Description for Nephrolepis acuminata
Nephrolepis exaltata has 50–250cm (20-98 inch) long and 6–15cm (2-6 inch) broad in tufted clusters arising from underground rhizomes. The individual pinnae (leflets) are as much as 2 to 8cm (1-3 inch) long and shallowly toothed, but not further divided. The pinnate vein pattern is also visible on these highly compound leaves. The round sori (clusters of spore-bearing organs) are in two rows near the margins on the underside of the pinnae.
The fronds grow upright at first, then arch gracefully downwards. They grow in lovely arching rosette shaped and spread by runners.

Planting and care
They make good houseplants, but require bright, filtered light and humid air.
Propagate from runners between late winter and early spring. Of the common cultivated ferns, the Boston fern is the most tolerant to drought. The fern thrives best in humid conditions, so when grown as a house plant it becomes necessary to mist the plant when relative humidity falls below around 80%.
| Sunlight | Soil | Water | Temperature | Fertilizer |
|---|---|---|---|---|
| Sun to Partial Shade, Light Shade | Does best with well-draining soils that are kept moist and humus-rich. pH range 5.6 to 6.0 (acidic), 6.1 to 6.5 (mildly acidic), 6.6 to 7.5 (neutral) | In summer Nephrolepis exaltata will need lots of water and frequent misting. As long as room temperatures remains above 13°C (55°F), water the plant plentifully as often as necessary to keep the potting mixture thoroughly moist. Do not allow the potting mixture to dry out. In winter this fern will need less water. If the temperature drops below 13°C (55°F) for more than a day or two, allow the top third of the potting mixture to dry out completely between waterings. | Normal room temperatures are suitable throughout the year. Minimum tolerable temperature is 10°C (50°F). For Nephrolepis exaltata grown at temperatures above 21°C (70°F) increase humidity by standing the pot on a tray of damp pebbles and mist-spraying the foliage daily. Nephrolepis exaltata may appear totally dead due to frost, it will re-emerge in the spring. |
Implement a half-strength, balanced liquid fertilizer on a monthly basis during growth. |
Caring for Nephrolepis acuminata
-
- Nephrolepis exaltata is one of the easiest of the ferns to grow indoors. These ferns need pliantly of space to develop their long fronds. Rotate the plant from time to time to ensure symmetrical growth, but as far as possible leave it undisturbed.
- In some of the extremely feathery forms of Nephrolepis exaltata Bostoniensis some of the fronds of the plant occasionally revers to the original species. Cut out any long, insufficiently segmented fronds as soon as they appear. If permitted to survive, they will take over the plant.Nephrolepis exaltata ferns do not tolerate dry air. They need high level of humidity provided by regular misting and trays of moist pebbles placed under their pots. Use trepid soft water if possible. Once a week, apply a gentle shower with trepid water. Leave them in bath to drain before returning them to their usual place.
