The latest sweet-scented osmanthus trees lose their leaves. What's going on?

Osmanthus fragrans is a kind of tree with high ornamental value and has a very large planting area in our country. Osmanthus fragrans not only has high ornamental value, but also can be used as medicine. Its seedlings are also very popular in the market, but the leaf loss of sweet-scented osmanthus trees often occurs when planting sweet-scented osmanthus trees, which seriously affects the ornamental quality. So why did the sweet-scented osmanthus tree lose its leaves? Let's take a look at it with the editor.

1. Too much water

Osmanthus fragrans in the growth process, the demand for water is still relatively large. However, the waterlogging tolerance of sweet-scented osmanthus trees is really poor, so when we are watering, if we do not control the amount of watering or watering too many times. If the soil produces stagnant water, it will seriously affect the growth and development of the roots. As a result, the absorption and transport function of the root is blocked, and the sweet-scented osmanthus tree will begin to lose its leaves because of lack of nutrition. Therefore, we must pay attention to control the amount of watering, not too much watering, if too much water, less watering or stop watering, and then timely drainage.

2. Improper fertilization

When planting sweet-scented osmanthus trees, although fertilization is indispensable, we must pay attention to controlling the amount of fertilizer when applying fertilizer. We should apply fertilizer reasonably according to the growth needs of sweet-scented osmanthus trees, not too much fertilizer. If too much fertilizer is applied, resulting in the accumulation of a large amount of fertilizer in the soil, then sweet-scented osmanthus trees may burn roots and cause root rot because they are unable to absorb all of them. As a result, sweet-scented osmanthus trees lose their leaves, so we should mainly apply light fertilizer and control the amount of light fertilizer. If you apply too much fertilizer, you can properly water and wash the fertilizer to ensure the growth of sweet-scented osmanthus trees.

3. Excessive illumination

Light is very important to the growth of sweet-scented osmanthus trees. Reasonable light environment can promote the growth of sweet-scented osmanthus trees, improve the flowering rate and enhance the growth ability of sweet-scented osmanthus trees. But we should also note that when planting sweet-scented osmanthus trees, the light should not be too strong. If the light is too strong and the sweet-scented osmanthus tree is in this environment for a long time, it will cause the leaves to be burned by the sun, lose their growth ability, unable to carry out photosynthesis and so on. As a result, the yellow leaves fall, so we should pay attention to shading. Especially in the environment of strong light and high temperature in summer, shading should be done in time to avoid adverse effects.

4. Diseases and insect pests

Sweet-scented osmanthus trees are not very resistant to diseases and insect pests, so they are easily harmed by diseases and insect pests. And there are many types of diseases and insect pests, some of which will cause harm to the leaves of sweet-scented osmanthus trees. Cause the leaves to fall and die, especially in summer, because the air is more muggy, if the ventilation is not good, poor air circulation, more likely to cause diseases and insect pests. Therefore, we should strengthen the prevention and control of diseases and insect pests, if there are symptoms of diseases and insect pests, we should timely check out the specific diseases and insect pests and cut off the damaged branches if necessary, and then take corresponding measures and prescribe the right medicine to the case.

The above is a brief introduction to how the sweet-scented osmanthus tree lost its leaves. That's all for today's introduction. This article is for reference only. I hope it can help you all.
