Solution: We need to strengthen the water spraying on its pages or the space around the ground to alleviate it. In addition, you can cover it with a plastic bag, but this is not conducive to ventilation. So we need to cut more holes in the whole plastic bag, otherwise the internal temperature of the plastic bag will be too high under good lighting conditions, which will aggravate the yellowing and wilting of the leaves.
2. Overwatering leads to root rot: When we overwater smoothly, it will affect the normal respiration of plant roots. Once there is water in the basin, it will cause difficulty or unsmooth breathing at the root, which will lead to root rot and yellow and black leaves.
Solution: Clean up the accumulated water in the basin and add a small amount of slightly wet fine soil. If it is maintained indoors, it will take 3-5 days to water once when the indoor temperature exceeds 20 degrees Celsius. Pay attention to the situation in the basin when watering to avoid water accumulation in the basin.
3. Insufficient soil nutrients in the basin: As we all know, plants usually get nutrients from the soil. After a long time, the nutrients in the soil will naturally become less and less. If no measures are taken to supplement nutrients in time, the plants in the basin will lack nutritional supplement. In the long run, it will lead to the yellowing of leaves due to lack of nutrition, which is particularly prone to the phenomenon of yellowing leaves.
Solution: As we said above, the lack of nutrients in the soil can easily lead to the smooth leaves turning yellow, so in view of this situation, we should increase nutrients for it in time. We can solve it by changing the soil. It is suggested that you buy humus soil, peat soil or multi-element soil with high nutrition to increase nutrients for your successful potted plant and avoid yellowing of leaves due to long-term lack of fertilizer.
4. Inappropriate lighting: Smooth places like light, especially in winter, which requires a good lighting environment. When the sun is too strong, it should be properly shaded and not exposed to the sun. Especially in summer, due to the change of the surrounding environment, if the light is not suitable, it is easy to cause the leaves to wilt and yellow, and even lead to death in serious cases.
Solution: Proper lighting is very important for the smooth planting of potted plants at home. It is recommended to put Shunxiu in a bright place indoors all year round and only accept astigmatism.
5. Inappropriate temperature: Under normal circumstances, it is easier to control the growth temperature smoothly. This situation is generally not easy to happen, but if the ambient temperature around potted plants exceeds 5℃-35℃, it is easy to have yellow leaves.
Solution: When the temperature is too low, especially when the temperature is below 5℃ in winter, it should be placed in a warm place indoors. When the weather is clear, give it enough light, which will not only help it spit green, but also help it spend the winter. When the temperature is higher than 35℃ in summer, shading measures should be taken or maintained in a cool and dark place.
6. Incorrect fertilization: If any plant is not fertilized correctly in the process of reproduction, its leaves will turn yellow, and of course, smooth potted plants are no exception.
Solution: In order to apply fertilizer smoothly, it is necessary to apply appropriate amount of thin fertilizer as much as possible, and it is forbidden to apply thick fertilizer or raw fertilizer, otherwise it will easily lead to yellow leaves and affect its growth. Moreover, after applying a certain amount of solid fertilizer, it must be watered, preferably with clear water. However, Bian Xiao suggested that it is best to use "Woye water-soluble fertilizer" instead of solid fertilizer and clear water, which can effectively prevent fertilizer damage and make the growth flourish smoothly.
7. Insect pests: Insect pests are the natural enemies of most potted plants. If the plants in the pot are eroded by pests such as mites, the smooth leaves will wilt, lose luster and turn yellow.
Solution: In view of the situation that potted plants in the plain are attacked by mites, acaricide spray, such as dicofol, nisolone, pyridaben and other drugs, can achieve good acaricidal effect.
