If the foliage of the fig tree suddenly turns yellow and falls off, this could have various causes. A virus or iron deficiency could be the cause. Too much moisture is partly responsible for both triggers, to which the fig reacts very sensitively.
Why is my fig tree getting yellow leaves?
Yellow leaves on the fig tree can be caused by fig mosaic virus or iron deficiency. Excess moisture promotes both problems. Reduce the amount of watering, avoid waterlogging, and repot the plant in fresh, loose soil.
The Fig Mosaic Virus
When infected with this virus, yellow leaf spots initially appear; as the disease progresses, the entire leaf turns yellow. The attractive lobes of the leaves show deformities. The virus is common in figs exposed to stress in wet and cool summers or excessive watering. If possible, reduce the amount of watering and avoid waterlogging in the future.
Leaf drop due to deficiency symptoms
The most common cause of yellowing leaves is a lack of nutrients, primarily iron deficiency. This is caused by waterlogging, soil compaction or a planter that is too small. Repot the fig in fresh, loose soil and reduce watering. It is sufficient to water the plant when the substrate on the top feels dry. Always pour away excess water in the saucer.
