What to Do When Osmanthus Leaves Turn Yellow
Today, I will explain in detail how to deal with the yellowing of osmanthus leaves for netizens. Next, the site editor will introduce the topic to our readers.
What to Do When Osmanthus Leaves Turn Yellow
The best way to prevent osmanthus leaves from turning yellow is to plant them in the most suitable temperature environment for growth. Pay attention to cooling in the summer and keeping warm in the winter. Osmanthus does not tolerate excessive watering, which can easily lead to root rot, and rot will cause yellowing leaves. It is essential to choose well-draining soil and apply fertilizers appropriately during the growing period, making sure not to use too high a concentration.
Why Do Osmanthus Leaves Turn Yellow
There are generally four reasons for the yellowing of osmanthus leaves: one is due to unsuitable temperatures, the second is excessive watering, the third is insufficient or excessive fertilization, and the fourth is due to unsuitable soil quality.
Reasons for Yellowing Osmanthus Leaves
1. Excessive watering: Too much watering causes waterlogging in the potting soil, leading to a lack of oxygen, and the leaves will gradually turn yellow.
2. Drought: Insufficient watering, or not watering for a long time, causes most of the leaf moisture to evaporate, which can also cause the leaves to turn yellow.
3. Over-fertilization: Excessive fertilization, especially too much nitrogen fertilizer, leading to a lack of potassium, naturally causes the leaves to turn yellow.
Dealing with Yellowing Osmanthus Leaves
1. Appropriate temperature: Plant osmanthus in the most suitable temperature environment for growth, pay attention to cooling in the summer, and keep warm in the winter.
2. Reasonable watering: Osmanthus does not tolerate excessive watering, which can easily lead to root rot and yellowing leaves. It is essential to choose well-draining soil.
3. Correct fertilization: Insufficient fertilization can cause yellowing of osmanthus leaves. Apply fertilizers appropriately during the growing period, making sure the concentration is not too high.
Preventing Yellowing of Osmanthus Leaves
Pay attention to reducing the source of damage. In autumn, clear away the diseased and fallen leaves. Also, strengthen cultivation management. It is best to plant osmanthus in fertile, well-draining soil, apply organic and potassium fertilizers, avoid dense planting to ensure good ventilation and light, and reduce leaf surface moisture to prevent the occurrence of diseases.
