The most likely problem encountered by families in flowering is the yellowing of leaves. Yellow leaves of flowers usually have the following reasons:
One is water yellow, that is, too much water to make the soil water long and wet, poor ventilation and even some root rot. The young leaves appear dark and dull and the new shoots shrink.
The second is fat yellow, which is more fat, showing the yellow leaves off the old leaves, although the new leaves are thick and shiny, but the general bump does not stretch. If it is a precious flower, it can be sprinkled with a layer of Chinese cabbage or radish seeds, then unplug it after a few days of emergence to consume nutrients.
The third is dry yellow, because the long-term no watering or dehydration, although the new leaf color is normal, but the lower leaves gradually dry yellow off aging.
Alkaline yellow is the fourth species, especially in southern China, where acidic soils are preferred, while in the northern part of the water, the leaves tend to fade, yellow, and even fall off. The easiest way is to pour the washed rice water or rainwater.
