The Fiddle Leaf Fig (Ficus lyrata) is a tropical plant native to West Africa, where it thrives in warm, humid environments. To replicate its natural habitat, maintaining an optimal temperature range is crucial for its growth and health. Temperature affects photosynthesis, transpiration, and overall metabolic processes, making it a key factor in care.
The Fiddle Leaf Fig prefers temperatures between 65°F (18°C) and 75°F (24°C) during the day. At night, it can tolerate slightly cooler temperatures, ideally no lower than 55°F (13°C). This range mimics its native tropical climate, ensuring steady growth and preventing stress. Temperatures outside this range may lead to leaf drop, stunted growth, or susceptibility to pests.
Exposure to temperatures below 50°F (10°C) can cause cold damage, manifesting as brown spots, wilting, or leaf loss. Conversely, temperatures above 85°F (29°C) may lead to dehydration, scorched leaves, or increased vulnerability to spider mites. Sudden temperature fluctuations, such as drafts from heaters or air conditioners, can also shock the plant.
In winter, protect the Fiddle Leaf Fig from cold drafts near windows or doors. If indoor temperatures drop significantly, consider using a space heater (placed at a safe distance) to maintain warmth. During summer, avoid placing the plant near direct, hot sunlight or air vents. A consistent environment is key to avoiding stress.
High humidity (around 40-60%) complements the Fiddle Leaf Fig's temperature needs. In dry or heated indoor environments, use a humidifier or mist the leaves to prevent moisture loss. Low humidity combined with high temperatures can accelerate water loss, leading to crispy leaf edges.
Watch for drooping, yellowing, or browning leaves, which indicate temperature-related stress. Cold stress often causes dark, mushy spots, while heat stress leads to dry, curled edges. Adjust the plant's location or room temperature promptly if these symptoms appear.
Use a digital thermometer to monitor room temperature near the plant. Keep the Fiddle Leaf Fig away from radiators, fireplaces, or cold windowsills. In transitional seasons, gradually acclimate the plant to temperature changes to avoid shock. Grouping plants together can also help stabilize microclimates.
