A few days after buying the osmanthus tree, all the leaves fell off, how to raise the osmanthus tree

Osmanthus is one of the top ten famous flowers in our country, the fragrance is overflowing when it blooms, it is refreshing, and it is the flower that is most planted in the family potted flowers. But many flower friends in the purchase of osmanthus trees, maintenance after a few days are dropped, what is the cause, how to maintain the osmanthus tree, what to pay attention to in the maintenance?

Causes of defoliation:

Falling leaves due to excessive watering: If there is too much watering or too much water in the pot due to rainy weather, it will be very easy to cause the phenomenon of rotten roots and fallen leaves of the osmanthus tree. Especially for flowers bought online or at the flower market, you must not water too much, you must first adapt the plant to the new environment, and when the root system begins, it means that the plant can absorb water and nutrients normally, and then you can gradually increase the amount of watering.

Dry air is also prone to leaf loss: after transplanting osmanthus trees purchased in autumn, there needs to be an adaptation process, especially the humidity of the environment, if it is too dry, the plant will grow very weakly, and the plant will also be dehydrated. If the osmanthus flower encounters dry weather when the leaves are extracted, the plant will lose its leaves severely.

How should you maintain an osmanthus tree?

The ratio of 2:2 is mixed, but an appropriate amount of cake fertilizer solution can be added as a substrate before planting, which can provide nutrients for the growth of the plant.

Light: Osmanthus likes light, if the light is insufficient during the growth period, the number of flowers of the plant will be reduced, if the light is seriously insufficient, it will lead to the weakening of the photosynthesis of the plant, so that the accumulation of nutrients will be reduced, which will lead to the plant can not bloom, so it is necessary to give sufficient light during maintenance.

Fertilization: maintenance of osmanthus fertilization is very important, potted osmanthus due to the limited potting soil, the maintenance of which is not enough to supply the plant growth needs, so in the maintenance of fertilization should be diligent, so as to make the plant better growth. If the fertilization is insufficient, the plant will bloom less or no flower, affecting the ornamental value.

What should I pay attention to when maintaining osmanthus flowers?

Temperature: In the north to raise osmanthus to pay attention to the temperature, the lowest temperature for wintering in North China is 5 degrees Celsius, if the temperature at night is about 16 degrees Celsius can promote the opening of flower buds, if you can maintain a high temperature of about 20 degrees Celsius, you can prolong the flowering period of osmanthus. It is recommended not to maintain the temperature too high in winter, otherwise it will break the dormancy period of osmanthus and consume a lot of nutrients so that the branches and leaves of the next year will not grow too lush.

Potted osmanthus can not be placed in dusty, air pollution place, which will lead to poor growth of its plants, and the leaves will become smaller and easy to fall off, so it is necessary to prevent osmanthus from being polluted by smoke and dust when breeding.

If too much watering or rainy weather makes too much water in the pot, it will be very easy to cause the osmanthus tree to appear rotten roots and fallen leaves, especially the flowers bought on the Internet or the flower market, must not be watered too much, to make the plant adapt to the new environment, and so on the beginning of the root system to indicate that the plant can absorb water and nutrients normally, then you can gradually increase the amount of watering temperature ventilation is not good to lead to leaf fall, osmanthus trees like a cool and ventilated environment, if the temperature of the environment is too high or poor ventilation, It will make the leaves of the plant wilt and grow poorly, and then the leaves will wither and fall off, for example, the plant grows in a place with serious air pollution, it will grow poorly, and the leaves will become smaller, very easy to fall off, and there will be fewer flowers, or even no flowers.

How to raise osmanthus trees to grow well: remember these three points, there are no more difficult osmanthus trees 2

Osmanthus is a plant that has been cultivated in China for a long time. The open spaces south and southwest of the Yellow River are planted with a large number of osmanthus flowers, which are often potted and ornamental. However, there are often some problems in the maintenance process, such as falling leaves.

