The editor introduces the cultivation techniques for osmanthus and shares tips on how to grow osmanthus plants well. Next, the editor will introduce to netizens.
If the leaves of osmanthus turn yellow, it is necessary to take measures according to the cause: if it is caused by unsuitable temperature, provide it with appropriate temperature; if it is due to excessive watering, reduce watering and only water when the soil is dry; if it is due to lack of fertilizer or excessive fertilization, fertilize reasonably; if it is due to unsuitable soil quality, change the soil quality appropriately.
I. Appropriate Temperature
15-28℃ is the optimal temperature for the growth of osmanthus. If the temperature is too high in summer and no cooling measures are taken or it is still exposed to direct sunlight, the leaves can easily turn yellow. In winter, if the temperature is too low and no proper measures are taken to keep warm, the leaves can also turn yellow. Therefore, when growing osmanthus, it is important to cool down in summer, possibly placing it in a cooler area, and to keep warm in winter by moving it 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 essential to choose well-draining, loose soil. Additionally, watering should not be too frequent or excessive; water only when the potting soil is dry.
III. Correct Fertilization
If there is a lack of fertilizer, the leaves of this plant can turn yellow. Therefore, during its growing period, it is necessary to apply fertilizer reasonably, using liquid fertilizer and compound fertilizer, but be careful not to apply too high a concentration. Also, it is important to change the pot and soil in time to ensure that the potting soil is not compacted and has enough nutrients. It is important to note that fertilizing should not be rushed; excessive fertilization or high concentrations can be harmful to its growth and even cause root burn and yellow leaves.
IV. Changing Soil Quality
Relatively speaking, it prefers slightly acidic soil. If the soil is alkaline or becomes alkalized, the leaves of this plant may turn yellow. To maintain soil acidity, a little sulfuric acid iron or leftover beer can be mixed into the water. However, it is important to dilute the sulfuric acid iron solution and the beer, as the concentration should not be too high.
