How to prevent magnolia flowers from turning black after drying 5

To prevent magnolia flowers from turning black after drying, it is necessary to master the correct air-drying method.

There are three major ways to air dry magnolia flowers.

1) Dry quickly over a warm fire, spread the flowers into a thin layer with the corolla downward, so that it dries first, and then flip to dry the rest. If it is simply dried, the color and aroma are poor.

2) Air-drying is the simplest and most commonly used method of making dried flowers, choose a warm, dry, and well-ventilated room, and the indoor temperature should not be lower than 10 degrees Celsius. Well-ventilated cabinets, heated rooms, or penthouses, attics, etc. are all good. Flowers have decorative value during the drying process, so you may want to consider using your bedroom and dining room as a place to dry them.

3) Drying in the microwave oven is a new method, characterized by a short time, no need for anything else** The time of drying in the microwave oven depends on the type of furnace and the number of flowers, some berries are easy to break in the microwave oven, so first put them in a cool, dry and ventilated place to air dry for at least a week.

I think if it can be dried quickly, the kind of blackening should contain the same thing as potatoes or apples, iron or something, to prevent oxidation, maybe add something, but I don't know wow, you try to clamp him in the book a little tighter, and then put it under a heavy object, such as under the bed, generally heavy enough so that there is no air in it should be on the line, don't clip toilet paper in the page to absorb water, too thick air will mold, I used to make dahlias, just to absorb water and add toilet paper to the end of the result.

This is because there is too much moisture in the soil, the soil is moist, and the roots are black. Many people are always afraid of their flowers and fruits lack water, so they often water desperately, but they don't know that this just plays the opposite role, you know, plant growth needs to rely on the roots to absorb water to maintain the growth of its branches and leaves, but the roots need sufficient air to maintain, more water natural air is less, long-term moisture will make its roots in a "suffocation" state, so how can flowers and plants grow well? Generally, long-term wet plants in potting soil will show the phenomenon of "leaf yellowing, wilting, slow growth, gray and dull leaf surface, and leaf loss", and at the same time, long-term moisture will induce the invasion of many germs, and eventually lead to the death of flowers and fruits.

White orchids have fleshy roots that are less tolerant to waterlogging, so their branches turn black.

The branches and leaves of the white orchid are black, which may be caused by the unventilated environment, and it is necessary to improve the ventilation environment maintenance, and the amount of watering needs to be reduced if the water is too much, and the soil can be replaced every 5 days. 1. Environmental ventilation white orchid has high requirements for the environment, if the white orchid is usually placed in a poorly ventilated environment for maintenance, it is easy to make the white orchid branches and leaves black, and it needs to be moved to a ventilated place immediately for maintenance, so that the leaves of the white orchid can be restored. 2. Reduce the amount of water White orchids are more drought-tolerant, usually if you water too much, the roots of the white orchid will rot, which will cause the branches and leaves of the white orchid to turn black, you need to reduce the amount of watering, and cut off the root rot part of the re-maintenance, usually you can water it every 5 days.

3. Excessive fertilization will also affect the growth of white orchids, resulting in black branches and leaves of white orchids and reducing the ornamental value of white orchids. 4. Shade and sun protection usually need to give the white orchid enough light to make it grow more ornamental, but if it is under strong light in summer, it is easy to dehydrate the leaves and turn black, so the white orchid needs to be moved to a cool place for careful maintenance, so that the leaves gradually recover their vitality. 5. Disease prevention and control of white orchid branches and leaves blackening may also be caused by yellowing, anthracnose and other diseases, it is necessary to immediately cut off all the diseased branches and leaves, and improve the growth environment, strengthen the management of watering and fertilization of white orchids, and spray corresponding agents to prevent and control diseases.

This can be root rot caused by overwatering, it is recommended to control the amount of watering, it may also be a lack of light, or it may be too low temperature.

The blackening of the leaves of magnolia is mainly related to insufficient light, excessive watering, low temperature and pests and diseases. If it is caused by overwatering, it is necessary to reduce the amount of watering appropriately; If it is caused by excessive fertilization, the soil needs to be replaced; If it is caused by too much light, the plants need to be moved to a place of astigmatism.

What's wrong with the black leaves of the white magnolia.

The blackening of the leaves of magnolia may be caused by insufficient light, excessive watering, low temperature, pests and diseases, etc., as long as the corresponding solutions are made according to different reasons, the leaves can be restored to green color as soon as possible.

The reason why the leaves of magnolia turn black.

The leaves of the magnolia turn black, probably due to overwatering, causing its roots to be unable to absorb, causing the leaves to turn black, and the forward and too humid environment will also bring pests and diseases to the magnolia, which will cause the magnolia to show signs of blackening leaves.

Magnolia blackening remedy.

The blackening of magnolia may be caused by the unventilated growth environment, and the plants need to be moved to a ventilated place for breeding; If it is caused by overwatering, it is necessary to reduce the amount of watering appropriately; If it is caused by excessive fertilization, the soil needs to be replaced; If it is caused by too strong light, it is necessary to prepare land to move the plants to astigmatism for breeding.

Magnolia can still live when it turns black, its leaves are blackened may be caused by the unventilated environment, and it is necessary to improve the ventilation environment maintenance, and the amount of watering needs to be reduced if the water is too much, and the water can be watered every 5 days, and the soil needs to be replaced if the fertilizer is too much, and the cake fertilizer is applied every half a month, and the light is too strong and needs to be moved to the astigmatism for maintenance.

Do you want to cut the black leaves of the white magnolia.

