Reason: The leaves of Chunyu gradually turn yellow. One of the most important reasons is the lack of certain fertilizer elements, such as nitrogen, phosphorus, potassium, magnesium, iron, etc. Insufficient nutrients will naturally cause the leaves to turn yellow.In addition to the lack of nutrients, it may also be caused by excessive fertilization, which can also cause old leaves to yellow and fall off.
Solution: If there is a lack of fertilizer nutrients, it should be applied according to the growth needs to meet the needs of good plant growth.If fertilizer damage occurs, fertilization should be suspended and diluted by watering when fertilizer damage occurs.
Reason: If you do not water regularly during growth, the soil will become dry and lack water, causing the leaves to turn yellow.Once too much water is given at one time, it will make the roots unbearable, causing the roots to rot and the leaves to yellow.
Solution: In the state of drought, we must pay attention to reasonable watering, keep the pot soil moist state, so as to facilitate the growth of plants.Control the amount of watering, can not water too often, watering only need to irrigate thoroughly.
Cause: If grown in alkaline soil, it will retard growth and cause yellow leaves.
Solution: You can change the soil for the plants. If the soil is alkaline, you should water the rice.
Reason: If the growing environment is too closed and the light is too dark, it will cause the leaves of spring feathers to turn yellow.On the contrary, exposure to strong light can also cause yellow leaves.
Solution: Do not keep in a shaded environment for a long time. It is better to keep semi-shaded astigmatism.
