What is the reason for the dry leaves of the laurel tree

There are two reasons why the leaves of laurel trees dry up, one is watering problems and the other is fertilization problems.

Laurel trees prefer to grow in warm, moist environments, and if they are overwatered, their roots will rot due to standing water. The rotten roots of the laurel tree are blocked from absorbing nutrients, and the leaves dry up.

Laurel trees should not allow long-term water accumulation in the soil of the pot. Once stagnant water occurs, it needs to be cleaned up in time.

In addition, improper fertilization can also lead to dryness. If too much fertilizer is applied, it is necessary to use plenty of water to rinse the potting soil to achieve the purpose of diluting the fertilizer.

Caused by a deficiency of nutrients such as nitrogen, potassium and magnesium.

Lack of nitrogen, potassium and magnesium will cause yellow leaf disease. Symptoms of nitrogen deficiency: The older and lower leaves are greenish and yellow, and the color is more uniform.

Symptoms of potassium deficiency: unbranched young trees, with greenish but inconsistent color on older and lower leaves, yellow mottled leaf margins, and often scorched leaf tips; Branched trees, the leaves are irregular and yellow, and there is no obvious boundary between yellow and green tissues. Symptoms of Magnesium Deficiency:

Unbranched trees, in the older and lower leaves, the leaves are greenish and uneven in color, usually the mesophyll between the leaf veins turns yellow first, and develops inward from the leaf margin, and the leaf veins are still green or yellow-green; Branched trees usually have greenish leaves at the top of the canopy, but the color is uneven, the veins of the leaves turn yellow and extend to the leaf margins, and the veins remain green.

Regarding the problem of osmanthus leaves, I have shared it all with you, and the solution is very simple.

Our country has a long history of osmanthus tree planting, widely planted in many places, such as flower beds, parks, roadsides and courtyards can always see its figure in the bright light, once it is in blooming season, it is fragrant for ten miles, favored by the public. With the development of science and technology, potted osmanthus trees have also appeared, but whether it is domesticated or roadside raised osmanthus trees will also get sick, among which the dry leaves of osmanthus trees are one of the more common diseases. So, what causes the leaves of the osmanthus tree to dry up?

What to do with it after it dries up? Let's think about countermeasures with Uncle Gardener!

1. Watering: The soil of osmanthus should have good air permeability and be afraid of waterlogging. It is best not to dry and not water, and water thoroughly every time. Afraid of waterlogging and waterlogging, if it is harmed by waterlogging, the root system will be black and rotten, the leaf tip will be scorched and withered, and then the whole leaf will wither and fall off, which will lead to the death of the whole plant.

2. Light: Arrange the degree of light and the duration of seeing light of osmanthus flowers.

3. Humidity: In the environment of rising temperature or dry environment, the method of shading and spraying is used as much as possible to improve the environmental humidity. Generally speaking, it is the tip of the old leaves, and it can be improved as long as the humidity is increased by more than 60%.

4. Temperature: The most suitable temperature for growth is 15 28, and low or high temperature may cause problems.

The picture carries this round: the leaves of the osmanthus tree are dry.

5. Ventilation: It is necessary to increase ventilation in a timely manner. It is suitable for planting in a ventilated and light-transmitting place; Like a clean and ventilated environment, not resistant to smoke and dust hazards.

6. Fertilization: Potassium fertilizer and humus fertilizer should be increased to improve its own disease resistance.

7. Germs: The main germ problems are brown spot, blight, and anthracnose;

Potted osmanthus should be removed from diseased leaves in time. Secondly, strengthen cultivation management. Choose fertile, well-drained soil or substrate for planting osmanthus; increase the application of organic and potash fertilizers; The planting density should be appropriate to allow ventilation and light transmission, reduce foliar humidity and reduce the occurrence of diseases.

Scientific use of pesticides for prevention and control.

1. Insufficient light.

1.Reason: Osmanthus trees love sunlight.

If you put it in a place that is too dark and not well lit, the leaves may dry out because you can't receive enough sunlight. 2.Solution:

Move to a place with better lighting conditions for maintenance. Let it be exposed to 6-8 hours of sunlight a day, and it will be ** soon.

Second, the environment is closed.

1.Reason: It is suitable for growing in places with air front circulation.

If you leave it in an airtight place for a long time, you may get dry leaves because you don't get enough fresh air. 2.Solution:

Move to a window or well-ventilated area outside Sixiang and cut off the diseased leaves. It can be restored after some time.

Third, the environment is too dry.

1.Why: It prefers moist growing environments.

If it is placed in a place with dry air for a long time, it may not be able to adapt to it, resulting in the problem of dry leaves. 2.Solution:

Transfer the plants to a higher humidity environment and cut off the completely wilted leaves. It will be restored soon.

We know if it's dry. It is likely that the water will flow more quickly, and the water from the trunk to the leaves will be affected. When this happens, the tips and edges will dry out, and it is important to hydrate at this time.

If there is no sun and there is a lot of rain, the new branches are likely to be brittle and tender, and there will be more water. If the sun suddenly shines, it is very likely that the tips of its leaves will be dried, and if the situation is more severe, all its leaves may dry out. So at this time, we still put it in a dark place, and wait a day or two for it to recover on its own.

If it lacks nutrients, the leaves may be dry, for example, its roots will not have enough oxygen or potassium, and its growth will be affected. At this time, all we have to do is to use compound fertilizer, in addition to a certain amount of pruning on it. Because it makes it more nutritionally balanced, many cells can be exposed to light.

It can not only save the withered leaves, but also make its tree shape beautiful.

Of course, if you have been to our potting soil is finer, there may be a lack of humus. In this way, respiration will be affected, and the edges of the leaves will dry up easily. So we have to replenish it in a timely manner.

Insect infestations can also cause its leaves to dry out, so we still use insecticides to solve this problem. And it's better to find it early and deal with it early, because if it is difficult to solve it after a long time, it may cause it to die.

If the tree is older, it is also likely that its leaves will dry out. Because the tree is evergreen, it still needs to be metabolized, so the leaves are likely to die the next year because its chlorophyll cells have long since become old. In addition, the old leaves are still in the lower part, so they will be grinded, so drying up is also the norm.
