Why doesn't Cymbidium blooming?
Do you know about this? The related experience of why Cymbidium doesn't bloom and how to care for it in flower planting will definitely help you. Let's learn about it together!
Speaking of orchids, they are everyone's favorite flowers. Their leaves are graceful and green, and their flowers are elegant and fragrant, which matches the aesthetics of our people. It's June now, which is the blooming season of Cymbidium among orchids. The beautiful flower buds bring bursts of fragrance, making people delighted!
However, some friends' Cymbidium plants look good in growth, but no flower buds appear. This is really frustrating. If you encounter this situation, what is the reason? And how to solve it?
Firstly, the lack of nutrients is related to the Cymbidium not having flower buds.
As we know, the differentiation of flower buds in Cymbidium requires a large amount of nutrients. Without sufficient nutrients, it is difficult for Cymbidium to produce flower buds. Therefore, the planting material should have enough nutrients. When caring for Cymbidium in spring, you should pay attention to using some fertilizers, such as decomposed cake fertilizer, decomposed sheep dung, etc., to enhance the fertility of the planting material and make the plant stronger. Of course, we should also use some slow-release compound fertilizers. The nitrogen in slow-release compound fertilizers can promote the growth of Cymbidium and the germination of leaf buds, while the phosphorus and potassium elements can be stored to meet the needs of flower bud differentiation. By April and May, you should continue to fertilize, preferably using more slow-release compound fertilizers. By June, when the Cymbidium flower buds differentiate, it will be just in time.
If the planting material for our Cymbidium has been used for two or three years, we should pay attention to changing the planting material in time. After all, the nutrients in the planting material are almost exhausted after long-term use, and due to improper watering and fertilization, the planting material may also become alkalized to some extent. These will affect the differentiation of flower buds in Cymbidium. Experienced gardeners will notice that if the planting material is changed in time and the nutrition is sufficient, the flower buds of Cymbidium will germinate earlier and the quality of the flowers will also be higher.
Secondly, the lack of flower buds in Cymbidium is related to lighting and ventilation.
Compared with Moorchid, our Cymbidium prefers soft lighting. Most Cymbidium varieties need to ensure a certain amount of light exposure time for photosynthesis to accumulate nutrients for flowering. Generally, we can expose Cymbidium to soft light for about two hours in the early morning or afternoon, but not expose it to direct sunlight at noon. This soft light is very beneficial for the differentiation of flower buds in Cymbidium. Insufficient light exposure can slow down or even prevent flower bud differentiation. For some specific varieties like Cymbidium giganteum, more light exposure is needed to complete flower bud differentiation, even direct sunlight. Everyone should set the lighting time and intensity according to the characteristics of different varieties.
Cymbidium, like ordinary orchids, prefers a cool and well-ventilated environment. After entering June, temperatures in various places gradually rise, and in some places, the temperature may even exceed 35 degrees. At such high temperatures, it is difficult for Cymbidium to maintain life, let alone produce flower buds. Therefore, we should pay attention to reducing temperature and maintaining a cool environment when the temperature rises to 30 degrees in June. We can spray water on the ground and use fans to create an evaporative cooling effect. This not only provides a cool environment but also increases humidity, allowing Cymbidium to germinate flower buds smoothly.
Thirdly, pay attention to preventing pests and diseases in Cymbidium.
After June, due to the less cool growing environment compared to the mountains, Cymbidium may suffer from some diseases or attract some pests.
Under high temperature and humidity conditions, we should first pay attention to preventing two rot diseases. In addition to maintaining ventilation and coolness, we can spray or pour multi菌灵, methyl thiophanate, etc. Maintaining coolness is the key to prevention. Moreover, Cymbidium may also be infected with scale insects. When infected with scale insects, you can see兰花 dew secretion on the leaves at the beginning, which is actually caused by the nutrients secreted by the scale insects when they absorb the nutrients from the leaves. In severe cases, you can see white spots all over the leaves. When encountering scale insects, you can bury white medicine in the orchid or wipe with alcohol. If it is an orchid garden, you can spray with kerosene emulsion, which is very effective. The pesky scale insects can be eradicated shortly after spraying. It is important to spray evenly, covering both sides of the leaves and the surface of the planting material.
Why doesn't Cymbidium bloom?
Fourthly, summary
If you want Cymbidium to complete flower bud differentiation smoothly, you should also pay attention to slightly controlling water when watering. Slightly controlling water means extending the watering interval and maintaining the slightly dry planting material. This can give Cymbidium a sense of crisis, and it will transfer the nutrients from vegetative growth to reproductive growth, resulting in smooth flower bud development and more fragrant flowers in the future. This may be related to the concentration of cell sap! (If conditions allow, pouring rainwater on Cymbidium may increase the chances of flower bud development)
