How to propagate Cymbidium orchids? Two propagation methods, division is the most practical
As a variety of orchid developed through artificial hybridization, the Cymbidium orchid has strong benefits; simply put, it is highly ornamental, and keeping it at home is not only pleasing to the eye but also purifies the air and beautifies the home. Such a plant is naturally propagated in large numbers, so how do you propagate Cymbidium orchids? Below are two propagation methods for Cymbidium orchids; follow along with the editor to take a look.
1. How to propagate Cymbidium orchids: division / in vitro
As a beginner, mastering the cultivation methods of Cymbidium orchids is enough, but if you are experienced, you should also understand the propagation methods of Cymbidium orchids; only then is growing them truly enjoyable. As for how to propagate Cymbidium orchids, there are mainly two methods: division propagation and rapid in vitro propagation. Let us continue below to see exactly how to do it.
2. Two propagation methods for Cymbidium orchids
(1) Division propagation method for Cymbidium orchids
1. Division time
If you want to divide a Cymbidium orchid, the timing must be chosen well. According to the growth habits of Cymbidium orchids, we can choose the short dormant period after the plant blooms and before the new shoots have grown large; in addition, when dividing, the roots of the plant to be divided must be slightly whitish, soft, and dry, so that the survival rate is high.
2. Selecting divisions
Take a robust Cymbidium orchid that has grown for 2-3 years, remove it from the pot, then break it apart by hand into several sections, each with 2-3 pseudobulbs. After successful division, you can obtain several pots of Cymbidium orchids, but before that, you should apply sulfur powder or charcoal powder to the wounds of the plant to prevent infection.
3. Starting division
Once the above preparatory work is done, the division propagation method for Cymbidium orchids gets underway: place the Cymbidium orchid seedlings in a dry place for 1-2 days, then pot each section separately; after that, the division propagation is successful. Isn't it simple? Beginners can try it too.
4. Care management
After successful division, it does not mean everything is fine; you also need to provide careful care: after division, the Cymbidium orchid needs to be placed in a semi-shaded spot, and you should not water immediately; when the potting soil becomes too dry, spray a small amount of water on the leaves and the surface of the pot; only after new roots grow from the base of the new shoots can you water normally.
(3) Rapid in vitro propagation method for Cymbidium orchids
Besides division, you can also use the in vitro method to propagate Cymbidium orchids. The specific operation: from early January to early March, take the new shoots of the Cymbidium orchid, sterilize them, and inoculate them onto a solid culture medium to obtain test-tube seedlings; then cut off the root system of the test-tube seedlings, take small basal sections, inoculate them onto a solid culture medium and culture for about one month to induce protocorms; remove the protocorms, and new protocorms continue to form at the original site.
The protocorms are alternately cultured on liquid and solid media, rapidly multiplying to form protocorm clusters. Then cut the protocorms open, transfer them to a solid medium to differentiate into plants, then cut them from the base, transfer them to a solid medium and culture for about one month; once complete plants form, they can be transplanted to a shed or greenhouse. This method has low cost and a small chance of variation, so experienced flower growers can try it.
Overall, whether it is division propagation or in vitro propagation, Cymbidium orchids can survive, but for ordinary flower growers, mastering division is enough. If you have a Cymbidium orchid and happen to want to grow one more pot, then why not try it yourself. That is all the editor has to introduce about Cymbidium orchid propagation methods, and I hope it can help everyone.
How to divide and propagate Cymbidium orchids, division propagation methods for Cymbidium orchids
Cymbidium orchids have an elegant columnar form, brilliant and varied flowers, and overflowing fragrance, so Cymbidium orchids are much loved by people, and no small number of people grow them. So how do you divide and propagate Cymbidium orchids? I believe friends who grow Cymbidium orchids all want to know this question, so below we will introduce the division propagation methods for Cymbidium orchids.
How to divide and propagate Cymbidium orchids, division propagation methods for Cymbidium orchids
Cymbidium orchids can generally be propagated by division; when new shoots begin to sprout in spring, it is the suitable time for division. The new plants after division should have more than 3 pseudobulbs. After cutting, wait for the wounds to dry before potting. Normal plants can be divided once every 3 years. When dividing, the knife should be sterilized to avoid causing viral infection. After division, potted Cymbidium orchids should be placed in a warm and humid environment, until the new shoots extend above the soil surface, then they can be managed by normal methods.
