The problem of osmanthus falling leaves in winter, what to do if osmanthus leaves fall in winter

What should we pay attention to when osmanthus always falls off leaves" should be due to three reasons:

Osmanthus loves the sun and should be planted in a sunny place (at least half yang). If the sunlight is insufficient, it will lead to a lack of photosynthesis in the branches and leaves, which will cause the whole plant to grow and synthesize the organic nutrient supply is insufficient, and the leaves are easy to fall off. In addition, the lack of sunlight can also lead to insufficient water evaporation from the leaves, causing circulatory disorders (the circulation of nutrients and water) that suffocate and fall off the leaves.

Osmanthus is afraid of waterlogging, can not be watered every day, watering to control to keep the soil moist, properly so that the root soil can intermittently have a minimum of dryness, but also beneficial to the root system of anti-rot healing. Once the permanent waterlogging will cause the new young roots in charge of absorbing water and nutrients to rot hypoxically (anaerobic rot bacteria also breed in large quantities), part of the rotten roots will cause the inorganic nutrients and water of the plant to be reduced** resulting in defoliation, and the total root rot will lead to the death of the whole plant.

Reasonable fertilization, plants like to apply light and thin fertilizer (only fat dead plants, no thin dead seedlings), as long as the buds are strong and the leaves are green, there is no need to fertilize frequently (too fat flowers are less or even no flowers). Fertilizing too much will cause rotten roots, some rotten roots will lead to leaf loss, and complete rotten roots will cause the whole plant to die.

Whether it is due to one of the above three reasons and cause the leaves, please check with friends, if so, make corresponding adjustments.

Osmanthus is a light-loving tree species, and the planting site should be selected in a sunny place, so that the branches and leaves can be lush and the flowers are dense. Potted plants should be moved into indoor sunlight before winter comes, so as to avoid frost damage and leaf loss caused by osmanthus. Do not water during the flowering season, cover the roots with sandy loam soil in winter and water it.

Osmanthus leaves in winter may be caused by too low temperature, at this time you need to take thermal insulation measures for the plant in time, if it is a potted osmanthus can be moved to indoor maintenance. It can also be caused by overwatering, so it is best to control watering and keep the soil slightly dry.

1. Thermal insulation measures

The leaves of osmanthus are evergreen all year round, and the phenomenon of falling leaves rarely appears, if the osmanthus appears in winter, it is very likely that the temperature is too low, so that the plant produces frost damage, at this time it is necessary to take thermal insulation measures for the plant in time, you can wrap plastic film on the trunk, if it is a potted osmanthus, you can also move it to the indoor insulation.

2. Control watering

The phenomenon of osmanthus falling leaves in winter may also be caused by excessive watering, the growth of osmanthus is inseparable from sufficient water, but the temperature is low in winter, the osmanthus has less demand for water, and the water evaporates more slowly, so it will lose its leaves, at this time it should reduce the amount of watering, and it is most suitable to keep the soil in a slightly dry state.

3. Stop fertilizing

The weather is cold in winter, osmanthus grows very slowly, the demand for nutrients is not high, you can apply fertilizer once before winter, you should stop fertilizing when winter comes, otherwise too many nutrients in the soil will make the plant fertilizer, the phenomenon of falling leaves, this time you need to stop fertilizing immediately.

Under normal circumstances, osmanthus trees do not lose their leaves in winter, and the leaves are emerald green, but if the root system of the plant is damaged, the leaves will turn yellow and fall off. During the maintenance period, an appropriate amount of watering and fertilization is required, if the growth rate of the plant is slow, it is necessary to control water and fertilizer, otherwise the root system will not be able to provide sufficient nutrients and water after damage, which will affect the growth of the plant.

Osmanthus is a common tree or shrub plant of the family Rhinoceros, with a plant height of between 3 and 5 meters, leaves oblong or lanceolate, verdant in color, and serrated edges. The plant is very cold-tolerant, under normal circumstances, in a low temperature environment of about minus 13 degrees, the plant will not be frostbitten, the leaves are still verdant, and there will be no yellowing and falling off.

During the winter, if the root system of the plant is damaged and cannot provide water and nutrients to the plant normally, the leaves of the plant may be yellowing or falling off. In general, it may be related to water and fertilizer, too much water and too high fertilizer concentration can threaten the root system, and when the root system is damaged, the ability to absorb nutrients and water will be reduced.

During the winter, the potted osmanthus planted at home needs to be moved indoors for maintenance before the winter comes, and can be placed on the balcony with sufficient sunlight, which can promote the growth of the plants. According to the growth of the plant, proper watering, if the light is sufficient, you need to increase the amount of watering, properly sprinkle the leaves with water, and replenish water.

Osmanthus likes temperature, during the maintenance period, the temperature suitable for plant growth is between 15 and 28 degrees, to ensure that the plant growth environment is warm enough. During its growth, the plant needs to be watered appropriately and kept in a warm and ventilated environment. If there is too much watering, the environment is closed, and the root system is damaged, and it is easy to induce pests and diseases, which will affect the growth of the plant.

