The Fiddle Leaf Fig (Ficus lyrata) is a tropical plant native to West Africa, where it thrives in warm, humid environments. As a houseplant, its temperature tolerance is crucial for maintaining health and growth. Understanding its ideal temperature range helps replicate its natural habitat and prevents stress-related issues like leaf drop or stunted growth.
The Fiddle Leaf Fig prefers a consistent temperature range of 65–75°F (18–24°C) during the day. At night, it can tolerate slightly cooler temperatures, but they should not drop below 60°F (15°C). This range mimics the warm, stable conditions of its native environment, promoting photosynthesis and metabolic processes without causing thermal stress.
3.1 Cold Stress: Temperatures below 50°F (10°C) can damage the plant, causing leaf discoloration (yellowing or browning), wilting, or even root rot due to slowed water uptake. Prolonged exposure to cold drafts or sudden drops can lead to irreversible harm.
3.2 Heat Stress: Above 85°F (29°C), the plant may exhibit curled leaves, dry edges, or accelerated water loss. High heat combined with low humidity exacerbates stress, as the plant struggles to regulate transpiration.
4.1 Winter Care: Avoid placing the plant near cold windows, heaters, or vents. Indoor heating can dry the air, so maintaining humidity (via misting or a humidifier) is essential.
4.2 Summer Care: Shield the plant from direct, scorching sunlight. Ensure adequate airflow to prevent heat buildup, but avoid strong drafts from air conditioning.
Fiddle Leaf Figs benefit from microclimate management. Grouping plants together can stabilize humidity and temperature, while thermal curtains or plant mats (for colder climates) help buffer against fluctuations. Always monitor room thermometers to ensure consistency.
6.1 Symptoms: Drooping leaves, brown spots, or slowed growth indicate stress. Cold damage often appears as blackened foliage, while heat stress causes crispy edges.
6.2 Solutions: Relocate the plant to a stable environment, prune damaged leaves, and adjust watering (less in cold, more in heat). Use a pebble tray or humidifier to moderate humidity.
When moving the plant (e.g., outdoors in summer), gradual acclimatization over 1–2 weeks prevents shock. Start by placing it in a shaded, sheltered spot and slowly introduce it to new conditions.
