Banyan trees need sufficient light during their growth. If it is left in a dark place for a long time, plants can't carry out photosynthesis, which will lead to poor growth and thus lead to leaf shedding. Usually put it in the sun and shine all day, but in summer, it should be properly shaded to avoid sunburn.
Second, the temperature is too low.
Ficus alba is not cold-tolerant. When the temperature is lower than 15, it will enter the dormant state. If you want to spend the winter safely, you must ensure that the temperature is above 5, otherwise the leaves will easily fall off after frostbite. Be sure to keep warm in winter, move to a warm place indoors in advance, or cover the upper part with plastic bags to prevent colds.
Third, water shortage.
White banyan likes humidity. If there is no water during the growth process, the leaves of plants will dry up and fall off. In addition to regular watering, it is also necessary to properly spray water on its leaves, which can not only improve the humidity, but also clean the dust on the leaves and increase its ornamental value. It should be noted that there should be no water in the basin soil, otherwise it will lead to root rot.
Fourth, excessive fertilization.
If the banyan tree is fertilized too much, the thick fertilizer will burn the roots of the plant and cause the leaves to fall off. In view of this situation, it is necessary to remove the flowerpot immediately, take the plants out of the flowerpot, remove the old soil at the roots, cut off the rotten parts with sterilized scissors, and replant the flowerpot after the wound is dry.
