What is the reason for the non development of the leaves in the moon?

The main reason is that the main reason is that it has suffered from the harm of pests and diseases, or it is a disease, when the leaves do not develop, you should first check whether there is white powder on the back of it, if there is powdery mildew, at this time you need to be timely **, or have fertilizer, then there will be macular and white spots.

It could be because of pests and diseases, it could be due to poor cultivation management, too much or too little water, or it could be due to lack of sunlight.

Yueji still prefers a relatively cool environment, and if the leaves do not spread, it should be placed under the sun to absorb too much sunlight, or it may be caused by no watering or lack of nutrients.

It may be caused by pests and diseases.

In summer and autumn, the flowers are particularly prone to leaf deformities, sometimes accompanied by a large number of brown scars, in fact, this is the month of thrips insect infestation.

Thrips are a very small insect, generally in summer we can not see the insects, but the summer thrips are very harmful to the moon, which will lead to deformities in the development of leaves and buds, growth stagnation, and seriously affect the growth of the moon.

When your leaves are smaller, deformed, curled, and have many brown spots, then it can be determined that it is caused by thrips insect infestation, and you should spray it with grassworm in time**.

It is best to choose the time of spraying in the evening, because thrips are active at night. When spraying, it is necessary to spray on the front and back of the foliage, branches and potting soil, so as to have a better insecticidal effect.

Improper maintenance can also lead to leaf deformities, such as fertilizer damage caused by excessive fertilization. Usually thin fertilizer can be applied diligently with pica foliar fertilizer.

It may be a lack of nutrients, it is very likely that you did not top dressing in time, it may also be a lack of light, it may also be a lack of trace elements, or it may be a lack of organic fertilizer.

The reasons for the curly and wrinkled new leaves of the moon season are as follows:1. Powdery mildew, if the old leaves and new leaves of the plant show a tortuous scene of leaves, this indicates that the plant has had this kind of disease, which will not only affect the leaves, but also cause the plant to develop poorly, and need to be sprayed for treatment immediately.

Second, pests and diseases, if the newly grown leaves in addition to twists and turns, there are very small insects below, then there can be a disease and pest, at this time, if not treated in time, the leaves can be eaten by insects.

3. Waterlogging, if we give too much water in the maintenance, and the flower soil drainage system is not good, it will also cause the leaves of the plant to curl.

The reason why the moon season does not grow leaves.

1. Insufficient light: The leaves do not grow in the moon season may be caused by insufficient light, and it is necessary to move the position of the plant to place it with sufficient scattered light.

2. Insufficient nutrients: the leaves of the moon flower do not grow may also be caused by insufficient nutrients, and it is necessary to carry out top dressing in time to help it grow leaves.

3. Soil discomfort: The leaves of the moon flowers do not grow may also be caused by soil discomfort, and the regret needs to be replaced with new soil for re-maintenance.

The moon season does not grow leaves treated.

1. Cut off blind branches and prune in time: cut off some blind branches, overly dense branches, and residual flowers on the branches before the moon season, so as not to consume a lot of nutrients of the plant.

2. Fertilization: The fertilizer is not picky in the month, the seedlings can be sprayed with gibberellin, and the large pot is directly used with organic fertilizer, chicken manure, and sheep manure, and fertilizer is given once in ten days and half a month.

Precautions for lush breeding in the monthly season.

It has strong cold resistance in the moon season, and can directly return to the normal winter in the south, and should be moved to indoor ventilation for maintenance in the north. Note that do not prune after the flowers wither in October, and apply phosphate fertilizer once to enhance cold tolerance.

The lack of leaves in the moon season may be caused by insufficient light, and it is necessary to move the position of the plant to release it to a place with sufficient scattered light; The lack of leaves may also be caused by insufficient nutrients, and it is necessary to carry out topdressing in time to ensure the growth of the plant; The leaves do not grow and may also be caused by soil discomfort, which needs to be replaced with new soil for re-maintenance.

One, insufficient light.

