How to properly care for osmanthus trees
This article provides related information on how to grow osmanthus trees and techniques for their cultivation, answering netizens' questions. Please see the detailed introduction below.
If the leaves of the osmanthus tree turn yellow, it is necessary to take countermeasures based on the cause: if it is due to unsuitable temperatures, provide it with appropriate temperatures; if it is due to excessive watering, reduce the watering, only water when the soil is dry; if it is due to insufficient or excessive fertilization, fertilize reasonably; if it is due to unsuitable soil, appropriately change the soil quality.
I. Appropriate Temperature
15-28℃ is the optimal temperature for the growth of osmanthus trees. In summer, if the temperature is too high and no cooling measures are taken, or if 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, it can also cause the leaves to turn yellow. Therefore, when caring for osmanthus trees, it is important to cool them in the summer by placing them in a cooler area, and to keep them warm in the winter by moving them indoors.
II. Reasonable Watering
This plant does not tolerate waterlogging. If too much water is given, it 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. Also, do not water too frequently or too much at once; water only after the potting soil has dried.
III. Correct Fertilization
If the plant is under-fertilized, it can lead to yellow leaves. Therefore, during its growing period, it is necessary to apply fertilizers reasonably, such as liquid fertilizer and compound fertilizer, but be careful not to apply too high a concentration. Additionally, it is important to change the pot and soil in time to ensure the potting soil does not compact and has enough nutrients. It is worth noting that fertilization should not be rushed; excessive or overly concentrated applications can be harmful to its growth and even cause root burn and yellow leaves.
IV. Change 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 watering. Similarly, it is important to dilute the sulfuric acid iron solution and beer, as the concentration should not be too high.
