How to Care for Your Ficus triangularis (Triangle Fig)

The Ficus triangularis, commonly known as Triangle Fig, is a refined indoor ficus species loved for its distinctive triangular leaves and light, airy branching. Its crisp geometric foliage gives it a modern, architectural look while still feeling soft and natural. With bright interior conditions, steady moisture rhythms, and consistency in placement, this species becomes a beautifully sculptural houseplant that adds texture and movement to curated spaces.

Light Requirements

• Prefers bright interior light with steady daily illumination
• Strong light maintains leaf density and prevents sparse growth
• Keep the plant in one consistent location to avoid stress and leaf drop

Watering Schedule

• Allow the soil to dry partially between waterings
• Drying speed varies with indoor temperature, airflow, and seasonal light
• Water slowly and evenly so the soil hydrates without becoming heavy
• Always check dryness below the surface using your finger or a moisture meter

How to Understand Watering Needs

• Triangle Fig prefers gentle cycles of partial dryness followed by even rehydration
• Leaves may soften slightly when fully dry
• Yellowing leaves often indicate watering too frequently
• A predictable rhythm of drying supports a healthy root system and a dense canopy

Fertilizer Tips

• Feed monthly during spring and summer with a balanced liquid fertilizer
• Pause feeding in fall and winter
• Light, consistent feeding encourages new leaf production and maintains vibrant color

Trimming and Pruning

• Prune to maintain shape or encourage branching
• Make clean cuts above a node to direct new growth
• Remove aging or damaged leaves as needed
• Occasional grooming keeps the plant light, airy, and refined

Pest Control and Identifying Issues

• Inspect regularly for spider mites, scale, and mealybugs
• Spider mites appear as tiny dots or fine webbing
• Scale looks like small round bumps attached to stems
• Mealybugs appear as white cottony clusters
• Treat pests with neem oil or insecticidal soap until resolved
• Keep foliage clean and maintain steady airflow to prevent reinfestation
• Early detection helps protect tender new leaves

Common Issues

• Leaf drop: Often occurs after relocation or sudden changes in conditions
• Yellowing leaves: Usually tied to watering too frequently
• Crispy edges: Can develop during extended dryness or low humidity
• Sparse or leggy growth: Indicates insufficient light

Repotting Notes

• Repot every one to two years, or when roots begin to fill the vessel
• Use a structured indoor potting mix with strong aeration
• Repot in spring so the plant can adjust during active growth

Lifespan and Growth

Ficus triangularis grows slowly, forming a delicate, branching structure accented by crisp, triangular leaves. With proper care and strong light, it becomes a long lived, sculptural houseplant that adds refined texture and modern elegance to bright interiors.
