How to care for osmanthus better
The core content of this article: how to care for osmanthus better and the small knowledge of osmanthus cultivation skills, let's take a look together.
If the leaves of osmanthus turn yellow, it is necessary to take countermeasures according to the cause: if it is caused by inappropriate temperature, it should be given appropriate temperature; if it is due to excessive watering, it should reduce watering and not water until the soil is dry; if it is due to insufficient fertilizer or excessive fertilization, it should be fertilized reasonably; if the soil quality is not suitable, it should be appropriately changed.
I. Appropriate temperature
15-28℃ is the optimal temperature for the growth of osmanthus. In summer, if the temperature is too high and no cooling measures are taken or it is still exposed to the sun, it is easy for the leaves to turn yellow. In winter, if the temperature is too low and no appropriate measures are taken to keep warm, it will also cause the leaves to turn yellow. Therefore, when caring for osmanthus, attention should be paid to cooling in summer and it can be placed in a relatively cool place, while attention should be paid to keeping warm in winter and it can be moved indoors.
II. Reasonable watering
This flower is not tolerant to waterlogging. Once too much water is poured, it easily leads to root rot, which will cause yellow leaves. Therefore, when planting this plant, it is necessary to choose loose soil with good drainage. Also, do not water too frequently or too much at a time, and water only after the pot soil is dry.
III. Correct fertilization
If there is insufficient fertilizer, it will cause the plant to have yellow leaves. Therefore, during its growing period, we should apply fertilizer reasonably, both liquid fertilizer and compound fertilizer can be used, but the concentration of the fertilizer should not be too high. Also, we should change the pot and soil in time to ensure that the soil is not compacted and there is enough nutrients in the soil. It is worth noting that fertilization should not be rushed. Excessive fertilization at once or too high concentration is not conducive to its growth and can even cause root burning and yellow leaves.
IV. Change soil quality
Relatively speaking, it prefers slightly acidic soil. If the soil is alkaline or becomes alkaline, the leaves of the plant may turn yellow. To maintain soil acidity, a little sulfuric acid iron or leftover beer can be mixed into the watering water. The same attention should be paid to the dilution of sulfuric acid iron solution and beer, and the concentration should not be too high.
