1、 Raise the temperature

Reason: Desert Rose is a plant that doesn't like cold. If the temperature in winter is relatively low, it may frostbite the plant and cause the leaves to turn yellow and fall

Solution: the South can take warm measures and put them in the open air for maintenance, but in the north, it must be moved indoors in time, and the temperature should be kept above 10 degrees, so that the frostbitten plants can gradually slow down

2、 Exposure to sunlight

Reason: Desert Rose is a kind of sun loving plant. It needs sufficient sunlight during its growth. If it is placed in a dark and shaded environment for a long time, its leaves will turn yellow and fall out if it is not exposed to the sun

Solution: if you find that desert roses lack light and turn yellow, move them to a place with good sunshine in time and expose them to light for at least 4 hours a day

3、 Adjust water and fertilizer

Reason: this kind of plant is not resistant to moisture and barren. If it is watered and fertilized too much during the maintenance process, it will lead to root rot, affect the normal transportation function, and cause leaf problems in the long run

solution: remove the plant, check if it is rotten, remove the rotten part, and adjust the water and fertilizer. p>

4、 Pest control

Reason: in the process of maintenance, if the plant is infected with diseases and pests, it will cause the leaves to turn yellow and fall down

Solution: cut off the sick branches and leaves of desert rose, strengthen ventilation and spray medicine in time
