What if the latest big flower Cymbidium falls off its bud? The reason for the falling bud of Cymbidium

On the eve of the Spring Festival every year, one of the best-selling flowers in local flower markets is Cymbidium. Cymbidium has large flowers and green leaves, which not only has the beauty of ordinary flowers, but also has the unique charm of orchids, implying auspiciousness and wealth, and is very popular with flower friends.

The Spring Festival is coming, whether self-raised or bought in the flower market, Cymbidium is in the bud or flowering stage, we should beware of bud drying and falling off, affecting the Spring Festival flowering. Why do some flower friends have fallen buds of Cymbidium? It's probably caused by four reasons. In order for Cymbidium to bloom smoothly, it is necessary to prevent the bud in advance.

1. The causes and solutions of the bud loss of Cymbidium

1. The ambient temperature is too high to drop the bud.

Cymbidium likes cool growth environment, is not resistant to high temperature and strong light exposure. During budding, the temperature is maintained between 10 and 20 degrees, and the temperature difference between day and night is less than 10 degrees, the bud can develop normally. If the indoor temperature is higher than 20 degrees for a long time, there is no temperature difference, and the bud is not fully developed, it may develop rapidly in advance, the flowering quality is low, and the flowering period is shortened.

When the indoor temperature is higher than 25 degrees for a long time, there is no temperature difference or the temperature difference is relatively small, the vegetative growth rate is accelerated and the leaf buds germinate rapidly, it is easy to appear the phenomenon of bud drying and shedding. In general, in areas where there is no heating at home, it is rare for Cymbidium to drop its bud because of the high temperature. In areas where there is heating at home, the indoor temperature is high and the temperature difference between day and night is small, the phenomenon of Cymbidium falling bud is more likely to occur.

Solution: if the ambient temperature of Cymbidium is higher than 20 degrees for a long time, the temperature difference between day and night is less than 5 degrees, the bud gradually wrinkles and dries off, and there are no other problems in maintenance, it should be considered that it is caused by temperature factors. At this time, Cymbidium can be moved to an environment where the temperature is between 10 and 20 degrees, and the temperature difference between day and night is controlled between 5 and 10 degrees, and the phenomenon of falling buds will gradually improve.

Note: once the flower bud of Cymbidium appears, the bud that has not fallen off should be checked in time. If some buds have been dehydrated and withered, even if they have not fallen off, they should be removed. Because there is no way to recover this damaged bud, it will not only affect the viewing of the whole plant, but also affect our mood. Early removal to save nutrient consumption, but also let us no longer worry about its quality, peace of mind to maintain other healthy buds blooming.

2. sprinkle water on the bud and drop the bud.

Cymbidium likes the moist growth environment, and some flower friends will sprinkle the whole plant from time to time when maintaining the Cymbidium with bud, feeling that this can increase the air humidity and is conducive to the growth and development of the bud. In fact, after Cymbidium has arranged the bell, the bud should be avoided from seeing water, otherwise the bud will wrinkle and fall off easily.

The reason is that Cymbidium is basically raised indoors in winter, and the ventilation condition is poor. After sprinkling water on the bud, the water droplets gather on it for a long time and can not evaporate, which will affect the development of the bud, cause tissue necrosis, and eventually die. Especially when the indoor ventilation condition is not good and the temperature is on the high side, the flower bud is easy to rot or wrinkle and fall off when seeing water, so it can not be opened normally, so we should pay attention to it during maintenance.

Solution: if you have the habit of watering the leaves of Cymbidium, if you find that the bud is rotten or wrinkled and falling off, you should stop watering in time and remove the rotten or wrinkled bud. With more ventilation, the bud can grow normally without damage. I really want to spray water on the leaves of Cymbidium with bud. It is recommended that it be carried out at noon when the weather is fine. After spraying, open the window immediately and let the water droplets evaporate within 5 minutes.

Note: although Cymbidium is also a kind of orchid, it is not quite the same as the Cymbidium and Cymbidium we usually breed. Spraying water on the leaf surface will not only cause the bud to fall off, but also may cause long spots on the leaf surface. Therefore, even if it is not in the flowering stage, direct watering on the leaf surface should be avoided when curing Cymbidium. If you feel that the air humidity is low, affect the growth of Cymbidium, spray around and on the ground, or use a humidifier to humidify. The resistance of Cymbidium cultivated outdoors is stronger than that cultivated indoors, but when it comes to continuous rainy days, it is also best to maintain in places where there is no rain.

3. Too much watering will drop the bud

During the budding period, the watering of Cymbidium should still be dry and wet, and when the pot soil is dry, it should be watered thoroughly at one time. If the plants are watered too often, the roots are retted or rot, the first plant to abandon is the bud, causing the bud to wrinkle and fall off, and some even black rot. In particular, the newly bought Cymbidium had to be watered the previous week, which is more conducive to the plant's adaptation to the home environment.

If you buy it home and water it immediately, it will be more likely to go wrong. Some flower friends think that Cymbidium needs more water when it grows the bud, but it is not the case. The bud does not consume much water, and the pot soil is slightly dry and even conducive to the development of the bud.

Solution: if the Cymbidium is watered more recently, the bud wrinkles and falls off or black rot, you should stop watering immediately, increase the ventilation time, and remove the damaged bud and pay attention to observation. If the bud is no longer wrinkled or black rotten after stopping watering, it can continue to grow. If you stop watering, not only the bud is still falling off, but also the leaf tip is black, the leaf is yellow and other problems, it is best to turn the basin, there is a great possibility of rotting roots.

