Ficus benjamina, commonly known as the Weeping Fig, is a popular ornamental tree prized for its graceful form, glossy green leaves, and adaptability. Native to Southeast Asia and northern Australia, it thrives in tropical and subtropical regions.
Ficus Benjamina Indoor and Outdoor Care
Whether grown indoors as a houseplant or outdoors in suitable climates, Ficus benjamina requires attentive care to remain healthy and lush.
In this in-depth guide, I will cover everything you need to know about growing this plant successfully in both environments.
I. Indoor Care Guide
Light Requirements
Ficus benjamina grows best in bright, indirect light. Ideally, place it near an east- or west-facing window where it receives filtered sunlight.
Direct midday sun through glass can scorch the leaves, while too little light causes slow growth and leaf drop.
In rooms with insufficient natural light, supplement with fluorescent or LED grow lights placed about 12 inches above the plant for 12–14 hours per day.
Avoid frequent relocation of the plant, as changes in light exposure often lead to leaf drop. Once acclimated to a light level, Ficus benjamina dislikes changes.
Watering Needs
Allow the top 1–2 inches of soil to dry out before watering. Use your finger to test moisture or a moisture meter for accuracy.
Water approximately once per week during the growing season (spring through fall), and every 10–14 days in winter. Water deeply until it drains from the bottom.
Soggy soil leads to root rot. Ensure pots have drainage holes, and remove any standing water from saucers.
Dry, crispy leaf edges, wilting, and leaf drop are signs the plant needs more water.
Humidity and Temperature
Weeping Fig prefers 40%–60 % humidity. In dry indoor air, use a humidifier, mist the leaves daily, or place the pot on a pebble tray filled with water (without submerging the base).
Ideal temperatures are 65°F to 75°F (18°C to 24°C). Protect from temperatures below 55°F (13°C).
Keep away from drafts, heaters, and air conditioners. Sudden temperature shifts can trigger leaf shedding.
Soil and Potting
Use a well-aerated, fast-draining potting mix. A good mix includes 2 parts peat moss or coco coir, 1 part perlite, and 1 part pine bark.
Choose a pot that is 1–2 inches larger in diameter than the root ball and has ample drainage holes. Clay or terracotta pots are preferred for their breathability.
Repot every 2–3 years or when roots outgrow the pot. Use fresh soil to rejuvenate nutrients.
Fertilization
Use a balanced liquid fertilizer (10-10-10 or 20-20-20) diluted to half strength. Feed every 4 weeks during active growth (spring to early fall). Reduce to once every 6–8 weeks in late fall and winter.
Compost tea, fish emulsion, or worm castings are gentle organic options. Yellowing leaves may signal nutrient deficiency; burned leaf edges can indicate over-fertilization.
Pruning and Shaping
Prune in late winter or early spring before new growth begins. This prevents shock and encourages a fuller canopy. Use clean, sharp pruning shears to prevent disease.
Pinch back tips to encourage branching. Remove leggy growth, dead wood, and inward-growing branches. For ornamental appeal, shape into a tree form or a braided trunk.
Repotting
Signs that your plant needs repotting include roots circling the pot, poor drainage, slowed growth, or toppling.
How to Repot:
- Water the plant 24 hours before repotting to reduce stress.
- Gently remove the plant, untangle roots, and prune damaged ones.
- Place in a larger pot with fresh soil and firm gently.
- Water thoroughly and keep in indirect light for a few days to recover.
Pests and Diseases
Watch for spider mites (fine webbing), scale (bumps on stems), mealybugs (cottony masses), and fungus gnats.
To treat, isolate infected plants. Wipe pests off with alcohol, or apply neem oil or insecticidal soap weekly until cleared.
Overwatering can cause root rot. Leaf spots may result from bacterial or fungal infections. Increase air circulation and avoid wetting leaves.
Troubleshooting Indoor Problems
Leaf Drop: Caused by environmental stress, such as sudden light changes, drafts, or overwatering. Allow the plant to acclimate before making changes.
Yellow Leaves: Often indicate excess moisture or nutrient imbalance.
Sticky Residue: Honeydew from pests like scale or aphids can attract sooty mold.