The lack of leaves may be caused by the lack of light, because the growth of the moon season has a very high demand for light, and it is in a dark environment for a long time, which seriously affects the growth of the plant, resulting in the lack of leaves in the moon season. It is necessary to move the plant and place it in an environment with plenty of scattered light.

Second, nutrients are insufficient.

The growth and flowering of the plant will consume a lot of nutrients, if the top dressing can not be carried out in time, the plant can not grow normally, and there will be no leaves. Top dressing must be carried out in time, and thin liquid fertilizer must be selected for proper application to ensure the growth of plants.

Third, the soil is not suitable.

If the soil is not changed for a long time, it will lead to the lack of nutrients in the soil, the occurrence of soil compaction, and will also lead to the lack of leaves. It needs to be resoiled and replaced with new soil for re-maintenance.

The causes of curly and dry leaves are: too much light, waterlogging, and lack of nutrients.

1. The light is too strong

After being exposed to strong light for a long time, the leaves will curl and wilt, so it is necessary to move them to a semi-shady environment first, and spray water mist around the plant to improve the surrounding humidity environment, so as to promote the gradual recovery of vitality in the month and night, and pay attention to the summer season, you need to block 50% of the sunlight for the plants.

2. Waterlogging

When the soil is too wet, the leaves of the plant will curl and wilt, at this time, it is necessary to take the moon out of the soil, drain the excess water in the pot soil, and cut off the rotten roots of the moon season to make the plant in a healthy growth state.

3. Lack of nutrients

At this time, it is necessary to apply a compound fertilizer rich in nutrients to it, and with the operation of turning the soil, the fertilizer will be buried deep in the soil, so as to promote the root system of the moon season to better absorb nutrients.

Growth habits

Although the requirements for climate and soil are not strict, it is more suitable for loose, fertile, rich in organic matter, slightly acidic and well-drained micro-acidic sandy loam. It prefers a warm, sunny, well-ventilated environment with a warm and humid climate. Generally, 22 to 25 is the most suitable temperature for growing in the month.

The optimum temperature for most varieties is 15-26 during the day and 10-15 at night. In winter, the temperature is low and goes into dormancy at 5. Some varieties can withstand low temperatures of 15 and high temperatures of 35; When the temperature lasts above 30 in summer, it enters semi-dormancy, and the plant grows poorly, although it can also give birth to buds, but the flowers have few small petals, the color is dull and dull, and it loses its ornamental value.

1. Improper watering.

Moonflower is an excellent ornamental flower, and if the leaves turn yellow and wilt during the growth period, it may be caused by improper watering. Moonflowers need water during the growth period, but they are not waterlogging tolerant and need to be watered in moderation. If you water too much, the leaves will turn yellow after the root system is damaged, and if you don't have enough water, the leaves will also wilt and turn yellow after lack of water.

2. Insufficient fertilizer.

Moonflowers need fertilizer during the growth period, and they need the right amount of fertilization to promote the growth of flowers and leaves. During the maintenance period, the fertilizer is insufficient, and the branches and leaves of the moon flower lack nutrients, and the branches will be weak, the leaves will turn yellow, dry out and wilt. If the moon flower lacks fertilizer, it needs to be fertilized, and the cavity should be adjusted and the number of fertilization should be adjusted in the later stage.

3. The light is too strong.

Moonflowers like light and are suitable for growing in a sunny environment, but they are not tolerant to strong light. During the summer, if the sun is too strong, if you put it outdoors in a sunny place, the flowers will get sunburned. Under strong light, the leaves of the moon flower will become dehydrated, dry, yellow or wilted, and shade needs to be done during the maintenance period.

4. Pest and disease infestation.

The flower is less resistant to disease and is susceptible to pests and diseases during the growth period. Common pests and diseases of moonflower are anthracnose, black spot, scale insects, aphids and red spiders. After the moon flower is attacked by diseases and insects, the growth of the moon season deteriorates, and there will be disease spots or insect eggs on the leaves, and the leaves will curl and balance the round, dry, yellow and wilt.
