How to raise Cymbidium?

Cymbidium, also known as Cymbidium, cicada orchid, Simbilan and so on, is a general term for the varieties of the genus Cymbidium cultivated through artificial hybridization with bright colors and large flowers. at present, there are nearly 20,000 cultivars, which are very popular in domestic and foreign markets, and have become a large group of orchids. Let's take a look at how to raise Cymbidium.

Propagation methods of Cymbidium

Cymbidium often uses the method of split-plant reproduction, which takes more time than after the plant blossoms and takes place during this short dormancy period before the new bud grows. It should be properly dried before ramet and operated when the roots are slightly whitish and soft. Those with strong growth usually split once in 2-3 years, and each clump of orchid seedlings should have 2-3 pseudobulbs, one of which must be newly formed in the previous year.

How to raise Cymbidium?

1. Soil: Cymbidium requires loose, ventilated and well-drained cultivation substrate, which can be planted with rotten leaf soil or mixed cultivation with moss, charcoal, fern root, charcoal, bark, broken bricks and so on. It is not suitable to use ordinary culture soil and culture soil for planting Chinese orchids. Poorly ventilated and drained soil can lead to root rot.

2. Watering: Cymbidium likes higher air humidity. In spring, summer and autumn, while giving sufficient water to the roots, the leaves should be sprayed frequently. However, during the short dormancy period after flowering in early spring, Cymbidium must be watered less and more watering only when the new buds grow larger and new roots.

3. Sunshine: the growth of Cymbidium needs sufficient scattered light, shading net should be used to shade about 50% in summer and autumn, and open shading net to accept direct light on cloudy days or when the sun is soft in winter and spring. However, during the flowering period, the orchid plant should be placed in a place with weak light so that it can blossom brightly.

4. Temperature: warm in winter and cool in summer, and the suitable temperature for growth is 10 ℃ to 25 ℃. The suitable temperature at night is about 10 ℃, especially when the temperature is above 5 ℃ during flowering, and the flowering period can be prolonged by more than 3 months when the temperature is below 15 ℃.

5. Fertilization: during the growth period, thin fertilizer should be applied frequently, and thin chemical fertilizer or compound fertilizer can be applied. If more bone meal and mature bean cake fertilizer are applied, the flowers will be larger and more. Liquid fertilizer should be diluted at 1 ∶ 1000 and applied once every 10 days. Sufficient fertilizer should be applied before flowering, and no fertilizer should be applied during flowering and midsummer.

6. Insect pests: Cymbidium is vulnerable to diseases and insect pests if the cultivation environment is bad. Common diseases include Fusarium disease, black rot, soft rot, anthracnose, gray mold, white silk disease, etc., so it is necessary to spray fungicide every half a month to prevent the occurrence of diseases, and special attention should be paid to the cleaning of environmental sanitation, water sources, plant materials and utensils.

7. Pruning: the pseudobulm of Cymbidium generally contains more than 4 leaf buds. In order not to disperse nutrition, the new buds and their growing points must be removed thoroughly. This operation should start from the end of the flowering period, pick buds once a month and stop before the new flowering period, so as to concentrate nutrition, strengthen the mother corm and make the flowers bloom bigger and more.

1. Improper watering: although Cymbidium likes to be wet, because of its strong moisturizing ability of potted medium and fleshy root system, it is more resistant to mild drought, so it is suggested that it should not be watered too much and watered with clear water close to room temperature, and no fertilizer should be irrigated during flowering. Fertilizer will be applied after the flowering period, otherwise the flowering period will be shortened and fertilizer damage will occur if the fertilizer is not used properly. Can be controlled according to the room temperature watering interval days, watering should be slowly and slowly, do not pour.

2. Improper transplant: the annual flowers such as Cymbidium on the market are all replaced with more beautiful and noble porcelain pots, but in the process of changing the pots, because the flowerpots are larger, some businessmen add some flower soil to the pots, but some of the flower soil is not rotten, and the damage to flowers caused by organic fermentation after being sold in the pot. The root system is burned and rotten, resulting in yellow leaves or death of the plant. It is suggested that the soil of flower pots should be examined carefully to ensure that the flowers grow healthily.

3. Cold air damage: although Cymbidium is more hardy, it is unbearable at lower temperature. May be hit by cold air on the way home, causing damage to leaves or flowers. It didn't show up at that time, and it wasn't until a few days later that the symptoms slowly appeared. This type of injured flowers can only cut off the yellowing leaves, slowly recuperate, but generally will not die.

4. small environment discomfort: Cymbidium is a kind of flower that likes high air humidity. If the indoor air humidity is low and the temperature is on the high side, it is easy to produce yellow leaf scorched edge phenomenon. You can spray water several times a day to increase the humidity of the small environment. In addition, there may be air conditioning blowing directly or close to the heating and other prone to dry small environment, but also extremely prone to coke edge yellow leaves. When this phenomenon occurs, you only need to adjust it. But the leaves are yellow and can only be cut off.

5, the light is too poor: Cymbidium likes light but is afraid of strong light, generally, scattered light is better, and too weak light will also cause some diseases of its poor growth. generally, indoor appreciation depends on the indoor position to determine the location of flowers. but at this time, we should also pay attention to whether the flowers adapt to the small environment of this position.
