What if 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 flowers sold in the flower market is Cymbidium hybridum. Cymbidium flowers large, green leaves stand upright, not only the beauty of ordinary flowers, but also the unique charm of orchids, meaning auspicious wealth, very popular with flower friends like.

The Spring Festival is coming soon. No matter whether it is raised by oneself or bought in the flower market, the hybrid cymbidium is in the stage of pregnancy bud or flowering. Be careful not to dry up and fall off the bud, which will affect the flowering of the Spring Festival. Why do some of the flowers raised by friends lose their buds? It's probably four things. If you want to let the hybrid orchid bloom smoothly, you must prevent the bud from falling in advance.

1. Causes and solutions of cymbidium flower bud dropping

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

Cymbidium hybridum likes cool growth environment, not resistant to high temperature, not resistant to strong light exposure, during the bud pregnancy period, the temperature is maintained between 10~20 degrees, the temperature difference between day and night is maintained within 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, the flower bud development is incomplete, 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 growth speed of nutrition is accelerated, the leaf bud sprouts rapidly, and it is easy to appear the phenomenon of flower bud drying and falling off. Under normal circumstances, in areas where there is no heating in the home, the phenomenon of cymbidium dropping buds due to high temperature is relatively rare. Home heating areas, indoor temperature is high, temperature difference between day and night is small, the phenomenon of Cymbidium flower bud drop is more likely to occur.

Solution: If the environmental temperature of breeding cymbidium is higher than 20 degrees for a long time, the temperature difference between day and night is less than 5 degrees, the flower bud gradually crinkles and dries off, and there are no other problems in maintenance, it is necessary to consider that it is caused by temperature factors. At this time, the hybrid cymbidium can be moved to an environment with a temperature of 10~20 degrees, and the temperature difference between day and night is controlled between 5~10 degrees, and the phenomenon of flower bud dropping will gradually improve.

Note: Cymbidium once the phenomenon of flower bud off, to check in time has not fallen flower bud. If some flower buds have lost water and shriveled, they should be removed even if they have not fallen off. Because this kind of damaged flower bud, there is no way to recover, not only affect the whole plant to watch, but also affect our mood. Remove early to save nutrient consumption, but also let us no longer worry about its good or bad, peace of mind to maintain other healthy flower buds bloom.

2. Sprinkle the flower bud on the flower bud

Cymbidium flowers like wet growth environment, some flower friends in the maintenance of cymbidium flowers with buds, will occasionally sprinkle the whole plant, think this can increase the air humidity, conducive to the growth and development of buds. In fact, after Cymbidium has been arranged, it should avoid water in the bud, otherwise it is easy to wrinkle and fall off the bud.

The reason is that in winter, cymbidium is basically raised indoors, with poor ventilation conditions. After watering on the flower bud, the water drops gather on it for a long time and do not evaporate, which will affect the development of flower bud, resulting in tissue necrosis and final death. Especially when indoor ventilation conditions are not good and the temperature is high, the flower buds are easy to rot or wrinkle and fall off when they see water, and they cannot be opened normally. Attention should be paid to maintenance.

Solution: If you have the habit of watering the leaves of Cymbidium hybridum, when you find that the buds are rotten or wrinkled, you should stop watering in time, remove the rotten or wrinkled buds, ventilate more, and the buds that are not damaged can grow normally. I really want to sprinkle water on the leaves of Cymbidium with buds. It is recommended to do it at noon in fine weather. After sprinkling, open the window immediately for ventilation, so that the water droplets evaporate within 5 minutes.

Note: Cymbidium is also a kind of orchid, but it is not the same as the spring orchid and cymbidium we usually cultivate. Sprinkling on the leaves will not only cause the buds to fall off, but also may cause long spots on the leaves. Therefore, even if it is not in bloom, when maintaining cymbidium, direct watering of leaves should be avoided. If you feel that the air humidity is low, affecting the growth of Cymbidium, spray around and on the ground, or use a humidifier to humidify. Cymbidium hybridum cultivated outdoors will have stronger resistance than indoor cultivation, but it is best to maintain it in a place where it does not rain when it rains continuously.

3. Too much watering and flower bud dropping

Cymbidium in pregnancy bud period, watering still should see dry see wet, pot soil seven or eight minutes dry when watering, to irrigate one-time watering thoroughly. If watered too frequently, the roots are rotted or rotted, and the first plants to be abandoned are the flower buds, causing the flower buds to wrinkle and fall off, and some even black rot. In particular, the newly bought hybrid cymbidium, the previous week to control watering, more conducive to plant adaptation to the home environment.

If you buy it and water it immediately, the possibility of problems will be greater. Some flower friends think that Cymbidium needs a lot of water when it grows buds, but it is not the case. The buds do not consume much water, and the pot soil is slightly dry and even conducive to the development of buds.

Solution: If the recent watering of Cymbidium is more, the buds are wrinkled or black rot, stop watering immediately, increase the ventilation time, and remove the damaged buds, pay attention to observation. If the flower bud is no longer wrinkled or black rotten after stopping watering, it can continue to grow. If not only the flower bud still falls off after stopping watering, but also the black tip of the leaf, yellow leaves and other problems, it is best to turn over the pot, the possibility of rotten roots is very high.

Note: indoor temperature below 10 degrees, to hybrid cymbidium watering to be cautious. Low temperature plant activity is weak, the need for water is very small, watering more risks will greatly increase. But also can not let hybrid cymbidium in a long time in a state of water shortage, water shortage will also lead to bud loss and fall off. How often to irrigate cymbidium should be decided according to the temperature and planting materials of your own location, instead of following the trend of others to irrigate once a few days.