So, do you know what happens to the fallen leaves of osmanthus? What should I do in this situation? Under the blooming osmanthus flowers, the gardener uncle will analyze the causes and solutions of the osmanthus tree's leaf loss

1。Osmanthus trees that transplant a large number of fallen leaves often have a large amount of fallen leaves after transplantation. This is mainly due to damage to the root system during transplanting, which hinders the transport of water and nutrients.

At this time, it is in the slow seedling stage. Solution: After transplanting, the osmanthus tree should be watered and placed in a ventilated and cool place to avoid direct sunlight.

The leaves have vitality or new shoots to sprout in order to maintain them normally. A large number of potted osmanthus trees have fallen leaves. 2.

Water causes root rot and leaf loss. If there is standing water, the osmanthus tree will rot its roots, and rotten roots will cause leaf loss. Workaround:

If the ground where the osmanthus trees are planted is waterlogged, ditch the soil is loosened and the excess water is drained. Potted osmanthus stagnant water can be repotted. 3.

Diseases and insect pests lead to osmanthus leaf spot, leaf blight, and anthracnose, which are common leaf diseases of osmanthus. These diseases will cause early leaves of osmanthus flowers, weaken the growth potential of plants, and reduce the flower yield and ornamental value of osmanthus flowers. Workaround:

Strengthen cultivation management to reduce the source of infection. The leaking diseased leaves of potted osmanthus trees should be removed in time, and the diseased leaves of osmanthus trees cultivated in the open field should be completely removed in autumn. In addition, in severe cases, chemical prevention and control should be used scientifically.

Potted osmanthus [Tips] Osmanthus is an evergreen plant that does not lose its leaves even in winter. Even the old leaves will drop for renewal due to metabolism, but mostly in April. Other times, the old leaves are very lifting, and the leaves are less decided.

It should be noted that it is very cold in the north in winter, and osmanthus flowers generally cannot be planted on the ground, but can only be enjoyed in pots.

All green plants can bask in the sun, and they must be exposed to the sun, because only sufficient sunlight can enable plants to photosynthesize effectively and produce nutrients that plants can tolerate to grow. As for why you ask why osmanthus leaves off. Because osmanthus leaves are divided into normal and abnormal.

And there is no specific situation, here can only be divided into normal and abnormal two kinds to give you a brief introduction, the specific analysis by yourself according to the situation. First of all, let's talk about the normal situation, the growth of any plant must have a metabolic process, osmanthus as an evergreen plant, although it is not like deciduous plants will replace the entire leaf at one time in autumn. But the leaves of osmanthus also have a certain lifespan, and when the age of the leaves reaches a certain limit, the leaves of osmanthus will also fall off.

As for the reasons for abnormal defoliation, there are many reasons, such as: improper transplantation methods, in the process of transplanting large trees, due to the small soil balls, osmanthus will shed some leaves on its own in order to survive to ensure survival, improper management of the planting process (such as: waterlogging or lack of water caused by excessive watering and fertilizer damage caused by excessive fertilizer concentration, etc.).

Since the situation is not very clear, I can only give you a rough analysis. If there is anything inappropriate, I hope you understand.

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.

Pictured: A potted osmanthus tree loses a lot of leaves.

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.

Tips] Osmanthus tree is an evergreen plant, even in winter will not fall leaves, even if the old leaves will be lost because of metabolism drop and update, but most of them are in April, other times the old leaves are rarely decided, it should be noted that the northern burning ear potato is cold in winter, osmanthus trees generally can not be planted on the ground, can only be enjoyed in pots.

The reason is that he has osmanthus leaf blight. Osmanthus leaf blight is a plant ring disease that occurs on osmanthus leaves. The disease generally occurs on the leaf edge and tip of osmanthus leaves, which can dry up one-third to one-half of the whole leaf, and then make the whole leaf necrotic and fall off.

Prevention and control methods. 1. Horticultural control.

Strengthen cultivation management. Potted osmanthus should avoid stagnant water, and increase the application of humus fertilizer and potassium fertilizer to improve disease resistance. Diseased plants should be removed in time, and diseased leaves should be removed in winter to feed the infected**.

