1. Improper wateringIf there is too much water, or if you water too frequently, the soil will remain wet for a long time, causing water accumulation. The roots will easily rot, affecting its breathing and hindering its absorption of nutrients, so its leaves will turn yellow and fall off. At this time, you should help it drain the water, and pay attention to watering it appropriately in the future, not too much. 2. Improper fertilizationIf you fertilize it only once in a long time or don't change the pot or soil for a long time, the nutrients in the soil will have been absorbed by it, and there will be no new nutrients to supply it. Its branches will grow very thin, and its leaves will become thin and yellow. At this time, it is necessary to add fertilizer and change the soil in time. If there is too much fertilizer, it is not good. Its leaves will become thick and rough, and gradually turn yellow and fall off. At this time, you should immediately stop adding fertilizer, change the soil, wash the roots with water, and plant them in the new soil. 3. Temperature discomfortIf your home is in the north and the winter is extremely cold, even indoors it will be very cold and its leaves will die and fall off. If the home is very hot in the summer, the water evaporates quickly, and the roots do not provide nutrients in time, so the leaves will wither and fall off. So it is necessary to maintain a good temperature to ensure its normal growth. 4. Unsuitable soilThe salt and alkali content in the soil and water in many places in the north is higher, and the soluble iron in the soil is relatively lacking, so the leaves will turn green and fall off. At this time we need to change the soil. 5. Improper lightingIf you put it in an inappropriate place for a long time like the friend at the beginning of the article, expose it to excessive sunlight or never give it any light and put it in a dark area, it will become very weak, the leaves will not grow as usual and will fall off. 6. Insect and disease erosionIf it is attacked by pathogens, such as leaf spot disease, its leaves will easily die. If it is mosaic virus, yellow spots will grow on its leaves. If it is attacked by insects, such as scale insects and red spider mites, the leaves will fade or shrink and fall off. At this time, you need to buy special medicine for it. The ratio of medicine should be small and the ratio of water should be large, and spray it several times. |
