Fig plants are a popular addition to gardens and indoor spaces due to their unique shape, gorgeous leaves, and delicious fruit. However, when the leaves of your fig plant start turning yellow, it can be a sign that something is amiss.

Yellowing leaves on a fig plant can indicate a range of issues, including overwatering, nutrient deficiencies, fungal diseases, pest infestations, and environmental stress. In this article, we will explore the possible causes of yellowing fig leaves and how to treat them.

Causes of Yellowing Fig Leaves

Overwatering

One of the most common causes of yellowing fig leaves is overwatering. When the soil around your fig plant is constantly wet, it can lead to root rot and deprive the plant of oxygen leading to yellow leaves. Overwatering can also cause the plant’s roots to suffocate and die, preventing the plant from absorbing nutrients properly.

To prevent overwatering, make sure that your fig plant is in well-draining soil, and only water it when the top inch or two of soil feels dry to the touch. It’s also essential to ensure that your pot or container has drainage holes to allow excess water to drain out.

Nutrient Deficiencies

Another possible cause of yellowing fig leaves is nutrient deficiencies. Figs require a well-balanced diet of nutrients such as nitrogen, phosphorus, potassium, magnesium, and calcium to grow correctly. A lack of any of these nutrients can cause yellowing or browning of leaves.

To prevent nutrient deficiencies in your fig plant, ensure that you fertilize it regularly with a balanced fertilizer designed for fruit trees. Additionally, adding organic matter such as compost or aged manure can provide additional nutrients.

Fungal Diseases

Fungal diseases such as leaf spot and rust can cause yellowing leaves on your fig plant. These diseases often start as small spots on leaves and progress to larger patches, causing the leaves to yellow, curl, and fall off.

To prevent fungal diseases, avoid overhead watering, which can spread fungal spores to other parts of the plant. Ensure that your fig plant is in a well-ventilated area with plenty of sunlight and space between other plants. If you notice any signs of fungal disease, remove the affected leaves and treat the plant with a fungicide.

Pest Infestations

Pests such as spider mites, scale insects, and mealybugs can cause yellowing of fig leaves by sucking on the plant’s sap. These pests can also cause the leaves to curl or develop a sticky residue.

To prevent pest infestations, examine your fig plant regularly for signs of infestation. If you notice any pests, remove them by hand or treat the plant with an insecticidal soap or oil spray.

Environmental Stress

Environmental stressors such as extreme temperatures, low humidity, and inadequate light can cause yellowing of fig leaves. Inadequate light can cause the plant to drop its leaves or grow weak stems leading to yellowing.

To prevent environmental stress on your fig plant, ensure that it is in a location with adequate light and temperatures between 60-85°F. Additionally, maintain humidity levels of at least 50% around your plant.

How To Treat Yellowing Fig Leaves

The treatment for yellowing fig leaves depends on the underlying cause. Here are some general tips to help revive your fig plant:

  • Watering: If overwatering is the problem, reduce watering frequency and ensure that the soil is well-draining.
  • Nutrition: If nutrient deficiency is causing yellowing leaves, fertilize your fig plant with a balanced fertilizer designed for fruit trees.
  • Fungal Diseases: Remove affected leaves and treat the plant with a fungicide.
  • Pest Infestations: Remove pests by hand or treat the plant with an insecticidal soap or oil spray.
  • Environmental Stress: Move your fig plant to a location with adequate light and temperature, or increase humidity levels.
