The Fiddle-Leaf Fig (Ficus lyrata) is a popular tropical plant prized for its large, glossy leaves and striking appearance. As a native to West African rainforests, it thrives in warm, humid environments. Understanding its temperature tolerance is crucial for maintaining its health and growth, especially when grown indoors or in non-native climates.
The Fiddle-Leaf Fig prefers a consistent temperature range of 60–85°F (15–29°C). This range mimics its natural habitat, where temperatures remain relatively stable year-round. Within this range, the plant can efficiently perform photosynthesis, absorb nutrients, and maintain cellular functions without stress.
Temperature fluctuations outside the ideal range can severely impact the plant:
Prolonged exposure to cold temperatures can cause leaf drop, stunted growth, and even root damage. The plant's cells may rupture due to freezing, leading to blackened or wilted foliage. Cold drafts from windows or air conditioning should be avoided.
Excessive heat accelerates transpiration, leading to dehydration and leaf scorch. High temperatures may also encourage pest infestations (e.g., spider mites) and reduce the plant's ability to retain moisture, even with adequate watering.
While the Fiddle-Leaf Fig prefers consistency, slight seasonal adjustments can be beneficial:
In colder months, ensure the plant is kept away from drafty windows or doors. Supplemental heating (like space heaters) should be used cautiously, as dry air can exacerbate humidity issues.
During hot periods, provide shade or relocate the plant to a cooler spot. Increased humidity (via misting or humidifiers) helps mitigate heat stress.
Humidity plays a complementary role in temperature tolerance. The Fiddle-Leaf Fig thrives in 40–60% humidity, which helps regulate moisture loss during temperature fluctuations. Low humidity combined with high heat can cause leaf edges to brown, while cold, dry air may lead to leaf cracking.
Sudden temperature shifts shock the plant. If relocating the Fiddle-Leaf Fig (e.g., moving outdoors in summer), gradually expose it to the new environment over 7–10 days to allow acclimatization. This reduces the risk of leaf drop or stress.
Monitor for these symptoms to adjust care promptly:
