Why do the leaves of osmanthus fall off when touched?
For many girls, the leaves fall off easily due to these two reasons and the knowledge of why the leaves of osmanthus fall off, which will be introduced by the editor for netizens next.
Osmanthus is one of the top ten famous traditional flowers in China, so many people know about it and cultivate it. However, it is difficult for新手 gardeners to grow it well, especially in the north, where it is hard to meet the conditions required for its growth.
Especially in summer, the high temperature and lack of ventilation in the north easily lead to leaf drop, which is the most common situation. What are the causes of leaf drop?
The first point is the insufficient humidity, as osmanthus loves high humidity. In the north during summer, the lack of ventilation and high humidity can cause the leaves to curl outward or inward, looking dry and spiritless, and the whole leaf falls off when touched.
When growing osmanthus in summer, it is important to place it in a well-ventilated area and frequently spray the leaves with a fine mist from a spray bottle to maintain the air humidity and prevent leaf curling, ensuring bright and shiny leaves without leaf drop.
This point must be taken care of properly; otherwise, leaf drop will occur, with pale and dull color.
The second situation is caused by improper watering. In the hot and humid summer, if the soil has poor breathability after watering, waterlogging will occur in the potting soil. The high temperature and soil congestion can lead to root rot.
Mild root rot may not cause the whole plant to have rotten branches or leaves, but the leaves will show it clearly by falling off completely because they are thick and will not completely dry out, only falling off when touched at the junction of the leafstalk and stem.
In the hot summer, the potting soil dries quickly, so be sure not to lack water. When the surface of the soil is dry, water it thoroughly to ensure good ventilation. Do not water too frequently, maintaining a moist environment for the soil, allowing it to continue growing during the hot summer season without leaf drop.
These two points are the main causes of osmanthus leaf drop, one due to insufficient humidity and the other due to root rot. Actually, growing osmanthus is not difficult, especially in summer, where a little attention is needed.
Provide shade for osmanthus in summer as it is very sensitive to direct sunlight. If exposed to direct sunlight, its leaves will become dry, severely affecting its growth. Do not let the potting soil lack water, and under good soil conditions, water it thoroughly when the surface is dry to ensure good ventilation.
Provide 1-2 times of foliar spray daily to increase air humidity.
If the growth is slow, apply fertilizer once a month; if the growth is fast, apply it 2-3 times a month, choosing a multi-element fertilizer to supplement.
This way, your osmanthus can safely survive the summer and continue to grow.
In autumn, it will continue to grow and, when it reaches the blooming period, it will produce beautiful flowers with a strong fragrance. In autumn, with suitable temperatures and adequate sunlight, it can grow rapidly.
The above is a detailed introduction of the two reasons for the leaves falling off when touched and why the leaves of osmanthus fall off, for reference by netizens.
