The Fiddle Leaf Fig (Ficus lyrata) is a popular indoor houseplant, known for its large, violin-shaped leaves. Originating from West African rainforests, it is sensitive to environmental changes, especially temperature fluctuations. Understanding its specific needs is important for maintaining its health and vibrant appearance.
Ideal Temperature Range for Fiddle Leaf Figs
Fiddle Leaf Figs thrive in consistent, warm temperatures that mimic their native tropical habitat. The optimal daytime range is generally 65°F to 75°F (18°C to 24°C). At night, a slight dip to 55°F to 65°F (12°C to 18°C) is acceptable. Maintaining this consistent range is important because sudden temperature shifts can cause stress. Consistent temperatures support robust growth and healthy foliage. Place the plant in a stable location, away from drafts or direct heat sources, to prevent stress and leaf drop.
Minimum Temperature Tolerance
Fiddle Leaf Figs are sensitive to cold. The lowest temperature they can endure before significant damage is typically around 50°F (10°C). Temperatures falling below this threshold, even for short periods, can be harmful. Prolonged exposure to temperatures near this minimum, or sudden cold drafts, can be particularly damaging. Below 50°F, the plant’s physiological functions slow, and cells can sustain damage. Consistent exposure to cool conditions will progressively weaken the plant, making it more susceptible to other issues and hindering its overall health.
Signs of Cold Damage
When a Fiddle Leaf Fig experiences cold exposure, it displays several visual symptoms. Leaf discoloration is common, with dark brown or black spots often starting at the edges and spreading inward. Entire leaves can turn black and become crispy. Sudden leaf drop is another indicator, where the plant sheds numerous leaves rapidly. Stems might also feel mushy or soft. The plant may appear wilted or droopy, even if soil moisture is adequate.
Protecting Your Fiddle Leaf Fig from Cold
To prevent cold damage, position your Fiddle Leaf Fig away from drafty areas like frequently opened doors, cold windows, or heating and cooling vents. Insulate windows or use draft stoppers to minimize cold air infiltration. If indoor temperatures are consistently low, a small space heater can help maintain warmth nearby, but ensure it is not too close to dry out the plant. Maintaining consistent humidity (ideally 30-65%) also supports the plant’s resilience, as dry indoor air can exacerbate cold stress.
Recovering a Cold-Damaged Fiddle Leaf Fig
If your Fiddle Leaf Fig has sustained cold damage, move it to a warmer, stable environment away from cold drafts. Assess the damage by examining leaves and stems; trim away any leaves over 50% damaged or showing signs of rot, using clean, sharp scissors. Adjust watering by allowing the top few inches of soil to dry completely before watering again, as cold-damaged plants are prone to root rot. Avoid fertilizing immediately after cold damage, as the plant is already stressed. Provide consistent bright, indirect light; recovery can take time, sometimes several months for new growth to appear.
