taxonomy

Nephrolepis exaltata, commonly known as the sword fern or Boston fern, is a species of evergreen, frost-tender fern native to the Americas. It belongs to the family Lomariopsidaceae, although it is sometimes classified in the families Davalliaceae or Oleandraceae, or in its own family, Nephrolepidaceae. This fern can grow up to 40-90 centimeters in height, and in some cases, even reach 1.5 meters. It is also referred to as the Boston swordfern, wild Boston fern, Boston Blue Bell Fern, tuber ladder fern, or fishbone fern. The fronds of this fern are lance-shaped and pinnate, initially growing upright before arching and drooping with age. One cultivar of Nephrolepis exaltata is the Variegated Boston Tiger Fern, which features stunning foliage variegation and is often grown in hanging baskets. This fern is easy to care for, requiring watering only when the soil is dry. The growth rate and leaf color of the Variegated Boston Tiger Fern may vary depending on factors such as soil type, sunlight, and temperature.

How to care for Boston Fern

Difficulty

Caring for Boston Fern is a breeze, as it is highly adaptable and forgiving to minor neglect.

Soil

Boston Fern is very sensitive to dry soil. To ensure your Boston Sword Fern is thriving and blooming, choose a potting soil that retains moisture. A good soil should still allow for adequate drainage and contain lots of organic matter. Coco coir or sphagnum moss are great soil additives that will help to retain moisture and provide your Boston Sword Fern with the nutrients it needs for healthy growth. Make sure to mix these soil additives into the potting soil before planting and water the soil thoroughly. By providing your Boston Fern with a well-draining, moisture-retaining soil, you can help to maximize its growth and keep it blooming.

Lighting

To ensure optimal growth, the Boston Fern prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Boston Fern to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.
