Long Leaf Fig (Ficus binnendijkii), also known as Ficus Alii, Alii Fig, Banana-Leaf Fig, and Narrow Leaf Fig, is a sleek indoor tree that grows best in bright filtered light and airy soil.

About Long Leaf Fig

Long Leaf Fig is a refined indoor tree grown for its long, narrow, glossy leaves and its calm, upright shape. Compared with broader-leaved ficus types, it has a lighter, more architectural look that suits bright interiors without feeling heavy or crowded.

The foliage creates a soft, fountain-like canopy, which helps the plant look elegant even when young. In strong filtered light, Long Leaf Fig stays fuller and more tailored, while in weaker light it becomes looser and more open as it stretches toward the brightest source.

One of its advantages indoors is that it usually responds well to simple consistency. In a stable spot with steady warmth, moderate watering, and good light, it often behaves more evenly than many people expect from a ficus, with less dramatic leaf drop than more sensitive indoor tree types.

How to Care for Long Leaf Fig

Watering

Keep watering moderate. Let the top 1–1.5 inches (2–4 cm) of the potting mix dry before watering again, then water thoroughly until excess drains away.

The goal is a steady cycle of moisture followed by enough drying for the roots to breathe. In winter or in lower light, extend the interval and let the soil dry more deeply, because cool wet soil often leads to yellowing leaves and root stress. If Long Leaf Fig starts shedding suddenly, check whether the mix is staying wet too long or whether the plant has recently faced a change in placement or temperature.

Sunlight

Long Leaf Fig grows best in medium light, meaning bright indirect or filtered light. A place near a bright window with softened sun usually gives the densest, most balanced canopy.

It can tolerate lower light, but growth becomes slower and the plant may thin out near the base. If you want to increase sun exposure, do it gradually over a week or two so the leaves can adjust without stress.

Temperature

Aim for moderate temperatures, around 64–77°F (18–25°C), with as few drafts as possible. Long Leaf Fig prefers stable indoor warmth rather than repeated shifts between cold and hot air.

Keep it away from cold winter glass, direct heater airflow, and strong air-conditioning blasts. Slightly cooler room temperatures are usually manageable if watering is reduced at the same time.

Humidity

Moderate humidity suits Long Leaf Fig well. It usually grows comfortably in average homes, though very dry indoor air can contribute to brown tips and slower growth.

If heating makes the air especially dry, grouped plants or a nearby humidifier can help. Even then, the potting mix should still be allowed to dry properly between waterings.

Soil

Use rich organic soil that also stays airy and fast-draining. Long Leaf Fig does best in a houseplant mix that feels nourishing but does not compact heavily around the roots.

A quality mix improved with perlite, pumice, or fine bark usually works well. Drainage holes are essential, and a slightly snug pot is often safer than an oversized container that stays wet for too long.

Feeding & Maintenance

Feed Long Leaf Fig lightly during active growth with a diluted balanced fertilizer about once a month. Reduce or pause feeding in winter when growth naturally slows.

Prune selectively to shape the plant and encourage branching where needed. Trimming longer shoots during the growing season often helps the canopy fill in more evenly. Wiping dust from the leaves from time to time also helps the plant make better use of available light.
