1. It’s one of the most common problems with fiddles, so there are a lot of various reasons why the leaves become yellowish. First of all, it might point that there is not enough sunlight. Ideally, you should place the fiddle where it can get indirect diffused bright light.
2. Paradoxically, not only lack of sunlight but too much of it also can be harmful, because fiddle can get a sunburn. That’s another reason why its leaves can change the color to yellow. By the way, sunburn is easy to notice because only the top leaves will be damaged by the sun. The worst part is that you should cut off the injured leaves because they won’t recover. Thus, it is better to prevent the issue and not place your fig in direct sunlight.
3. Also, yellow leaves indicate that the plant is overwatered. If the leaves are getting yellow and wilt, but the tissue itself is limp and soft, the fig is overwatered. Keep in mind that this is a tropical plant, so you should water it only when the top inches of soil are completely dry.
4. Pay attention to the soil itself because it can also cause leaves to turn yellowish when it’s acidic. So take care of the state of the soil and use an adequate amount of fertilizers as lack of them is the final reason for the change of color.
