How to grow osmanthus trees well
Main content introduction: Learn about how to grow osmanthus trees well and the related aspects of home care for potted osmanthus green plants, let's understand together.
If the leaves of osmanthus turn yellow, it is necessary to take countermeasures according to the cause: if it is caused by unsuitable temperature, provide it with appropriate temperature; if it is excessive watering, reduce watering, do not water when the soil is not dry; if it is due to lack of fertilizer or excessive fertilization, fertilize reasonably; if the soil quality is not suitable, change the soil quality appropriately.
I. Appropriate Temperature
15-28℃ is the optimal temperature for osmanthus growth. In summer, if the temperature is too high and no cooling measures are taken or it is still exposed to the sun, the leaves can easily turn yellow. In winter, if the temperature is too low and no appropriate warming measures are taken, it can also cause the leaves to turn yellow. Therefore, when growing osmanthus, pay attention to cooling in summer, which can be placed in a relatively shady place, and pay attention to insulation in winter, which can be moved indoors.
II. Reasonable Watering
This plant does not tolerate waterlogging. Excessive watering can easily lead to root rot, which will cause yellow leaves. Therefore, when planting this plant, it is necessary to choose well-drained and loose soil. Additionally, daily watering should not be too frequent or excessive. Only water after the potting soil has dried.
III. Correct Fertilization
If there is a lack of fertilizer, it can lead to yellow leaves in this plant. Therefore, during its growing period, it is necessary to apply fertilizer reasonably, both liquid fertilizer and compound fertilizer can be used, but the concentration of the applied fertilizer should not be too high. Also, it is important to change the pot and soil in a timely manner to ensure that the potting soil does not compact and has enough nutrients. It is worth noting that fertilizing should not be rushed; excessive or high-concentration fertilization is not conducive to its growth and can even cause root burn and yellow leaves.
IV. Changing Soil Quality
Relatively speaking, it prefers slightly acidic soil. If the soil is alkaline or alkalized, the leaves of this plant may turn yellow. To maintain soil acidity, a little硫酸亚铁 (sulfuric iron) or leftover beer can be added to the water. Similarly,硫酸亚铁 solution and beer should be diluted, and their concentrations should not be too high.