2. Pharmaceutical prevention and control.

During the onset of the disease, 1:2:100 times lime multiples of Bordeaux liquid can be sprayed in the initial stage, and then 1000-1500 times of 50% benzochiji special wettable powder, or 800-1000 times of 50% carbendazim can be sprayed for prevention and control.

In the season of high temperature and high humidity, it is necessary to spray pesticides regularly to prevent, and use 500 to 800 times of 75% wettable powder to have a good effect, once a week, 2 to 3 times in a row.

Once the disease is found, the diseased leaves should be removed in time, burned in a concentrated manner to reduce the source of infection, and sprayed 200 to 300 times of 25% carbendazim wettable powder, once every 7 to 10 days, until the disease is controlled.

If your potted osmanthus tree experiences a large amount of leaf loss in a short period of time, it may be caused by environmental changes, over- or under-watering, nutrient deficiencies, or other stressors. Here are some suggestions to deal with this:

Check the environmental conditions: Make sure that the osmanthus tree grows in a suitable environment. It needs plenty of sunlight, the right temperature, and the right humidity. Check for sudden temperature changes, excessive cold or dryness, and excessive exposure to direct sunlight.

Adjust the amount of watering: Check the moisture of the potting soil to ensure proper watering. Overwatering or over-drying can cause leaf drop. Water appropriately according to the humidity of the potting soil and avoid stagnant water and excessive moisture of the roots.

Provide the right amount of nutrients: Make sure the osmanthus tree gets the right amount of nutrients. You can use a fertilizer that is suitable for it and apply it according to the product instructions. Nutrient deficiencies can also lead to yellowing and defoliation of leaves.

Avoid excessive drying: In dry weather conditions, there are a few things you can do to increase the humidity of your environment, such as using a humidifier or placing a water tray. Avoid exposing osmanthus trees to strong winds or dry environments with strong winds.

Be patient: Sometimes, deciduous can be a natural life cycle, especially at the turn of the seasons. In this case, the osmanthus tree may be absent at the right time to regrow and get new leaves. Thank you.

Osmanthus is a plant with a long history in China. Osmanthus is usually planted in the south, and osmanthus can only be planted in pots in the north. The common problem encountered when growing osmanthus is the phenomenon of dry leaves, yellow leaves and fallen leaves of the osmanthus tree. The main reasons for osmanthus leaves are as follows?

First of all, insufficient watering and humidity: osmanthus prefers an environment with high air humidity. As long as the surface of the potting soil is dry, do not water less, just water directly.

If the potted osmanthus is kept for a long time in dry weather, the leaves will lose water due to transpiration, and the supplemented root water can easily cause damage to the leaves, dry leaves, yellow leaves, and lose the leaves. Therefore, to maintain the osmanthus in the pot, it is necessary to keep the potting soil breathable and water directly when the surface is dry. Make sure the roots are well hydrated, but not waterlogged.

Second, improper watering and root rot: although osmanthus is afraid of drought, it is also afraid of standing water. If overwatered, potting soil will often accumulate water, and the air in the soil will be squeezed out by the moisture, which can cause the root system.

The roots harden and then damage the capillary roots. It is prone to dry leaf tips, yellow leaves, and leaf droplets. If the situation gets worse, the plant will wither and die.

It is especially important to keep the osmanthus flowers and water them properly.

Third, pests and diseases: Common pests and diseases of osmanthus include brown spots, dead spots, and anthracnose. These pests and diseases can cause osmanthus leaves to fall.

For these pests and diseases, it is necessary to reduce the source of the infestation and quickly remove the remaining flowers and leaves from the pot. For indoor maintenance, carbendazim or mancozeb can be poured once a month to prevent diseased leaves from rotting. In the event of a pest or disease, it can also be done by spraying fungicides**.

Of course, if you use too much fertilizer in normal times, it is easy to cause root damage, and the yellow leaves will fall. Most of the osmanthus flowers purchased by the florist are four-season osmanthus flowers. With proper care, they can bloom in all seasons, and the perfume will fill the entire room.

That's why everyone loves potted osmanthus.
