What should I do if the leaves in the lower part of the moon have yellow spots?

Not enough light! Insufficient light, resulting in reduced transpiration of leaves, so the potting soil moisture will remain for a long time, and the root system can not absorb so much water at once, so it will be stuffy roots, if the subject has a tray at the bottom of the pot, then after watering, the water in the tray is not poured out in time, and the drainage hole of the pot will be soaked in water for a long time, so that the permeability of the substrate will be very poor and poor, so it is very easy to stuffy the roots.

Janssen in the picture below is one of the few varieties that change color and have a good flower shape.

Many flower friends buy back a pot of moon season, the leaves are bright and green, the flowers are fragrant, the flowers are brilliant and dazzling, quickly use a precious porcelain pot to give him a new home, live in a mansion, put it indoors or bedroom to watch, watering the words flow everywhere, too unclean, so add a tray, so that a series down, there will be insufficient light, water stuffy roots. You must know that the moon season is a sun-loving plant, you think the indoor is quite bright, in fact, for the moon season light is seriously insufficient, the moon season needs direct light at least 4 hours or more to grow and bloom normally, the moon season in a place with good natural wind will not be easy to get sick, and the indoor light is poor, poor ventilation, the moon season is difficult to raise.

The main reasons for the appearance of macular in the moon season are as follows.

1.Watering too often: This yellow leaf is mostly at the bottom of the moon season and starts to turn yellow from the edges, which is easier to identify. This is easier to handle, reduce the frequency of watering and move the moon out to dry.

2.Watering too little: Watering too little can also cause the leaves to dry out and turn yellow.

If you water too little, the leaves will turn yellow from the center, and the edges will still be green, and gradually all the leaves will turn yellow. As long as you replenish water, the moon season will recover, and the yellow leaves will not recover.

3.Fertilizer: This is easier to recognize, that is, the edge of the leaves in the moon season is in a state of burnt yellow. If you encounter fertilizer damage, you can ignore it, that is, the leaves are ugly, and after a while, the fertilizer will be diluted.

4.Spider mites: This needs to be taken seriously, spider mites are mites, very contagious, and often break out in the high temperature season. Spider mites are also relatively easy to recognize, with small dots on the back of the leaves. If you encounter it, you can destroy it as long as you sneeze it.

5.Iron deficiency: If there is a lack of iron in the month, the leaves will turn pale yellow, but the veins are still green, and the iron deficiency only needs to be diluted with ferrous sulfate and watered after watering.

It is very likely that the plants lack light. Potted plants should be placed in a well-ventilated and sunny area, but avoid direct sunlight. It is also possible that the plant lacks nutrients, and should be supplemented with nutrients and water in moderation.

In the process of growth, the leaves often turn yellow, which is mostly caused by improper cultivation management. Too much water, too little sunlight, too much or too little fertilizer will cause yellowing of leaves, but the yellowing situation is different, and the causes should be carefully observed and analyzed, and corrected.

Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are shrunk and not long, indicating excessive watering. Depot the flowers, put them in a ventilated and cool shade, and dry the soil ball before putting them back into the pot.

Dry yellow: the yellow of lack of water is different from the yellow of more water, the yellow of lack of water is the withered and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Pay attention to watering when watering enough, water thoroughly.

Trim:

After flowering, cut off the dried buds. When the first buds of the moon flowers appear, pick a well-shaped bud and leave it, and cut off the rest. The aim is to leave only one bud on each branch, and the flowers will bloom in full and showy in the future, with large flowers and strong fragrance.

After the first flowering of each season, it must be fully pruned.

Generally, it is advisable to prune lightly, cut off the open residual flowers and weak, crossed, overlapping branches in time, leave stout and young branches only 3-6 cm from the base, leave the outer buds, and prune them into a natural happy shape, so that the plant shape is beautiful and prolongs the flowering period. In addition, potted plants should be selected in the month season, with dwarf flowers and strong aromas.

Summer pruning is mainly to cut off the sprouting branches and flowers of grafted rootstocks, cut off residual flowers and thin excess flower buds with leaves after flowering, reduce nutrient consumption and create good conditions for the next flowering.

The appearance of this yellow color in the leaves of the moon season is likely to be caused by two reasons, and the solution is very simple.

The yellow spot of the leaves may be due to excessive watering, so it is necessary to strictly control the water for the flowers in the later maintenance, or it may be caused by improper fertilization, and it is necessary to fertilize the flowers correctly, or it may be that the flowers suffer from diseases in the process of growth, and appropriate measures need to be taken to prevent and control the diseases for the flowers.

1. Strict water control

The yellow spot on the leaves may be waterlogging in the process of growth, so it is necessary to provide water for the plant reasonably when maintaining the flowers, provide a suitable growth environment for the flowers, and provide water for the flowers is best when the soil is dry, and keep the soil in a moist state.

