Why do the leaves turn yellow

As with many other representatives of monocotyledonous plants, the development of dieffenbachia is accompanied by the formation of new leaves at the top of the shoot and the gradual death of the lower ones with the baring of the trunk. Therefore, the lower leaves already in the second year of life of the plant begin to turn yellow, dry up and fall off — this is a natural process. But if the apical leaves also began to turn yellow, then this is most likely due to improper care or damage to the plant by pests.
