What to do about yellowing, withered leaves on a fiddle-leaf fig? Here are the right remedies

Soil alkalization
Soil alkalization is a problem that occurs in all indoor plant growing, because when we water our plants, most of us use tap water, and tap water is also known as hard water. Watering plants with hard water over a long period causes large amounts of salts to accumulate in the soil, which leads to yellowing and withered leaves.
Solution: For daily watering, you can use purified water. If that is not possible, you can let tap water sit for a few days in advance, or leave it in the sun for a few days, and then water with it. This avoids the problem of soil alkalization.
Improper fertilizing
During fertilizing, if the nutrients are not balanced and the amount of nitrogen fertilizer is too small or there is none at all, the plant will develop yellowing and withered leaves.
Solution: You can add more nitrogen fertilizer, but do not apply too much at one time. Apply a dilute fertilizer and increase the number of applications, so that the fertilizer will not harm the roots.
Unsuitable environment
If the plant has just moved to a new environment, its leaves easily turn yellow. In fact, when repotting a plant, the plant itself will develop various problems.
Solution: Just care for it according to normal maintenance methods, and at the same time, be careful not to let direct sunlight hit it.
Repotting
Unless there is a major reason, it is not recommended that friends repot their plants casually.
Pests and diseases
The appearance of pests and diseases can also cause its leaves to turn yellow and wither. So be sure to pay attention during daily care. And it is best to clean the potting soil regularly.
