What to do if the leaves of the osmanthus tree are curled, and what are the causes of the curly leav

When the osmanthus tree is short of water, the leaves of the osmanthus tree will become dull and dull, and begin to slowly lose color and turn yellow, and when there is an extreme shortage of water, the osmanthus tree will lose water in order to protect its body, and the leaves will begin to curl to reduce the evaporation of leaf water.

If the leaves of the osmanthus tree occasionally appear a few curls, check whether it is because of insect pests, the osmanthus tree encounters not many insect pests, that is, red spiders or scale insects, red spiders are relatively easy to kill, can be eliminated with medicine.

If the leaves of the osmanthus tree first grow spots, and then curl, it may be because of the disease caused by bacteria, the common osmanthus tree is brown spot disease and leaf spot, these bacterial diseases cause the leaf veins to lose water, resulting in leaf shedding, you can use 800 times of zinc manganese, the remaining solution after spraying the leaf surface can irrigate the roots, and use it twice in a row with an interval of seven days.

1. The reason for the curling leaves of osmanthus trees is generally white scale insects, which often appear in the rainy season; The needle-like mouthparts of this insect suck the sap in the leaves, causing the leaves to form spots, curls, shrinks and other pathologies.

2. At the onset of the disease, it can be sprayed with 80 dichlorvos emulsion plus 1000-1500 times aqueous solution.

1. Lack of water: If you do not water for a long time during the management period, the leaves will become dull and dull, and will turn yellow. When there is a severe lack of water in the later stage, it begins to curl, which is the state it shows in order to protect the loss of water.

At this time, if you don't replenish water in time, the leaves are easy to fall. It is necessary to water as soon as possible, keep it moist during the growing season, water thoroughly when it is dry, and sprinkle it frequently.

2. Insect pest: If there is occasional curling, it is mostly because of insect pests. Common insect pests are scale insects and red spiders, which should be inspected and treated as soon as possible.

If it is an infected scale worm, it must be sprayed to kill the scale. If it's a spider spider, just dispose of the leaves of the infestation.

3. Infection with diseases: If its leaves are spotted first and then curled, it is mostly because it is infected with bacteria and diseases. Common diseases are leaf spot and brown spot, both of which cause the leaves to lose water and curl.

To spray the drug as soon as possible, you can choose to replace zinc manganese 800 times, and use it to irrigate the roots, so that the effect is better.

Breeding environment. 2. Watering: watering less before the new shoots grow, less watering in the cloudy and rainy season, and more watering in the dry summer.

Watering should be appropriate so as not to let the potting soil appear waterlogged, watering in the summer should be sufficient, you can water once in the morning and evening, shade measures should be used at noon, and water can be sprayed around to achieve the effect of cooling.

3. Fertilization: After germination, apply well-rotted thin cake fertilizer water every 10 days, suitable for applying compound organic fertilizer in July, and phosphorus fertilizer in September can help it grow and flower.

4. Light: Osmanthus likes sunlight, receives about 8 hours of light every day during the flower bud differentiation period, and the temperature is too low in winter and the light is insufficient, which will lead to leaf loss, so it is necessary to take appropriate measures to keep warm.

1. Lack of water osmanthus is suitable for growing in a humid environment, if the soil is too dry, it will lead to curled leaves, at this time you can water the osmanthus tree with nutrient-rich mineral water, soak all the soil, and the leaves of the osmanthus tree can be restored to green in about 1 week.

2. Root rot Osmanthus leaf curl may be due to root rot, the root system can not deliver sufficient nutrients and water to the branches and leaves, resulting in dry and curly leaves, at this time to check the roots of the osmanthus tree, the rotten, blackened root system to prune.

3. Disease invasion Osmanthus is susceptible to disease in the growth process, leaf curl may be the cause of leaf spot, it is necessary to spray zinc-manganese solution on the leaves, spray once every 7 days, and prune off the diseased branches on the osmanthus tree to prevent the spread of pathogens.

