Dwarf Tree Fern

Taxonomic Name: Blechnum gibbum

Blechnum Family

Nonflowering Woody Plant

When most people think of ferns, they think of low, trunkless plants that occupy shady spots in the forest or garden. In fact, some tropical and subtropical ferns grow to tree size--a reminder of the time some 300 million years ago when tall-growing ferns were lords of the plant kingdom. The dwarf tree fern of modern times occupies an intermediate status between such giants and its shorter, extant relatives. At first, this species somewhat resembles a Boston fern, but as it continues to grow it develops a small trunk and attains a height of about five feet. The result is an attractive and unusual plant that resembles a palm tree in miniature.

How to Care for Your Plant:

LIGHT: Bright indirect sunlight is best; your dwarf tree fern will enjoy living in an unobstructed northern or eastern window. Your plant may also tolerate bright artificial lighting, at least for a few weeks.

WATERING: Water as soon as the soil surface feels dry to the touch. At least a little water should come out of the pot's bottom drainage holes, but the plant should not stand in saucer water for more than thirty minutes.  

FEEDING: Feed the plant only when it is actively growing, and then do so sparingly. Use an all purpose houseplant fertilizer applied at half the concentration and frequency listed in the product directions.

SPECIAL CONSIDERATIONS: Like almost all ferns, dwarf tree ferns need high humidity. Put a water-filled gravel tray or humidity tray under your plant, or place the plant near a room humidifier.
