A Ficus can drop leaves when the light intensity is too low or after a displacement. Especially after purchasing in winter, the plant loses its leaves. In this case, do not water more than usual! Too much water can also lead to leaf loss. When there is a lot of leaf loss, it is recommended to place the plant a little closer to the window. Especially in the spring, the growth period of the Ficus, the plant will recover completely with good care.
A single yellow leaf is not a cause for alarm at all. If several leaves turn yellow and this also happens over a longer period, this can be a sign of exhaustion. In this case, it is recommended to additionally feed the plant.
Brown leaves can indicate too much or too little water. The reaction of the plant in both cases is the same, because the roots close. Therefore, carefully check the ground to find out which scenario applies.