4, fertilization unreasonable flower bud drop

Cymbidium has a long flowering period, and there are many flowers on a single flower arrow. During the growth and development of flower buds, nutrient consumption will be relatively large. Therefore, when raising cymbidium, fertilizer should be applied frequently in autumn to prepare for winter budding and flowering. But if your cymbidium is already ringing, it's best not to fertilize it and wait for it to bloom.

Fertilization when the bud is larger can easily cause fat injury and the bud will dry up and fall off. In particular, the possibility of fertilizer injury is greater when applying quick-acting fertilizer to cymbidium with flower bud, such as Huaduo No.2 and potassium dihydrogen phosphate. In low temperature environment, it is not allowed to fertilize cymbidium. The basic temperature requirement for fertilization is higher than 12 degrees Celsius, and attention should be paid to the temperature change of the environment.

Solution: if the recent fertilization of cymbidium, appear bud, leaf tips black or leaves look less shiny, it is necessary to consider the fertilizer damage caused. If it is solid fertilizer, you can remove the residual fertilizer, increase the amount of watering appropriately, ventilate more, and wait for recovery. If the irrigation is fertilizer liquid, you can irrigate a large amount of water to cymbidium in fine weather, dilute the fertilizer content in the basin, and then ventilate more, so that the water in the basin evaporates as soon as possible, which can also reduce the harm caused by fertilizer injury.

Note: it is best not to fertilize the newly purchased hybrid cymbidium, because in order to ensure the arrow rate and the overall state of these hybrid cymbidium, enough fertilizer has been applied before leaving the shed, and there is no problem in maintaining it until it blooms. Some hybrid orchids are sold in original pots, and a large amount of granular fertilizer can be seen on the pot surface. If the hybrid cymbidium does not adapt to the home environment under the circumstances of fertilization, it is easy to cause fat injury, causing bud drop and so on.

2. How to prevent cymbidium from dropping flower buds?

1. Maintain reasonable growth temperature

For the maintenance of cymbidium with flower buds, it is recommended that the temperature should be kept between 10 and 20 degrees, the highest should not be higher than 25 degrees, the lowest should not be lower 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, it can be maintained in an environment of 5~15 degrees, and the flowering period can reach about 3 months. In an environment of 15 to 25 degrees Celsius, flowering can only last for about one and a half months to two months.

2. Do a good job of watering

Cymbidium in the long bud period, watering to see dry see wet. Generally, cymbidium is cultivated in deep pots. When watering, the humidity of the bottom of the pot should be fully considered, and only the surface of the pot should not be single. Environmental temperature is high, watering should be diligent, environmental temperature reading, watering frequency should be reduced.

3. No fertilization and no watering during flower bud period

Cymbidium flower bud has expanded, it should stop fertilization, wait for flowers. Especially when the flower bud is about to bloom, fertilization is easy to cause the flower bud to fall off, but also greatly shorten the flowering period. When maintaining large cymbidium flower bud, should also avoid drenching rain, prevent causing flower bud fall.

4. Prevent long-term exposure

Cymbidium flower bud growth speed and light has a great relationship. If the flower bud is small, if you want to make it bloom faster, you should light it for a longer time. If the flower bud is larger and you don't want the horse to bloom, you should keep it in a place with weaker light. When the temperature is higher than 25 degrees, the maintenance of cymbidium with flower buds should be shaded by 30%~50% at noon to prevent sunburn of flower buds and leaves, affecting viewing.

5, more ventilation

Cymbidium in the bud pregnancy period, more ventilation is conducive to the growth and development of flower buds, not easy to drop flower buds, flower color will be more bright. If the hybrid cymbidium is maintained in a place with poor ventilation conditions for a long time, in addition to easy to drop buds, there may also be problems such as weak growth, dim leaf color and no luster.

3. How to make hybrid cymbidium bloom quickly

Some flower friends 'hybrid cymbidium flower buds are still relatively small, during the Spring Festival may not open. So how to make hybrid cymbidium blossom quickly and catch up with the Spring Festival? There are only two things you need to do:

1. Keep it in a warm environment

The flower bud is still relatively small cymbidium maintenance in the environment between 12~24 degrees, plant metabolism accelerated, flower bud can quickly expand, catch up with the Spring Festival bloom.

2. Increase the lighting time

Cymbidium flower bud is still relatively small, want to let fast bloom, every day to ensure 4~5 hours of direct light, flower bud can grow quickly. However, attention should be paid when lighting. When the temperature is high at noon and the light is strong, proper shading should be done to prevent sunburn of flower buds and leaves. At noon afternoon when the light is weak, more sun is able to promote flower bud development.

Cymbidium flower bud drop, mostly caused by high temperature, too frequent watering, fertilization during flower bud period, watering or rain for a long time, as long as avoid these four "pits", flower bud smooth growth and bloom is not a problem. In the maintenance of cymbidium with flower buds, we should do a good job in preventing flower buds from falling off. On the one hand, we should ensure that the ambient temperature is not higher than 25 degrees and not lower than 5 degrees.

On the other hand, we should water reasonably, control fertilization, ventilate more, and avoid strong light exposure. Cymbidium flowering can be artificially controlled, want to make early flowering on the increase in temperature and lighting time. Conversely, delaying the flowering of cymbidium by reducing light and ambient temperature can delay flowering.
