What s going on with the osmanthus tree dropping leaves, what s going on with the osmanthus tree dro

Reasons why the osmanthus tree loses its leaves 1, * soil problem The osmanthus tree is a plant that likes slightly acidic * soil, once the * soil environment it grows in does not meet its requirements, its leaves may gradually turn yellow and fall. 2. Root system problems caused by improper watering, fertilization and other root system damage, root damage will directly lead to the obstruction of water and nutrient delivery of osmanthus trees, affecting growth and development, resulting in a large number of leaf litter. 3. Insufficient light osmanthus trees are usually maintained in a ventilated place with sufficient scattered light, and if they are often not exposed to sunlight, they are prone to yellow leaves and fallen leaves.

4. Common pests and diseases of osmanthus include brown spot, blight and anthracnose, which can cause osmanthus defoliation, weaken the growth potential of plants, and reduce the flower yield and ornamental value of osmanthus. What season is the fragrance of osmanthus? What should I do if the osmanthus does not bloom?

The solution to the fallen leaves of the osmanthus tree 1, check the root system to see if there is a root system with black rot, shriveled, yellowing of the root tip, death and other problems, check that there are new roots and so on. If it is a newly transplanted osmanthus, it needs to be maintained for 7-15 days in a ventilated place with sufficient scattered light, and then transferred to normal management after it adapts to the environment. 2. Depotting and pruning: Depotting and cleaning the pots in time, pruning the rotten roots, and then soaking and sterilizing with carbendazim or potassium permanganate, drying the root water and replanting with healthy soil.

3. Scientific water and fertilizer should be watered frequently to avoid insufficient water in the soil, but pay attention to it to avoid stagnant water, and if there is stagnant water, it is necessary to open a ditch to loosen it and drain too much water. In addition, too much fertilization may lead to root burning and affecting the leaves, so it is wiser to wash the fertilizer away with water. 4. Disease prevention and control should reduce the damage and remove the residual flowers and leaves in the pot in time.

Carbendazim can be watered once a month for indoor maintenance to prevent diseased leaves and rotten leaves, and once pests and diseases occur, other fungicides can also be sprayed to diagnose and treat. What season is the fragrance of osmanthus? What should I do if the osmanthus does not bloom?

In general, the phenomenon of osmanthus tree leaves falling occurs from time to time, and the key is to figure out the cause of leaf fall, and then deal with it in time, so as to effectively avoid affecting the healthy growth of osmanthus trees.

The loss of leaves of osmanthus trees is caused by improper management.

1. Excessive water: In the process of growth, the demand for water is still relatively large. However, the waterlogging tolerance of osmanthus trees is indeed relatively poor, so when we water, if we do not control the amount of watering or the number of watering is too much.

If the soil produces stagnant water, it will seriously affect the growth and development of the roots. As a result, the absorption and transportation function of the roots is blocked, and the osmanthus tree will begin to lose its leaves due to insufficient nutrition. Therefore, we must pay attention to the amount of watering, not too much watering, if there is too much water, to water less or stop watering, and then drain in time.

2. Improper fertilization: When planting osmanthus trees, although fertilization is indispensable, we must pay attention to controlling the amount of fertilizer when fertilizing. We should fertilize reasonably according to the growth needs of osmanthus trees, and not too much fertilizer.

If too much fertilizer is applied and a large amount of fertilizer accumulates in the soil, the osmanthus tree will not be able to absorb all of it, so it may cause root burning and root rot. As a result, the osmanthus tree has the phenomenon of losing leaves, so we should mainly apply light fertilizer and control the amount. If the fertilizer is too much, then the fertilizer can be washed with proper watering to ensure the growth of the osmanthus tree.

Fertilization can be selected Bika water-soluble fertilizer.

3. Excessive light: light is very important for the growth of osmanthus trees, and a reasonable light environment can promote the growth of osmanthus trees, improve the flowering rate of osmanthus trees, and enhance growth ability. But we should also pay attention to the fact that when planting osmanthus trees, the light should not be too strong.

If the light is too strong and the osmanthus tree is exposed to this environment for a long time, it will cause the leaves to be burned by the sun, lose the ability to grow, and be unable to photosynthesize. As a result, the yellow leaves of the leaves will fall, so we must pay attention to the shading work. Especially in the environment of strong light and high temperature in summer, it is necessary to shade the sun in time to avoid adverse effects.

Fourth, the harm of pests and diseases: the ability of osmanthus trees to resist pests and diseases is not very strong, and it is easy to be harmed by pests and diseases. Moreover, there are many types of pests and diseases, and some of them will cause damage to the leaves of osmanthus trees.

This can lead to leaf falling and death, especially in summer, because the air is relatively hot, and if the ventilation is not good, the air circulation is poor, and it is more likely to cause pests and diseases. Therefore, we should strengthen the prevention and control of pests and diseases, if there are symptoms of pests and diseases, we must check out what specific pests and diseases are in time and cut off the damaged branches if necessary, and then make corresponding measures and prescribe the right medicine.

Change the soil and change the pot to add nutrients, organic fertilizer mixed with soil to raise, the weight ratio of 1:9, watered through the water.

The loss of leaves and the drying of leaf tips in potted osmanthus are basically caused by root rot due to improper watering and fertilization. If you want to save, you need to depot the roots. When the root system is restored, the new shoots and leaves will naturally grow and become leafy, and they will bloom normally in autumn.

