What if the potted Cymbidium does not blossom

For a normal adult Cymbidium, as long as the conjoined plants with more than two or three seedlings are cultivated properly, they can blossom under normal circumstances (a few single seedlings of Cymbidium can also blossom). I often hear some friends say that their potted Cymbidium does not blossom for several years.

First, seedlings (seed seedlings) and tissue culture seedlings do not necessarily blossom even if they have been cultivated for many years, just like other plants, for example, fruit trees cannot blossom and bear fruit until a certain age, and Cymbidium can not blossom until a certain age.

Second, the differences among different varieties of Cymbidium are different, and it is also a common phenomenon that it is difficult for Cymbidium to blossom due to different climatic conditions. For example, in places where the temperature is relatively high and balanced throughout the four seasons, Cymbidium cymbidium can not blossom even if it comes to flower buds because it cannot get normal spring flower conditions (low temperature training). There are also some varieties that do not blossom or can not blossom normally due to the great latitude difference between the north and the south. Now we can make use of air conditioning artificially and regulate the temperature in solar greenhouse to promote the growth and flowering of Cymbidium.

Third, the physiological growth of Cymbidium was disrupted due to various reasons, and new leaf buds burst during the formation of flower buds. In this case, the orchid plant did not have more nutrients to maintain the normal differentiation of flower buds, which led to the cessation of flower bud growth and failure of flowering.

4. Improper cultivation methods may also cause Cymbidium not to blossom. Here, there are mainly the following situations:

The main results are as follows: 1. The plant material of Cymbidium contains too much nitrogen fertilizer and less phosphorus and potassium fertilizer, which leads to excess vegetative growth and inhibition of reproductive growth. Just like the fruit trees that farmers plant in front and behind their houses, because the soil is too fertile and often dumped with garbage and livestock droppings, only branches and leaves do not blossom and bear fruit, and so is Cymbidium. The solution is to replace the plant material with balanced nitrogen, phosphorus and potassium nutrition or increase the application of phosphorus and potassium fertilizer.

2. Excessive watering during flower bud differentiation and wet plant materials will also lead to exuberant vegetative growth and inhibit reproductive growth. Because the plant material is too wet, the nutrients contained in the plant material will often be absorbed and transmitted by the root to participate in the metabolism of the plant along with the water. As soon as the metabolism is strong, the respiration will be exuberant, thus counteracting the products of leaf photosynthesis. The organic matter accumulation of orchid plants is affected, and flower bud differentiation is lack of due power. The solution is to properly control the water of Cymbidium in July and August every year (the flower bud differentiation period of most Cymbidium) to make the plant dry. At the same time, potassium dihydrogen phosphate is sprayed twice or three times every 15 days, which is beneficial to the differentiation and formation of flower buds of Cymbidium.

3. Lack of light is also one of the reasons why Cymbidium does not blossom. Although Cymbidium is a shade-loving plant, it also needs a certain amount of sunlight to maintain normal physiological activities. When the light of Cymbidium is enough, the accumulation of organic matter will be relatively more, and the formation of flower buds will have enough power. Some orchid friends have to raise orchids indoors because of the limitations of conditions, and the flowering is naturally less. The solution is to allow Cymbidium plants that are not exposed to the sun to enjoy the sun as much as possible (of course, no exposure), especially the warm and soft sun in the morning.

In addition to light, the accumulation of photosynthates (organic matter) depends on the temperature difference between day and night. The temperature difference between day and night is small, and the respiration of Cymbidium is exuberant at night, which will consume the photosynthates produced by Cymbidium during the day. Therefore, in the flower bud formation period, the day-night temperature difference is small, Cymbidium is often difficult to blossom in the area should consider the artificial creation of day-night temperature difference.

Fifth, there is also a situation that Cymbidium can not blossom for its own special reasons, or a very small number of Cymbidium do not like to bloom. This is probably the phenomenon of infertility in plants (Cymbidium).

How to make Cymbidium blossom again?

Cymbidium bought during the Spring Festival, if you want to make it blossom again, you should be very familiar with the ecological habits of this flower and the law of growth and development, and prepare the environmental conditions for cultivation according to local conditions.

After shedding the orchids, cut off the residual flowers and plant them in tile pots instead, with large bottom holes and broken tiles as drainage layers to ensure smooth drainage. Large plants with about 10 seedlings can be divided into two pots. Keep 1 beat 3 old plant material on the pot and add new plant material. Be careful to expose all the false bulbs on the surface of the substrate when planting.

Irrigate the substrate after planting, so that the soil debris in the basin is quickly discharged from the hole at the bottom of the basin with water, and then the planting pot is placed overhead where the scattered light is sufficient. Within one week of the first planting, only spray to the leaf surface, after the new root is sent out, it is necessary to keep sufficient water.

Suggestions on the compound flower of Cymbidium:

1. As Lunar New year Flowers, they usually bring pots, so there is no need to change pots. After checking a lot of masters of compound flowers, they do not change pots, and the long roots of orchids in the pots do not need to be sorted out. The master said that Cymbidium blossoms in a small pot.

2. If the bare root seedlings do not have pots, they can be cultivated with common plants such as medium-sized granular bark and humus soil. The pots should not be too large, and the planting method is similar to that of national orchids. If the number of seedlings in a pot is too much, it can be divided into pots. Generally, 3-4 seedlings are divided into one pot, and it is not easy to reflower if there are too many seedlings.

3. Balcony culture needs to be cultured in sunny places in spring, without shade, and in summer, the key is to need good ventilation and more compound fertilizer (several trees are slightly more than the demand of national orchid culture, that is, thin fertilizer is applied frequently, such as the same fertilizer. National orchid needs to be diluted 1000 times, then Cymbidium cymbidium needs to be diluted 1000 times), watering frequently (can not dry thoroughly, dryness is very harmful to orchids It can be watered with 30% water content. You can leave it outside if you can. Generally speaking, it is extensive management.

4. Cymbidium needs vernalization. At the end of autumn, you can move into the house after raising the temperature below 14 degrees at night for about 55 days. Spray ventilation is needed to cool down if it is higher than 30 degrees in summer.

5. The disease of Cymbidium can be treated in the same way as the national orchid.

Summary: mainly strong light, more fertilizer, autumn temperature difference to promote flowers, to meet these conditions can be compound flowers.
