What if the leaves of indoor potted plants turn yellow?

1, too much watering, the pot soil is too wet for a long time, resulting in soil hypoxia, local fibrous roots rot, hindering normal breathing and absorption of water and nutrients, leading to yellowing and loose leaves. After suffering, the young leaves turn pale yellow first, and then the old leaves turn yellow slowly. Immediately control watering, suspend fertilization and loosen the soil frequently to make the soil well ventilated.

2. Drought and dehydration. If the flowers are watered for a long time or watered halfway (that is, the upper part is wet and the lower part is dry), it will affect the nutrient absorption and easily cause the leaves to droop. First, the lower old leaves are aging and gradually wither and wither from bottom to top. At this time, it is necessary to water a little, spray some water, let it gradually recover, and then turn to normal watering.

3. Long-term fertilization. Long-term failure to apply ammonia fertilizer or change pots and soil will lead to the lack of nutrients such as nitrogen in the soil, resulting in weak branches and leaves, thinning and yellowing. It is necessary to dump the pots in time and replace them with new loose and fertile cultivation soil, and gradually increase the application of dilute decomposed liquid fertilizer or compound flower fertilizer.

4. Overfertilization. Too much fertilization will make the new leaves thick and uneven, and the old leaves brown and scattered. Therefore, fertilization should be stopped immediately, and the amount of watering should be increased to make the fertilizer flow out from the drainage hole at the bottom of the basin, or the basin should be emptied immediately, and the clods should be washed with water, and then replanted in the basin.

5, hot and high temperature. In summer, if cool flowers (such as cyclamen persicum, upside-down golden bell, begonia all the year round, etc.) are placed in a place with high temperature and directly exposed to strong light, it is easy to cause the tips and edges of young leaves to scorch, or the leaves will become yellow and loose. It needs to be moved to a well-ventilated shade in time.