Note: watering Cymbidium should be carefully watered when the indoor temperature is below 10 degrees. The activity of plants with low temperature is weak, the demand for water is very little, and the risk of watering will be greatly increased. However, Cymbidium cymbidium can not be in a state of water shortage for a long time, and the lack of water will also lead to the loss of bud. How often you water Cymbidium should be decided according to your local temperature and planting materials, instead of following others every few days.

4. unreasonable fertilization to drop the bud.

The flowering period of Magnolia grandiflora is long, and there are more flowers on a single flower arrow. During the growth and development of the bud, the nutrient consumption will be relatively large. Therefore, when raising Cymbidium, it is necessary to fertilize frequently in autumn to prepare for budding and flowering in winter. But if your Cymbidium has begun to arrange the bell, it is best not to fertilize it and wait for the flowers to bloom.

Fertilizing when the bud is large, it is easy to cause fertilizer injury, bud dry and fall off. In particular, it is more likely to be injured by applying quick-acting fertilizer to Cymbidium with bud, such as Huaduo No. 2, potassium dihydrogen phosphate and so on. In a low temperature environment, it is not possible to apply fertilizer to Cymbidium. The basic temperature requirement of fertilization is higher than 12 degrees, so we should pay attention to the temperature change of the environment.

Solution: if the Cymbidium is fertilized recently, the bud falls off, the leaf tip blackens or the leaf looks less glossy, it should be considered to be caused by fat injury. If the application is solid fertilizer, you can get rid of the residual fertilizer, appropriately increase the amount of water, more ventilation, waiting for recovery. If the liquid fertilizer is irrigated, you can pour a lot of water on Cymbidium when the weather is fine, dilute the fertilizer content in the basin, and then ventilate more, so that the water in the basin can evaporate as soon as possible, which can also reduce the harm caused by fertilizer injury.

Note: it is best not to fertilize the newly purchased Cymbidium, because in order to ensure the arrow rate and overall state, they have applied enough fertilizer before leaving the shed to maintain the flowering. Some Cymbidium are sold in the original pot, and a large amount of granular fertilizer can be seen in the basin. If the Cymbidium does not adapt to the home environment, it is easy to cause fat injury, causing falling bud Jiao Tip and so on.

Second, how to prevent Cymbidium from falling into bud?

1. Maintain a reasonable growth temperature

For the maintenance of Cymbidium with bud, it is recommended that the temperature should be kept between 10 and 20 degrees, the maximum should not be higher than 25 degrees, the lowest should not be less than 5 degrees, and the temperature difference between day and night should be kept between 5 and 10 degrees. When the first flower of Cymbidium is in full bloom, the florescence can reach about 3 months when maintained in the environment of 5-15 degrees. In an environment of 15-25 degrees, the flowering period can only last about one and a half to two months.

2. Do a good job of watering

During the period of bud growth, Cymbidium should be watered dry and wet. In general, Cymbidium is raised in a deep basin, and the dryness and humidity of the basin bottom should be fully considered when watering, rather than just looking at the basin noodles. If the ambient temperature is high, the watering should be diligent. If the ambient temperature is read, the watering frequency will be reduced.

3. No fertilizing or watering at the flower bract stage.

After the bud of the orchid has expanded, it should stop fertilizing and wait for the flower to bloom. Especially when the color of the bud is about to bloom, fertilization can easily cause the bud flowers to fall off and greatly shorten the flowering period. When curing Cymbidium with larger flower bud, it should also avoid being drenched in the rain to prevent the bud from falling off.

4. Prevent prolonged exposure to the sun

The growth rate of orchid bud has a lot to do with light. If the bud is small and you want it to bloom quickly, you should shine longer. If the bud is larger and you don't want it to bloom immediately, it should be kept in a place with less light. When the temperature is higher than 25 degrees, the maintenance of Cymbidium with bud should be shaded by 30% to 50% at noon to prevent sunburn of bud and leaf surface and affect ornamental.

5. Multiple ventilation

During the budding period of Cymbidium, more ventilation is beneficial to the growth and development of the bud, it is not easy to drop the bud, and the flower color will be more bright. If the Cymbidium is kept in a place with poor ventilation for a long time, in addition to falling out of the bud, there may also be some problems, such as weak growth, dim leaf color, no luster and so on.

Third, how to make Cymbidium blossom quickly

Some flower friends' Cymbidium is still relatively small and may not bloom during the Spring Festival. So how to make Cymbidium blossom quickly and catch up with the Spring Festival? You only need to do two things:

1. Keep in a warm environment

The relatively small flower bud of Cymbidium is maintained in the environment between 12 and 24 degrees, the plant metabolism is accelerated, and the bud can expand rapidly and bloom in time for the Spring Festival.

2. Increase the lighting time

The big flower flower orchid bud is still relatively small, so when you want to bloom quickly, ensure 4-5 hours of direct light every day, the bud will be able to grow rapidly. But when lighting, we should pay attention to the high noon temperature, strong light, should be appropriate shading, to prevent sunburn buds and leaves. When the light is weak in the afternoon, more exposure to the sun can promote the development of the bud.

The falling bud of Cymbidium is mostly caused by high temperature, frequent watering, fertilization at the bract stage, sprinkling water on the leaf surface of the bud for a long time, or being caught in the rain. As long as these four "pits" are avoided, the bud will grow and bloom smoothly. In the maintenance of Cymbidium with bud, we should do a good job in preventing the bud from falling off. on the one hand, we should ensure that the ambient temperature is not higher than 25 degrees and not less than 5 degrees.

On the other hand, it is necessary to reasonably water, control fertilization, more ventilation, and avoid strong light exposure. The florescence of Cymbidium can be controlled artificially. If you want to blossom early, you can increase the temperature and light time. On the contrary, if you want Cymbidium to bloom later, reduce the light and reduce the ambient temperature, you can delay the flowering time.