4. The light is too strong osmanthus leaf curl may be caused by strong light exposure, the plant likes light, is not resistant to scorching sun exposure, when the light is too strong, the osmanthus tree should be transferred to a ventilated and cool place for maintenance, and cover a layer of sunshade net to avoid osmanthus leaves being burned.

The new leaves of osmanthus are always not growing well, and they are dense, what is the reason?

This may be the osmanthus tree has the insect plague, this pest in the osmanthus leaves to roll up the leaves, suck the water and nutrients of the leaves, the leaves do not get water and nutrients a large number of dry leaves, greatly affect the growth of the osmanthus tree, it is recommended that you use dimethoate and 1605 pesticides together, you can sweep away the pests and kill.

1. Caused by nutrient deficiency. Top application of foliar and compound fertilizers. Mainly phosphorus and potassium fertilizers.

2. Acute anthrax. Spraying fungicide control. Such as mancozeb, etc.

3. Caused by waterlogging. The loose soil can be drained and breathable, and foliar fertilizers such as potassium dihydrogen phosphate can be appropriately sprayed to promote recovery.

Summary. The reasons for the curling of osmanthus leaves are:

1. Lack of water: Osmanthus likes a moist growth environment, and the lack of water in the root system will make the leaves curl.

What causes osmanthus leaves to curl?

The reasons for the curling of osmanthus leaves are: 1. Lack of water: Osmanthus likes a moist growth environment, and the lack of water in the root system will make the leaves curl.

2. Root rot: After the root system is damaged, it cannot transport nutrients and water, so that the leaves are gradually bent.

3. Disease invasion: Osmanthus infected with leaf spot disease leaves will curl.

4. The light is too strong: do not put the osmanthus under the scorching sun, and shade it in summer.

1. It may be a long-term lack of water, and not watering for a long time will make the osmanthus leaves curly.

Solution: Water in time and thoroughly.

2. Long-term overwatering, osmanthus likes moisture, drought resistance, and cannot accumulate water, which will make the roots rot.

Solution: Treat the stagnant water in time and move it to a ventilated place.

3. If you don't see light for a long time, osmanthus trees generally need 6 to 8 hours of sunshine every day, and pay attention to avoid strong light.

Solution: Move the osmanthus tree to a sunny place.

4. Blind fertilization over the chain, excessive fertilization will also make the leaves roll up.

Solution: Just change the soil for the osmanthus tree.

5. Pests and diseases, the main thing that causes the osmanthus leaves to curl and the spikes are mainly white shell insects, which suck the juice in the leaves, which will make the leaves spotted, curly and wrinkled.

Solution: Spray with 80% dichlorvos and 1000 to 1500 times water.

<> "What to do if the old leaves of osmanthus are rolled."

1. Replenish water.

Cause. If the old leaves of osmanthus appear to be curled, it may be due to a long-term lack of moisture. Without water supplementation, growth problems will naturally occur, resulting in poor growth and weakened growth, and in the long run, the upper leaves will not be able to absorb water, causing the old leaves to roll up.

Resolution. Replenish water regularly and water the roots of osmanthus to ensure that the roots can absorb water properly and the leaves will regain their vitality.

2. Contact the sunlight of the Bird Hall.

Cause. In the process of growth, it needs to be replenished by sunlight, and if you don't see light for a long time, there will naturally be a tendency to roll.

Resolution. In the growth and maintenance, it is necessary to see the light of the acacia reasonably, especially in the period of vigorous growth, and the replenishment of light is very important.

3. Drainage and flood prevention.

Cause. Not only does the lack of water cause the old leaves to roll, but if too much water is applied during the growth process, it will also cause the roots to rot, and there will be problems with the transportation function, which will also cause the old leaves to roll.

Resolution. Once too much water is applied, it needs to be discharged in time, and it can not produce waterlogging hazards, and it can be watered thoroughly every time.

4. Natural metabolism.

Cause. If the maintenance method is very normal, it may be a natural situation for the old leaves to curl, which belongs to the metabolism of new friends.

Resolution. In this case, you don't need to interfere with it, just remove the rolled leaves.
