Fig trees are a popular fruit tree for gardeners because of their delicious fruit and beautiful foliage. However, when the leaves of a fig tree start to turn yellow, it can be concerning and frustrating. In this article, we will explore some of the reasons why fig tree leaves turn yellow and what you can do to fix the problem.
Lack of Water
One of the most common reasons for yellowing leaves in fig trees is a lack of water. Fig trees need consistent moisture to thrive, especially during hot summer months. When the soil around the root system dries out, the leaves will start to turn yellow and eventually fall off.
If your fig tree is suffering from a lack of water, you can fix the problem by watering it more frequently. Make sure to water deeply, so that the water reaches the roots of the tree. You should also consider adding some mulch around the base of the tree to help retain moisture in the soil.
Nutrient Deficiencies
Yellowing leaves can also be a sign that your fig tree is lacking essential nutrients. Nutrient deficiencies can occur when the soil is not rich enough in certain minerals or if the tree’s roots are not absorbing enough nutrients.
To avoid nutrient deficiencies, make sure your fig tree is planted in nutrient-rich soil and fertilize it regularly with a balanced fertilizer. You should also consider adding organic matter to the soil, such as compost or aged manure, to improve soil quality.
Pests or Diseases
Yellowing leaves can also be a sign that your fig tree has been infested by pests or infected with a disease. Common pests that attack fig trees include spider mites, scale insects, and mealybugs. These pests can cause leaves to yellow and drop off prematurely.
Diseases such as fig rust or anthracnose can also cause yellowing leaves in fig trees. These diseases are caused by fungi and can be treated with fungicides.
To prevent pests and diseases from affecting your fig tree, make sure to regularly inspect the tree for signs of damage or infestation. You should also practice good hygiene by removing fallen leaves and debris from around the base of the tree.
Environmental Stress
Environmental stress can also cause yellowing leaves in fig trees. Stress factors such as extreme temperatures, high winds, or excessive sunlight can cause leaves to turn yellow and fall off.
To avoid environmental stress, make sure your fig tree is planted in a location that provides adequate shelter from harsh weather conditions. You should also consider using shade cloth or other forms of shading to protect your tree from excessive sunlight.
FAQ
How often should I water my fig tree?
Fig trees need consistent moisture to thrive, especially during hot summer months. Water your fig tree deeply once a week, or more frequently if you live in an area with hot, dry weather.

Fig trees require a balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium. You can use a granular fertilizer or a liquid fertilizer, applied according to the manufacturer’s instructions.
How do I know if my fig tree has pests or diseases?
Inspect your fig tree regularly for signs of damage or infestation. Look for spots on the leaves or bark, webbing, or tiny insects crawling on the leaves. If you suspect your tree has pests or diseases, contact a professional arborist for advice on how to treat the problem.
