First of all, excessive watering will cause the leaves of Fu Guizhu to turn yellow.

One of the most common reasons is that Fu Guizhu watered too much. The common symptoms are: the young leaves are dark yellow and dull, the old leaves have no obvious changes, and the new shoots have not shrunk. At this time, just take the flowers out of the pot, dry them in the shade, and then put them back in the pot.

Second, insufficient watering caused the leaves of Fu Guizhu to turn yellow.

The yellowing caused by insufficient watering of Fu Guizhu is completely different from that caused by insufficient water. The yellowing caused by water shortage is mainly manifested in the withering of the tip or edge of leaves, but the new leaves grow normally. At this time, you only need to water directly, but pay attention to watering thoroughly.

Third, strong sunlight caused the leaves of Fu Guizhu to turn yellow.

Fu Guizhu is a shade-loving plant. If there is strong light, it will also cause yellowing, which is manifested as the withering of the tip or edge. At this time, just move it to the shade.

Fourth, insufficient light caused the leaves of Fu Guizhu to turn yellow.

Plants can't grow without light. If bamboo leaves are hidden for a long time and cannot form chlorophyll, they will turn yellow and then fall off. At this time, just put it in the sun.

Fifth, excessive fertilization caused the leaves of Fu Guizhu to turn yellow.

This is a very common reason. Too much fertilization can easily lead to yellow flowers, mainly manifested in the dry and brown tops of new leaves, thick leaves, dull protrusions, brown old leaves and falling off. At this time, fertilization should be stopped immediately and washed with water.

Sixth, the lack of fertilizer caused the leaves of Fu Guizhu to turn yellow.

Insufficient fertilizer will cause insufficient nutrients, so insufficient fertilizer will also cause yellowing of leaves, mainly in the fact that the color of young leaves becomes pale, yellow or light green, not green; Old leaves generally don't see any big changes at this time. It's time to check the soil in the basin. If there is a dry knot, it will be changed. Pay attention to applying thin fertilizer frequently when applying fertilizer, and pour some alum water or Bika water-soluble fertilizer in time.

Seventh, it is adjacent to TV and refrigerator. Fu Guizhu's leaves turned yellow.

Fuguizhu is connected with TV, air conditioner and other electrical appliances, which is easy to cause yellowing of the leaf edge. At this time, as long as it is put away and put in the right place, it can grow well.

Eighth, improper plastic surgery caused Fu Guizhu's leaves to turn yellow.

Rich and precious bamboos tend to grow too vigorously, so when changing pots and adding soil, we should pay attention to pruning old and residual fibrous roots and redundant stems and leaves to avoid excessive consumption of nutrients and play a role in supporting roots and protecting leaves. If you don't pay attention to shaping, it is easy to cause the leaves to turn yellow.

Second, the causes of yellowing of hydroponic bamboo leaves and the corresponding treatment methods.

Compared with soil culture, hydroponics has most of the same reasons, but there are also some differences, mainly including:

First, the water quality impact

For hydroponics, water is the basis for the growth of Fugui bamboo, and naturally it is also an important aspect that causes the leaves to turn yellow. This time mainly depends on whether its root system is fresh. If it leads to root rot, it is necessary to cut off the rotten root system and use cold boiled water instead.

Second, the influence of light (here also includes two aspects)

A, the light is too dim: if you don't get enough sunlight, you can't form chlorophyll, and the leaves will naturally turn yellow.

B, the light is too strong: Fu Guizhu is not suitable for strong light irradiation, which will cause the leaves to turn yellow.

In view of the above two situations, the yellow leaves should be cut off first. At the same time, cut off the rotten roots and put them in an environment with suitable temperature and astigmatism, so that they can grow again.

Third, fertilization? Impact (here also mainly includes two aspects)

A. Too much fertilization: Too much fertilization can easily cause flowers to turn yellow, which mainly shows that the top of new leaves is dry and brown, the leaves are generally thick, dull, the protrusions are not stretched, and the old leaves are brown and fall off. Change the water again at this time.

B, lack of fertilizer: mainly manifested in the color of young leaves becoming lighter, yellow or light green, not green. Old leaves generally don't see any big changes at this time, just add a proper amount of Bika water-soluble fertilizer.

Fourth, adjacent to the TV, refrigerator, etc.

Just like soil culture, you just need to put it away and put it in a suitable place to grow well.

Fifth, improper plastic surgery.

Rich and precious bamboos tend to grow too vigorously, so when changing pots and adding soil, we should pay attention to pruning old and residual fibrous roots and redundant stems and leaves to avoid excessive consumption of nutrients and play the role of supporting roots and protecting leaves. If you don't pay attention to shaping, it is easy to cause the leaves to turn yellow.

Third, other matters needing attention when bamboo leaves turn yellow

Another reason why leaves turn yellow is iron deficiency. You can buy some ferrous sulfate and put it in water according to the instructions. The easiest way is to find two small nails and put them in the water (preferably rusty nails).
