There are three main reasons for the yellow leaves of Thalia. If the light is too strong, the plant should be moved to a cool and ventilated place, and then sprayed with water on the leaves, so that the leaves can recover slowly. If it is caused by excessive fertilization, the situation is lighter, it is necessary to increase the amount of irrigation to dilute the concentration of fertilizer in the soil. If the situation is serious, new containers should be replaced immediately. If it is caused by too little watering, it is necessary to move the pot to the shade immediately and increase the amount of watering slowly.