Take a robustly growing plant out of the pot, and use a sharp knife to cut at the connection points of the pseudobulbs, dividing it into several clumps; each clump should carry 2-3 pseudobulbs (one of which must have formed in the previous year). Promptly apply sulfur powder or charcoal powder to the cut surfaces, place the newly divided plants in a dry place to air-dry for 1-2 days, then pot them separately. The best time for division is after the flowers fade and before new shoots grow out.
Those who have the conditions can use methods such as sterile sowing, fertilized embryo culture, and tissue culture for large-scale propagation. Note that the pseudobulbs must all be exposed above the surface of the growing medium. After planting, place them in a half-shaded, half-sunny spot. Because the growing medium is moist at planting time, do not water within 1 week after planting; only spray water mist on the leaf surfaces (generally spraying 4-6 times a day), and after 1 week gradually shift to normal care.
Cultivation methods for Cymbidium orchids, propagation methods for Cymbidium orchids
Cymbidium orchid (Latin scientific name: Cymbidium), also called Cymbidium, Chan orchid, Ximbilan, etc. Today we will talk about the cultivation methods for Cymbidium orchids and the propagation methods for Cymbidium orchids.
Cultivation methods for Cymbidium orchids:
1. Soil: Cymbidium orchids require a loose, breathable, well-drained growing medium. Leaf mold soil can be used for planting, or a mix of moss, charcoal bits, fern roots, charcoal, bark chunks, broken bricks, etc. Ordinary potting soil and potting soil for growing Chinese orchids should not be used. Soil with poor aeration and drainage will cause root rot.
2. Watering: Cymbidium orchids like relatively high air humidity. In spring, summer, and autumn, while giving the roots sufficient water, you should often spray water on the leaves. But in early spring after flowering, during the short dormant period of Cymbidium orchids, you must water less, and only when the new shoots grow larger new roots can you water more.
3. Sunlight: Cymbidium orchids need sufficient scattered light for growth. In summer and autumn, use a shade net to provide about 50% shade; on cloudy days or in winter and spring when the sunlight is soft, open the shade net to receive direct light. But during the flowering period, the orchid plant should be placed in a spot with weaker light so that it blooms brightly.
4. Temperature: It likes a warm winter and a cool summer climate, with an optimum growth temperature of 10°C to 25°C. The nighttime temperature should preferably be around 10°C, especially during the flowering period; maintaining the temperature above 5°C and below 15°C can extend the flowering period by more than 3 months.
5. Fertilizing: During the growth period, apply thin fertilizer frequently; you can topdress with dilute chemical fertilizer or compound fertilizer. If more bone meal or decomposed soybean cake fertilizer is applied, the flowers can be made larger and more numerous. Liquid fertilizer should be diluted at 1:1000 and applied once every 10 days. Before flowering, apply sufficient fertilizer; do not fertilize during the flowering period or in the hottest midsummer season.
6. Pests and diseases: If the cultivation environment is poor, Cymbidium orchids are prone to pest and disease damage. Common diseases include Fusarium disease, black rot, soft rot, anthracnose, gray mold, southern blight, etc., so a fungicide should be sprayed once every half month to prevent diseases. Special attention must also be paid to the cleanliness of the environment, water source, planting materials, and tools.
7. Pruning: The pseudobulbs of Cymbidium orchids generally contain more than 4 leaf buds. In order not to disperse nutrients, the newly born small shoots and their growing points must be thoroughly removed. This operation should begin after the flowering period ends, removing shoots once a month, and stop before the new flowering period, so that nutrients can be concentrated, the mother pseudobulb strengthened, and the flowers made larger and more numerous.
Propagation methods for Cymbidium orchids:
Cymbidium orchids are usually propagated by division, which is not only simple but also has a relatively high success rate. Division of Cymbidium orchids is best carried out during the dormant period after the plant's flowering period, when the flowers do not need too many nutrients and the new shoots have not yet grown large, making it relatively suitable for division. Before dividing Cymbidium orchids, several steps are needed. First, dry them appropriately for a period so that the roots turn white and soft. Then cut and divide orchid seedlings that have 2-3 pseudobulbs; you can apply sulfur powder or charcoal powder to the cut wounds to prevent infection. After cutting, let them dry for 1-2 days before potting, and they can grow into new plants. Generally speaking, robust plants can only be divided once every 2-3 years, and it should not be too frequent. The new plants also should not be watered immediately, but water can be sprayed on the leaf surfaces to prevent the leaves from drying out and falling off.