Osmanthus tree will not fall leaves in winter, osmanthus tree is an evergreen tree, in the case of healthy growth, a large number of leaves will not be lost in winter, the branches and leaves are still in a state of verdant and luxuriant, if the osmanthus tree loses a large number of leaves, it may be the cause of soil drought and excessive watering, it is necessary to take the correct watering method to remedy, and the osmanthus tree can not be transplanted in winter, the temperature is low at this time, and the survival rate after transplanting is low.

The osmanthus tree will not lose its leaves in winter, the osmanthus tree is an evergreen tree, in the case of healthy growth, there will be no large number of fallen leaves in winter, the branches and leaves are still in a green state, and the cold resistance of the osmanthus tree is strong, it can tolerate the low temperature of minus 13 degrees, and the osmanthus tree in the southern region and part of the northern region can overwinter in the open air.

Whether the leaves of the osmanthus tree can survive if they fall off, it is necessary to observe the growth state of the root system, after the leaves of the osmanthus tree fall off, the plant should be dug out, and a small hole should be made near the root with a knife, and the internal tissue is fresh, which means that the root system of the plant is active, and the leaves can grow again after careful maintenance, but if the internal tissue is dry and black, it means that the root system is dead, and the osmanthus tree can not survive.

A large number of osmanthus trees may be due to soil drought and excessive watering, the summer weather is hot, the transpiration of the plant is accelerated, the demand for water is larger, at this time do not water, the soil is dry, it will lead to leaf shedding, and the temperature in autumn and winter decreases, when the water evaporates slowly, frequent watering, the root system can not absorb, there will be water accumulation, resulting in rotten roots and leaves.

Osmanthus trees can not be transplanted in winter, although the osmanthus tree has a certain cold resistance, but the premise of cold tolerance is normal growth, the osmanthus tree is dug out for transplanting in winter, the plant has not adapted to the environment, resume growth, the cold tolerance at this time is poor, can not be successfully wintered, so the osmanthus tree can not be transplanted in winter, the correct transplanting time is in the spring and autumn of each year.

The osmanthus tree does not lose its leaves in winter, because the osmanthus tree is an evergreen shrub, the leaves do not fall off in all seasons and are evergreen, if the root system is damaged or infected with diseases, it is easy to fall. When maintaining osmanthus trees in winter, a layer of straw can be wrapped around the trunk to keep warm. When the temperature drops below 5, it is necessary to water the frozen water once to avoid frostbite on the roots.

You can also apply a layer of quicklime to the trunk to keep warm.

The osmanthus tree does not lose its leaves in winter, because the osmanthus tree is an evergreen shrub or small tree of the family Xyloberoceae, which does not lose leaves all year round, and is in an evergreen growth state in all seasons. Leaf loss may occur when the root system is damaged, causing the leaves to fall or if the leaves are falling due to root rot.

1. Wrap the trunk

In order to avoid leaf loss or frostbite of the osmanthus tree in winter, a layer of straw can be wrapped on the trunk and tied tightly with a rope to prevent the straw from being blown away by strong winds. After wrapping, it can play a better role in cold protection and warmth, so that the osmanthus tree can safely overwinter.

2. Watering and sealing frozen water

When the room temperature drops to 5 in winter, you can water the osmanthus tree once frozen water, in order to protect the root system from being frostbitten after winter, pay attention to the watering after watering the frozen water, do not water again, so as not to produce water in the soil, so that the root system of the osmanthus tree is rotten, and when the situation is serious, the whole plant will die.

3. The trunk is painted white

Before winter, you can apply a layer of quicklime water to the branches of the osmanthus tree, the white quicklime can reduce the absorption of heat by the trunk, reduce the temperature difference between day and night, thereby reducing the chance of freezing, and after applying quicklime water, it can also kill the germs and insect eggs produced on the trunk.

The main reason for osmanthus losing leaves is in the roots. Because the roots are unable to absorb water and nutrients, the leaves are all lost. So carefully remove it from the pot first, and then wash the soil from the roots with clean water to check for rot.

Cut off the rotten roots with a sterilized knife to prevent the situation from becoming more serious. After pruning, carbendazim needs to be sterilized to prevent wound infection.

After pruning the roots, the osmanthus should be replanted. Choose a pot of the right size, place a small amount of tiles at the bottom of the pot, and add some river sand to help with drainage. Choose sandy soil to fill the pot, and when planting, you can also sprinkle some rooting powder, and then cover it with soil and compact.

Since the pruning of the roots weakens its ability to absorb water, if the plant has too many branches, it will hinder rooting. Therefore, it is necessary to prune all the dead branches in the upper part, and some overly dense branches should also be pruned to retain nutrients and water for them as much as possible.

After pruning, osmanthus flowers need to be placed in a well-ventilated and cool environment to keep the soil moist. At this time, it is not acceptable to light, let alone fertilization, and it is usually enough to water when the soil is dry. After the plant germinates, it can be placed in a sunny place for normal maintenance.
