Although Phnom Penh Daphne is a kind of ornamental flower, if we encounter Phnom Penh Daphne leaves turn yellow, we must not ignore, leaf yellowing is also a manifestation of unhealthy plants, the following pro-agricultural network to introduce Phnom Penh Daphne leaves yellowing is how, what are its reasons?
1. Incorrect soil acidity and alkalinity.
Phnom Penh Daphne likes to live in a relatively loose, fertile, humus-rich acidic soil. If the selected soil is alkaline, it will cause the leaves of Phnom Penh to turn yellow slowly.
Solution:
If you need to change the pH of the soil, you can go directly to the florist to buy acidic soil, and then transplant Phnom Penh Daphne into a new soil. If you don't want to transplant, you can also add sulfur to the current soil. Usually we choose ferrous sulfate solution, which can not only change the acidity and alkalinity of the soil, but also improve soil fertility, killing two birds with one stone.
The light is too strong
Daphne in Phnom Penh likes the sun, but is afraid of the hot sun. In summer, plants should be placed in a cool and ventilated environment, or in an environment without direct sunlight. If the sun shines too hard or there is no sunlight, it will cause the leaves to turn yellow.
Solution:
If the light is too strong, it is naturally necessary to move Phnom Penh to a cooler site, but because Phnom Penh Ruixiang can not be completely out of contact with the sun, it is best to move it to a place with sufficient astigmatism.
Third, the temperature is too low
The cold resistance of Phnom Penh Daphne is relatively poor, if the temperature is too low, the growth of the plant is inhibited, and the leaves are easy to yellowing and falling off.
Solution:
The cultivation of Phnom Penh Daphne in winter needs to be moved to the sunny place indoors in advance to ensure that the room temperature is more than 5 ℃ before Phnom Penh can safely survive the winter.

Solution:
If Phnom Penh Daphne has rotten roots, then the original soil can no longer be used, need to be replanted with clean sterilized culture soil, put in a cool and ventilated place, reasonable watering.
5. Improper fertilization
Phnom Penh Ruixiang likes fertilizer, especially mature organic fertilizer, but the amount should be good, fertilization should be diligent. If you fertilize too much and do not water in time, it is easy to cause fertilizer damage, resulting in Phnom Penh Daphne leaves yellowing.
Solution:
Should be diluted before fertilization, fertilizer can choose mature bean cake fertilizer water, while fertilization should be careful not to put fertilizer on the leaves.
VI. Diseases and insect pests
Phnom Penh Ruixiang improper maintenance is easy to be disturbed by diseases and insect pests, Fusarium wilt or leaf spot disease is, the leaves will be yellow and dry.
Solution:
During the onset of the disease, timely spraying, once a week, continuous spraying or root irrigation for 5 or 6 times, the effect will be more obvious. In addition, the smashed garlic can be buried in the soil, which can play a role in sterilization.
