Fiddle leaf figs are popular houseplants, but many owners encounter a common issue: burnt-looking leaves. This guide explains why your fiddle leaf fig’s leaves might appear burnt, how to address the problem, and steps to prevent it from reoccurring.
Recognizing Burnt Fiddle Leaf Fig Leaves
Identifying burnt fiddle leaf fig leaves involves observing specific visual cues. You will typically notice brown or black patches forming on the foliage. These discolored areas often begin at the edges or tips of the leaves and can appear crispy to the touch. The burnt spots might also spread inwards, sometimes accompanied by a yellow ring around the affected area.
Understanding Why Fiddle Leaf Fig Leaves Burn
Several environmental factors can contribute to the burnt appearance of fiddle leaf fig leaves.
Too Much Direct Sunlight
Fiddle leaf figs thrive in bright, indirect light. When exposed to intense, unfiltered direct sunlight, their leaves can quickly scorch. This overexposure causes the plant’s chlorophyll to break down, resulting in bleached or light brown spots that often feel crispy.
Underwatering
Insufficient water supply leads to dehydration. When a fiddle leaf fig does not receive enough moisture, the leaves, especially the edges and tips, begin to dry out and turn brown, becoming brittle. This browning can spread inward. Severe underwatering can also cause the leaves to droop significantly.
Low Humidity
Fiddle leaf figs originate from tropical rainforests, where humidity levels are consistently high. In dry indoor environments, leaves can lose water too quickly through transpiration. This moisture loss often manifests as crispy brown edges or tips on the leaves.
Temperature Extremes
Sudden temperature fluctuations or prolonged exposure to excessively hot or cold conditions can harm fiddle leaf fig leaves. Temperatures below 60°F or above 85°F can stress the plant, causing browning. Proximity to heating vents, air conditioners, or drafty windows can also lead to localized temperature extremes, resulting in burnt spots or leaf drop.
Chemical Burn
Applying certain chemicals incorrectly can result in a burnt appearance on leaves. Over-fertilization can lead to a buildup of salts in the soil, burning roots and causing browning on leaf edges or tips. Certain pest control sprays, like undiluted neem oil, can also cause chemical burns if applied in strong concentrations or under direct sunlight.
Remedies for Burnt Fiddle Leaf Fig Leaves
Once fiddle leaf fig leaves show signs of burning, take immediate action to support the plant’s recovery.
Pruning Damaged Leaves
Removing damaged leaves helps redirect the plant’s energy towards new growth. Use clean, sharp pruning shears to make a clean cut at the base of the affected leaf. If a leaf is more than 50% brown, it is beneficial to remove it, as it will not recover its green appearance.
Adjusting Light Exposure
If sunburn is suspected, immediately move the fiddle leaf fig to a location with bright, indirect light. A spot a few feet from a south or west-facing window, or near an east or north-facing window, often provides suitable filtered light. Sheer curtains can also diffuse intense sunlight, protecting the foliage from further scorching.
Correcting Watering Habits
Water the plant thoroughly when the top 1-2 inches of soil feel dry, allowing excess water to drain completely from the pot. Consistent, deep watering ensures the root ball is adequately moistened.
Increasing Humidity
To counteract dry air, raise local humidity levels around the plant. Placing a pebble tray filled with water beneath the pot, ensuring the pot does not sit directly in the water, allows for gentle evaporation. Using a humidifier nearby or grouping plants can also create a more humid microclimate.
Addressing Temperature Issues
Relocate the plant away from sources of extreme temperature fluctuations. Keep it clear of drafty windows, exterior doors, and heating or air conditioning vents. Maintaining a stable room temperature (60°F-85°F) helps prevent thermal stress.
Preventing Burnt Fiddle Leaf Fig Leaves
Proactive care strategies are essential to avoid future leaf burning and maintain your fiddle leaf fig’s health.
Optimal Light Placement
Position your fiddle leaf fig in a spot that consistently receives bright, indirect light. East-facing windows are often ideal, providing gentle morning sun, while south or west-facing windows may require sheer curtains to filter intense afternoon rays. Avoid prolonged direct sunlight.
Consistent Watering Schedule
Water based on soil moisture, not a fixed schedule. Allow the top 1 to 2 inches of soil to dry before watering thoroughly until water drains from the bottom. This prevents both underwatering and overwatering.
Maintaining Adequate Humidity
Maintain humidity around your fiddle leaf fig consistently between 40% and 60%. In drier climates or seasons, use a room humidifier. Grouping plants can also increase humidity.
Protecting from Temperature Swings
Maintain a stable indoor temperature for your fiddle leaf fig (60°F-85°F), avoiding sudden drops or spikes. Place the plant away from cold drafts from windows or doors, and steer clear of direct airflow from heating or cooling vents.
Careful Fertilization and Pest Control
Always dilute fertilizer according to package instructions to prevent chemical burn. For pest control, use appropriate, diluted solutions and avoid applying treatments, especially oil-based ones like neem oil, in direct sunlight. Always test new products on a small, inconspicuous area first.
