What if the leaves of sweet-scented osmanthus turn yellow

1. Appropriate temperature

15-28 ℃ is the optimum temperature for sweet-scented osmanthus to grow. The summer temperature is too high. If it is not cooled down or still exposed to the sun, its leaves will easily turn yellow. If the winter temperature is too low, if we do not take proper heat preservation measures, it will also cause its leaves to turn yellow. Therefore, when raising sweet-scented osmanthus, we should pay attention to cooling in summer, put it in a more cool place, keep warm in winter, and move it indoors.

Second, reasonable watering

This kind of flower is not resistant to waterlogging. once it is watered too much, it is easy to cause its rotten roots, which will inevitably lead to yellow leaves. Therefore, when planting this kind of plant, we must choose loose soil with good drainage. In addition, daily watering should not be too frequent, nor should we water too much at one time. Just water the basin soil after it is dry.

Third, correct fertilization

If less fertilizer will lead to the yellow leaves of this plant, so we should reasonably apply fertilizer, liquid fertilizer and compound fertilizer during its growing period, but we should pay attention to the concentration should not be too high. In addition, we should change the basin and soil in time to ensure that the soil is not hardened and that there are enough nutrients in the soil. It is worth noting that there is no hurry when applying fertilizer, too much fertilizer or too much concentration at one time is not conducive to its growth, and even cause it to burn roots and yellow leaves.

Fourth, change the soil quality

Relatively speaking, it prefers acidic soil. If the soil is alkaline or alkalized, the leaves of this plant may turn yellow. To keep the soil acidic, you can add a little ferrous sulfate or leftover beer when watering. Also note that both ferrous sulfate solution and beer should be diluted and the concentration should not be too high.
