Soil discomfort, excessive soil viscosity or severe plates will cause dark spots on the polycutric blades, and need to be replaced in time to reintegrate the soil. The temperature is too low. It needs to be transferred to the warm indoor maintenance in time; the light is too strong, and the strong light exposure will also cause dark spots to produce multi -meat blades, and it needs to be transferred to a ventilated and cool environment in time.
1. Soil discomfort
Multisanial plants are suitable for loose and fertile, nutrients with sufficient nutrients. The condition of the soil will cause dark spots on the leaves. Person -changing treatment in time can be carried out to make the corrupted leaf soil and perlite into the substrate of cultivation, so that the fleshy root system can better breathe.
2. The temperature is too low
The fleshy plant has poor cold resistance, suitable for growing in a warm environment. Dark spots. Therefore, after the winter, the fleshy meat is needed to be transferred to the warm environment of the room in time, and the room temperature is controlled above 5 ° C. A layer of plastic bag can be kept on the succulent to keep warm.
3. Too strong light
Succulent plants are not resistant to strong light sun exposure. , Resulting in dark spots. Therefore, when maintainingin summer, shading measures need to be taken to give appropriate astigmatism to meet its growth needs.
4. Improper water and fertilizer
The demand for water and fertilizer during the growth of meat is greater. Dark spots are produced. Too much fertilization can also cause the leaves to be burned and blackened the leaves. Therefore, the amount of watering needs to be strictly controlled during daily maintenance, and the soil needs to be discharged in time after water accumulation. When too much fertilization, water should be poured into the pot soil to dilute the fertilizer.