II. Outdoor Care Guide
Climate Suitability
Ficus benjamina is hardy in USDA zones 10–12. In cooler climates, it must be grown in containers and brought indoors during winter.
Prefers warm climates year-round. Prolonged exposure to temperatures below 40°F (4°C) can damage foliage. Thrives in humid outdoor conditions typical of tropical or subtropical regions.
Planting Location
Partial shade or filtered sunlight is ideal. Avoid intense direct afternoon sun, which can burn the leaves.
Choose a sheltered location to prevent wind damage to its flexible branches and delicate leaves. It can be grown as a specimen tree, privacy hedge, or espalier against a wall.
Soil Preparation
The ideal soil should be loamy, well-draining soil with good organic content. Aim for a pH of 6.0–7.0.
Incorporate compost, aged manure, or leaf mold to enrich soil and improve structure. Poorly drained soil increases root rot risk. Consider raised beds or mounded planting sites if drainage is poor.
Watering and Irrigation
Establishment Phase: Water deeply every 3–4 days for the first few months after planting.
Mature Plants: Once established, reduce watering to weekly. Increase frequency during drought or extreme heat.
Apply 2–3 inches of mulch to conserve moisture, regulate temperature, and suppress weeds. Keep mulch away from the trunk.
Feeding and Soil Care
Apply slow-release granular fertilizer in early spring and mid-summer. Use a balanced or nitrogen-rich formula.
Top-dress with compost or apply organic liquid fertilizers monthly during the growing season. Conduct soil tests annually to adjust pH and nutrient levels as needed.
Pruning and Shaping
Prune annually to control height and width, especially in urban or small garden settings. Maintain as a single-trunk tree or multi-stemmed shrub. For hedges, shear lightly multiple times per season.
Disinfect tools, make clean cuts above nodes, and remove no more than one-third of the plant at a time.
Cold Protection
Cover with frost cloths or burlap when temperatures dip below 40°F (4°C). Move indoors or into a greenhouse before the first frost.
Signs of frost Damage include blackened, curled leaves and soft stems. My advice is to prune after the risk of frost passes to encourage recovery.
Outdoor Pests and Diseases
Aphids, whiteflies, nematodes, and scale insects are common. Encourage beneficial insects and spray with horticultural oil.
Also, watch out for sooty mold (resulting from pest honeydew), leaf spot fungi, and crown gall. Remove infected material and sanitize tools.
Promote airflow, avoid overhead watering, and maintain plant vigor through proper nutrition and watering to prevent disease attacks.
Propagation Methods
Stem Cuttings
- Take 4–6-inch semi-hardwood cuttings in spring or early summer.
- Remove lower leaves, dip in rooting hormone, and plant in moist potting mix.
- Cover with a plastic dome or bag to maintain humidity. Place in bright, indirect light.
- Roots form in 4–8 weeks.
Air Layering
- Select a healthy branch and remove a ring of bark.
- Apply rooting hormone, wrap in damp sphagnum moss, and cover with plastic wrap.
- Secure with ties and check weekly. Roots should form in 6–8 weeks.
- Once rooted, cut below the root zone and pot separately.
Propagation Tips for Success
- Propagate during the active growing season.
- Keep humidity high and avoid disturbing cuttings until roots form.
- Use sterile tools to prevent infection.
Ficus Benjamina as a Bonsai
Ficus benjamina has small leaves, flexible branches, and strong root systems that make it ideal for bonsai training.
Use a shallow bonsai pot with free-draining bonsai soil. Prune roots and shoots regularly. Use wire to shape branches carefully, as Ficus bark is thin.
Keep the soil evenly moist. Feed every 2 weeks with diluted fertilizer during growth periods. For indoor bonsai, provide bright light and humidity. Rotate regularly for even growth.
Weeping Fig Toxicity and Safety
Ficus benjamina is toxic to cats, dogs, and humans if ingested. It contains ficin and ficusin, which can cause vomiting and irritation.
The milky latex sap can cause skin irritation in sensitive individuals. Wear gloves when pruning. Keep the plant out of reach of pets and children.