2. Reasonable fertilization

The yellow spot on the leaves may also be to let the fertilizer contact the leaves when providing nutrients to the flowers, so it is necessary to fertilize the plants correctly when maintaining the flowers in the later stage, and it is best to bury the fertilizer directly in the soil at the roots of the flowers, and wait for the soil to absorb the fertilizer and deliver it to the roots.

3. Prune regularly

The yellow spot of the leaves may also be caused by improper pruning, so it is necessary to prune the flowers reasonably when maintaining the flowers in the later stage, first of all, you need to cut off the branches and leaves that grow poorly or cannot grow normally on the plants to help the plants save nutrients, and at the same time, you also need to cut off the branches and leaves that grow too densely to keep the air circulation.

4. Disease treatment

Disease in the process of growth of the flower will also lead to the appearance of yellow spots on the leaves, at this time it is necessary to immediately cut off the yellow spot on the plant flowers, and regularly spray pesticides for the flowers to eliminate the bacteria on the plants, and also need to ventilate the flowers to improve the ventilation of the environment, to prevent the flowers from suffering from diseases again.

The leaves begin to turn yellow and appear black spots, probably because of too much watering, which causes problems with the roots, so that the health of the plant is threatened, and the leaves will also turn yellow and spotted. In the maintenance, we must pay attention to the application of water, not too much, the frequency can not be too high, if you find that the water is too much, you can discharge the water in time.

If the maintenance time is too long, the potting soil will be compacted, so that the roots of the plant will grow in it, and it will be difficult to breathe, which will also affect the growth of the plant. You can loosen the soil in time, or insert a few holes in the surface of the potting soil to ensure that the root position is breathable.

It is not very resistant to diseases, and it is often infected with diseases, in addition to causing the leaves to not stretch, there will also be yellowing and black spots. It can be sprayed with pesticides for prevention and control, and daily attention should be paid to ventilation prevention and control.

Accidental exposure to strong light during maintenance can cause sunburn on the leaves, resulting in dark spots. You can first change the maintenance position and contact the astigmatism environment.

It is not too difficult to raise the flowers, but it is not a very easy thing to raise well, there will be no problems in raising them at first, but after a long time, you will notice that the flowers have such and such small problems, such as the yellowing of the leaves is a more common distress. If you don't know how to solve it, then don't miss this article today.

What to do if the leaves are yellow, the edges of the leaves are yellow and dry, the leaves are yellow and black, and the leaves are yellow: today I will explain to you the breeding methods and precautions of the leaves and the causes and treatment methods of the yellowing of the leaves.

1. Overwatering.

The leaves of the moon flower have just begun to turn yellow and have black spots, which will cause problems at the roots due to excessive watering, so that the plant will be discouraged and the leaves will turn yellow and spotted. In the maintenance, we must pay attention to the release of water, not too much, the rate can not be too high, if you find that the water is too much, you can immediately discharge the water.

Second, the potting soil.

If the maintenance room is too long, the potting soil will clump, so that the rhizomes of the plant will grow and develop inside, and it will be difficult to inhale, which will also harm the growth and development of the plant. It can be turned over immediately, or multiple holes can be inserted in the surface of the potting soil to ensure that the roots are breathable.

3. Too much fertilizer.

It likes chemical fertilizers, but the fertilizer can not be too much and too strong, otherwise the plant can not bear it, and there will be a large-scale yellowing, and black spots will appear in more serious conditions. If such a thing happens, the fertilization must be terminated immediately, and if it is too serious, the dilution concentration value can be watered.

Fourth, the susceptibility to diseases.

Its disease resistance is weak, and it is often susceptible to diseases, in addition to causing the defeat of the trembling leaves do not stretch, but also yellowing, black spots. It can be sprayed with drugs for prevention, and natural ventilation should be paid attention to for prevention.

Fifth, the sun is too strong.

During the maintenance, it is not small to observe that the heart of the cave touches the strong light, which will cause the leaves to burn in the sun, and then have dark spots. You can change the maintenance area first and touch the natural environment of astigmatism.

Through our introduction, I believe you have a deeper understanding of what is the cause of yellowing and spotting of the leaves in the moon season.

If the root system is damaged due to water hypertrophy, you check the problem below. A place where the sun should be extended in the moon season. It looks a bit like a manure burnt, and the water will drop the leaves first from the bottom.

There is leaf blight in the moon season.

Leaf blight: most of the leaf tips or leaf margins are invasive, at first they are yellow spots, and then rapidly expand inward into irregularly shaped large spots, and the severely damaged whole leaves are wilted up to 2 3, and the diseased parts fade green and yellow, and the brown is dry and falls off. In addition to strengthening the management of fertilizer and water, the prevention and control of the above diseases should be cut off in winter, the diseased branches and leaves should be removed, the underground fallen leaves should be removed, and the initial invasion should be reduced.