When the leaves of magnolia are black, it is necessary to remove the diseased leaves and prune the diseased tips in time, and burn the diseased leaves, fallen leaves and stump branches to avoid the environment and soil being too wet, pay attention to drainage, and maintain a good ventilation and light transmission growth environment.

This plant mainly blooms around March, but the duration of the flowers is very short, generally only around ten to fifteen days. Therefore, after it has bloomed, it is necessary to adjust the various stimulus factors in time to promote its subsequent growth.

1) Pruning: After the plant has bloomed, most of the flowers have fallen. However, some of the remaining flowers will remain on the branches.

These residual flowers greatly affect the ornamentality of the plant and also consume some nutrients. So, we should cut them out first. In addition, those withered and diseased branches also need to be cut off.

If you consider its shape, then you can cut it off even if it is too long. However, after pruning, care needs to be taken to keep the wound dry and not to drench it with rain sock water. Remember to ventilate regularly and replenish fresh air.

Also, when watering, don't splash water on the wound. Also, after pruning, you can also use some fermented organic fertilizer such as bean cake. In this way, the plants will be more vigorous after that.

2) Top dressing: Some people think that as long as the nutrients are guaranteed at the time of flowering, it is fine. After flowering, you don't need to care.

Actually, this is not true. Because, it consumes a lot of nutrients in flowering. Then, in order to ensure the normal growth in the future, then it is necessary to top dressing.

After flowering, it is best to apply some more phosphate and potassium fertilizers.

3) Prevention and control of pests and diseases: Under normal circumstances, after the plant blooms, it is easy to be troubled by diseases and pests. The same is true for this plant. Therefore, after flowering, we should actively prevent pests and diseases, rather than waiting for them to happen and then think about remedial measures.

Anthrax.

Magnolia anthracnose mainly affects magnolia leaves. It is one of the common diseases of magnolia.

Symptoms Magnolia anthracnose usually produces irregular lesions from the tip or edge of the leaf, or nearly round lesions on the surface of the leaf. The lesions are brown and watery at the beginning, with small black particles on the surface and dark brown raised lines on the edges, which are clearly demarcated from the healthy parts. The pathogen of magnolia anthracnose overwinters on the tree or fallen leaves with mycelium, and produces conidia in the spring of the following year, which spreads to the plant by wind and rain, and the spores germinate in the water droplets, invade the leaf tissue, and cause disease.

In summer, the peak period of high temperature and humidity is the peak period. The water and fertilizer management of plants is not in place, high temperature and rain, dense and unventilated, and this disease is very easy to occur when the growth declines. Prevention and control method 1

Remove the diseased leaves and cut off the diseased shoots in time. Burn diseased leaves, fallen leaves and stump branches in a timely manner. Avoid excessive humidity, pay attention to drainage, and keep ventilation and light transmission good.

2.At the beginning of the disease, spray 500 times of 50% anthrax Fumei wettable powder, 500 times of 50% antibacterial special wettable powder or 1000 times of 70% methyl tobuzin wettable powder for prevention and control. Spray 800 times of 75% chlorothalonil wettable granules or 500 times of 70% anthrax fomei solution once every 10 days, and spray 3 to 4 times in a row can effectively control the disease.

When the leaves of magnolia turn black, the first thing to determine is that there is a problem with their own maintenance and management, and blind maintenance that does not meet the reasonable needs of the plant will inevitably weaken the growth and development of the plant and produce adverse effects, and the specific reasons are related to the following points.

1. Insufficient light.

Magnolia is a plant with the same view of flowers and leaves, whether it is a leaf or a flower, light is an important energy**. When the light is sufficient, the leaves can better photosynthesize, and the transformed nutrients can be better used by plants, in addition, due to sufficient light, the flower bud differentiation and flower bud development are better, which determines the flowering quality to a certain extent.

However, if the magnolia is not given enough sunlight, it is difficult to promote the photosynthetic function of the plant, so that the branches and leaves can not synthesize more chlorophyll, over time, the leaf color will become lighter or even darker, and the growth of the whole plant will not be good or even weaker, at this time, it is more difficult to want the magnolia to bloom more and more beautifully.

The root system of magnolia will also have fleshy roots, the water storage capacity of fleshy roots is relatively strong, which also makes magnolia intolerant to waterlogging characteristics, in the maintenance process, if you water in an environment with too high humidity for a long time, it is easy to rot the root system, so that the root system can not absorb water and nutrients to grow branches and leaves, and the soil environment is too humid These factors will make the leaves black, dry and even fall off, if not treated in time, the whole plant will wither.

2. The temperature is too low.

White orchids are mainly grown in the southern courtyards, while in the northern regions they are potted in the house, which largely depends on the temperature. Because the northern region is colder, especially in winter, the temperature can be as low as minus 10 degrees, and the white orchid belongs to the warm flower, can not tolerate low temperatures, when the temperature is lower than 10, its growth rate will be greatly slowed down, once it is lower than 5, it will seriously freeze the plant, so that the branches and leaves are soft, black, rotten, and eventually lead to plant wilting.

Prevention and control: when the leaves of magnolia appear black, can not be promoted, according to the different reasons of "symptomatic", such as the leaves turn black due to insufficient light, need to be moved to a well-lit place for maintenance, so that the branches and leaves gradually increase the synthesis of chlorophyll to photosynthesis, thereby changing the leaf color.

If the leaves are blackened due to low temperature, they should be moved indoors in time and measures should be taken to raise the temperature to keep the temperature above 10 as much as possible, so as to ensure smooth air circulation and restore the plant to life.
