Alii Fig / Banana-Leaf Fig / Ficus binnendijkii
Ficus maclellandii
description
The Alii Fig (Ficus maclellandii), also called Banana-Leaf Fig, is a slender indoor tree with long, narrow, glossy leaves that arch softly from upright branches. Its airy, willow-like silhouette sets it apart from broad-leaved fiddle-leaf and rubber figs. The plant is often sold as Ficus binnendijkii, reflecting a long-running botanical naming mix-up around this closely related fig.
How to care for Alii Fig
sunlight
In nature, this fig grows in bright, open woodland and filtered forest light. Place it near a bright window at home, with gentle sun if it is introduced gradually.
Bright indirect light
This is the best starting point. Set it within a few feet of an unobstructed east or bright north window, or slightly back from a south or west window. Sparse new growth and small leaves suggest it needs more light.
Gentle direct sun
Morning or late-day sun can suit an acclimated plant. Introduce it over a week or two, and filter strong midday sun to prevent pale, crispy patches on the leaves.
watering
Water thoroughly when the top 2-5 cm of soil feels dry, then let excess drain fully. Alii Figs prefer evenly moist soil, but sitting in water quickly reduces root health.
Spring and summer
As a starting point, water about every 7-14 days. Check the soil first, since bright light, warmth, low humidity, a small pot, or a fast-draining mix can shorten the interval.
Autumn and winter
With cooler temperatures or lower light, watering may be roughly every 2-3 weeks. Wait until the top 2-5 cm is dry and the pot feels noticeably lighter, but do not let the entire root ball stay dry for long.
humidity
Preferred humidity
Alii Fig comes from warm, humid regions, but it usually adapts well to average homes. Aim for 50-60% relative humidity, with 40-60% generally acceptable. Very dry air, especially near heating vents, can cause brown crispy leaf edges, curling, or premature leaf drop.
Acceptable household range
- For a lasting increase, run a room humidifier near the plant.
- Grouping plants together can provide a modest boost, but leave space for good airflow.
temperature
Preferred range
Approx. winter minimum
Native to warm, frost-free regions of Asia, the Alii Fig prefers steady indoor warmth. Cold drafts and sudden temperature changes can cause leaf drop, while typical indoor heat is usually tolerated.
nutrition
March - August
Feed about once a month while the plant is actively growing, using a balanced liquid houseplant fertilizer diluted to half the label strength. Skip feeding in darker, slower months unless it is still producing healthy new growth.
Nitrogen
Nitrogen supports the Alii Fig's long, glossy leaves and steady new growth. A balanced fertilizer supplies enough, so avoid extra feeding if growth is weak from low light or poor watering.
Potassium
Potassium supports overall vigor and helps the plant handle normal indoor stresses. Regular, moderate feeding provides it without needing a separate supplement.
soil
Light, well-draining soil
Use a loose, airy mix that holds some moisture without staying soggy. Combine about two parts quality potting soil with one part perlite or pumice and one part fine bark to support the Alii Fig's roots.
pH 6,0 - 6,8
This is mildly acidic to nearly neutral. A standard houseplant mix usually works; choose one labelled for indoor plants and avoid heavily limed mixes.