Spring is the best time to save potted osmanthus leaves and leaf tips to dry up, start to deal with it in time, sterilize and disinfect after removing rotten roots, and plant with a medium with good permeability and air permeability, with a high survival rate, early germination of new shoots, about 20 40 days, you can restore vitality, and it will not affect autumn flowering at all.

There are four reasons for the fall of the leaves of the <> osmanthus tree, the first is insufficient watering, the demand for water is relatively large when the weather is relatively hot, the second is too much watering, the plant roots are rotten, unable to absorb nutrients and water from the soil, the third is that the temperature is too low, at this time it should be insulated, and the fourth is insufficient light, can not be in a dark environment for a long time.

1. Insufficient watering.

Osmanthus tree leaves fall may be because of insufficient watering, osmanthus grips the growth of the tree needs sufficient water, in the hot weather, the plant transpiration rate is relatively fast, not watered in time, the plant will secrete a large amount of abscisic acid, resulting in leaf dehydration and falling, at this time to replenish water in time, a small amount of many times.

2. Overwatering.

Osmanthus tree leaves fall may also be overwatered, resulting in plant root rot, unable to absorb nutrients and water from the soil, at this time to discharge the water in time, put it in a light and ventilated place to make the water evaporate quickly, watering to follow the principle of seeing dry and wet, if the situation is more serious, to prune and disinfect the root system.

3. The temperature is too low.

The cold tolerance of the osmanthus tree is relatively poor, and if the temperature is relatively low in winter, the osmanthus tree does not get the first temperature, which will also cause the leaves to fall. At this time, it should be transferred to a warm and translucent place, basking in more sunlight, or you can wrap a layer of plastic film on the outside of the trunk, and then cut off part of the leaves, which can reduce water loss.

4. Insufficient light.

Osmanthus trees like a sunny environment, if they are in a shady environment for a long time, it will lead to poor skin number plants to grow badly, and in serious cases, it will cause mildew and leaf dropping, at this time, the potted plants should be transferred to a sunny environment, especially in winter, to keep ventilation and light, but to avoid blowing off the leaves with too much wind.

<> "What's going on with the osmanthus tree dropping leaves."

1. Too much water.

Osmanthus in the growth, need a reasonable water, it is afraid of waterlogging, if you do not pay attention to the control of water in the daily life, or the frequency of water is too frequent, it may cause damage to the roots, affecting the absorption and transportation function. If the amount of water in the potting soil is not very large, you can loosen the soil inside and put it in a place with good ventilation conditions to promote water evaporation, so that the plants can recover as soon as possible. If you have too much water, consider changing the potting soil.

2. Infection with pests and diseases.

In summer, the air is relatively hot and stuffy, and it is difficult to circulate normally, which may breed diseases and pests, and also cause the leaves to fall under the sun. It is usually necessary to ventilate more, and after being infected with pests and diseases, it is necessary to cut off the diseased branches and spray pesticides**.

3. Nutrient surplus.

Growth needs to be supplemented with nutrients, but if you fertilize regardless of the growth needs, it is likely to lead to a large surplus of nutrients, which will accumulate in the roots and be difficult to absorb, resulting in root burning, and will also cause osmanthus to lose leaves. Usually apply light fertilizer, if you accidentally apply too much fertilizer, you can add water to promote fertilizer discharge.

Fourth, strong sunlight.

Osmanthus trees need sunlight to grow, but if the sunlight is too strong, it will burn the leaves, causing them to turn yellow and fall off. You can quickly move the Guishou Mausoleum flower to a cool place, and wait for it to recover.

Osmanthus tree is a plant with a very long history of cultivation in our country, there are a large number of osmanthus planted in the open field in the south and southwest of the Yellow River, which is often appreciated by potted skinners, but there are often some problems in the maintenance process, such as falling leaves, so, do you know what is going on with the leaves of the osmanthus tree? What should I do if I encounter this?

Below, Uncle Gardener will analyze the causes and solutions of the leaves of the osmanthus tree for you:

1. Transplant a large number of fallen leaves.

Osmanthus trees often lose a lot of leaves after transplanting, which is mainly because the root system is damaged during the transplanting process, and the transport of water and nutrients is hindered, and it is in the slow seedling stage at this time.

Solution: After the osmanthus tree is transplanted, it should be watered thoroughly and placed in a ventilated and cool place for maintenance, not in direct sunlight. When the leaves are alive or have new shoots germinating, they can be maintained normally.

2. Stagnant water leads to rotten roots and fallen leaves.

If the osmanthus tree is waterlogged, it will cause root rot, and root rot will cause leaf loss.

Solution: If the ground osmanthus tree is waterlogged, it is necessary to open a ditch to loosen the soil, drain too much water, and the potted osmanthus water can be repotted.

3. Pests and diseases cause defoliation.

Osmanthus brown spot, osmanthus blight and osmanthus anthracnose are common leaf diseases of osmanthus, which can cause early defoliation of osmanthus, weaken the growth potential of the plant, and reduce the flower yield and ornamental value of osmanthus.

Solution: Strengthen cultivation management and reduce infestation**. Potted osmanthus should be removed from diseased leaves in time, and osmanthus trees cultivated in the open field should be completely removed from diseased leaves in autumn.
