Many Fiddle Leaf Fig owners eventually notice small, reddish spots on their plant’s leaves. While concerning, these are often a common and manageable issue. Understanding these spots is key to maintaining a healthy Fiddle Leaf Fig.
Identifying Red Spots
Red spots on Fiddle Leaf Fig leaves typically appear as tiny, pinpoint specks, reddish-brown or sometimes purplish. They are most commonly observed on new, unfurling leaves. As these leaves mature, the red spots often fade, becoming less noticeable. The spots do not usually spread or increase in size once the leaf has fully developed.
Common Causes of Red Spots
The most frequent cause of red spots on Fiddle Leaf Fig leaves is oedema. This occurs when the plant’s roots absorb more water than the leaves can transpire. Excess water creates pressure within the plant’s vascular system, causing tiny cells in the leaves to swell and burst. These ruptured cells then manifest as small, reddish-brown spots.
Oedema often results from inconsistent watering, such as allowing the soil to dry out significantly between waterings before providing a large amount. While oedema is the primary cause of distinct red spots on new growth, other issues can cause leaf discoloration. For instance, spider mites might cause tiny brown dots or stippling, but these usually come with other signs like webbing. Fungal or bacterial infections typically present as larger, irregular brown or black spots, or yellowing.
Resolving Red Spots and Prevention
Addressing red spots involves correcting watering habits. Provide consistent moisture without waterlogging the soil. Allow the top 2 to 4 inches of soil to dry out before watering thoroughly until water drains from the bottom of the pot. This ensures adequate moisture while preventing root suffocation. Using a well-draining potting mix and a pot with drainage holes is also important to avoid excess moisture around the roots.
During the growing season (typically spring through early fall), Fiddle Leaf Figs generally require more frequent watering than in the cooler winter months when their growth slows.
Long-Term Fiddle Leaf Fig Health
Promoting overall Fiddle Leaf Fig health contributes to its resilience and helps prevent issues like red spots. These plants thrive in environments that mimic their native tropical habitat. Bright, indirect light is ideal, such as near an east-facing window or a few feet from a south or west-facing window. Direct, harsh sunlight can lead to sunburn, manifesting as rust-colored or light brown spots.
Fiddle Leaf Figs appreciate consistent temperatures (60-80°F) and adequate humidity. Avoid cold drafts from windows or air vents, as sudden temperature fluctuations can stress the plant. Regularly cleaning the large leaves with a damp cloth helps remove dust, improving light absorption. Fertilizing with a balanced liquid fertilizer every 4 to 6 weeks during the growing season supports robust growth.
