What are the key points to note when growing Cymbidium orchids?

Cymbidium orchids are the most fertilizer-hungry of all orchids, so you must never be careless when it comes to applying fertilizer. The flower bud differentiation period of Cymbidium orchids is from August to September, and at this time there must be an obvious temperature difference to promote flower bud differentiation, that is, around 25°C during the day and around 12-15°C at night. During this period, pay attention to temperature, and also pay attention to fertilizing.

The sprouting of Cymbidium orchids has relatively high temperature requirements; if the nighttime temperature exceeds 15°C when the flower buds sprout, the flower buds will wither. There is one more point that also needs attention: good ventilation is a favorable condition affecting the growth and development of Cymbidium orchids. If ventilation cannot be provided in time, especially in summer, it is unfavorable to the normal growth and development of Cymbidium orchids, affects flower bud differentiation, and leads to the phenomenon of only growing leaves and not blooming, which is quite sad.

It is still necessary to learn the key points to note when growing Cymbidium orchids, especially if you grow Cymbidium orchids at home. If your plant is not blooming, it may be that there is a problem with your growing method. Previously, a friend asked the editor whether it was Cymbidium orchids not blooming, and now perhaps the reason has been found. That is all for today's content. Thank you all for reading!

Growing methods and key points to note for Cymbidium orchids

Cymbidium orchids originated in India as tropical plants, and were later introduced to southern China, where they were crossed with local Cymbidium species to breed new varieties. This plant has bright colors and large flowers, with especially good ornamental value, and can be cultivated in scenic areas or made into potted plants for indoor growing. However, many people do not understand its growing methods and do not know what to pay attention to when growing this plant, so today the editor will introduce it in detail for everyone.

1. Soil

When growing Cymbidium orchids, the choice of soil is very important. It likes loose, breathable soil with good drainage. Ordinarily, leaf mold can be used to grow Cymbidium orchids, or moss, charcoal crumbs, bark chunks and other materials can be used to prepare potting soil. Ordinary potting soil cannot be used, because its aeration and drainage are relatively poor, and after planting it will cause the roots of Cymbidium orchids to rot.

2. Water

Only with reasonable watering can Cymbidium orchids grow normally. This plant likes air with high temperature and high humidity. In spring, summer and autumn, the roots should be given sufficient water, and water should also be sprayed on the leaves in time. But after blooming in early spring, Cymbidium orchids enter a short dormant period, and at this time the amount of water supplied must be reduced. Only after the new shoots have grown larger can more water be given.

3. Sunlight

Cymbidium orchids are a sun-loving plant that likes to grow in an environment with sufficient sunlight, but they cannot accept strong light exposure. It is best to place them in an environment with sufficient scattered light. However, after entering the flowering period, Cymbidium orchids should be placed in a place with weaker light, so that the flowers they produce will be more colorful.

When growing Cymbidium orchids, be sure to prevent pests and diseases. When diseases such as leaf spot and gray mold occur, spray carbendazim in time, and after pest insects appear, catch them in time or spray pesticides. In addition, when growing Cymbidium orchids, also pay attention to pruning. Their pseudobulbs generally contain more than four leaf buds. In order not to divide their nutrients, the small newly grown shoots must be completely removed.

Cymbidium orchids are also called Himbi orchids, with upright flower stems, large flowers, a dignified form, and a spectacular presence, and they are highly favored by people. So how are Cymbidium orchids grown? What needs attention during the growing process? Let's take a look at the growing methods and key points to note for Cymbidium orchids.

I. Growing methods for Cymbidium orchids

1. Choice of growing medium and pot: It is advisable to choose a tall cylindrical pot with many holes in the bottom and on all four sides. The growing medium should use bark chunks or fern roots and the like with good air permeability and water permeability. Charcoal, ceramsite and other materials should be added to the lower part of the pot to facilitate drainage.

2. Fertilizing and watering: After division and planting, it should not be watered immediately. If it is found to be dry, water can be sprayed on the leaves and the surface of the pot to prevent the leaves from drying out, falling off, and the pseudobulbs from shrinking. Water only after new shoots and new roots have grown. During cultivation, watering should depend on the weather and the dry and wet conditions. During the vigorous growth period, sufficient water should be supplied to the roots, and in dry and hot seasons, water should be given in time. When the winter temperature is relatively low, the number of waterings can be reduced. The pH of the water used for watering is best at 6.5. Cymbidium orchids relatively like fertilizer. After new shoots grow in spring, a compound fertilizer mainly of nitrogen fertilizer at a concentration of 0.1%-0.2% should be applied once a week. Or use decomposed dilute cake fertilizer water. During the bud stage, quick-acting phosphorus and potassium fertilizers should be applied in advance.

3. Light and ventilation: Direct sunlight is taboo; sufficient scattered light is needed. Under strong summer light, about 50% shading is needed. In autumn, sunlight can be a little more - this is beneficial to flower bud formation and overwintering. In winter, it can be placed in a greenhouse with light. In areas of southern China with strong sunshine and high temperatures, it should be cultivated under a shade shed all year round. To facilitate ventilation, it should be placed on a raised frame and must not be too crowded.

4. Temperature and humidity: During the day, 25°C is suitable; at night, 10°C is good. If the nighttime temperature is higher than 20°C, it will cause the flower buds to wither or affect flowering. In winter, the temperature cannot be lower than 5°C, but also cannot be higher than 15°C, otherwise the flower buds will suddenly elongate. In addition, in summer and when the climate is dry, water should often be sprayed on the leaves, the ground and the frames. At the same time, attention should be paid to preventing and controlling various pests and diseases.

II. Key points to note when growing Cymbidium orchids

1. Fertilizing: The fertilizer composition and content for Cymbidium orchids differ between the growth period and the forcing period, and cannot be treated the same. During the growth period, fertilizer with nitrogen, phosphorus and potassium mixed in equal proportions should be applied, while during the forcing period, the content of phosphorus and potassium should be appropriately increased, generally in a ratio of 1:2:2. The pH of the fertilizer must also be strictly controlled, generally between 5.8-6.2. If the fertilizing target is small seedlings, the fertilizer concentration is best controlled at 3500 to 4000 times dilution, while for medium and large seedlings the concentration should be lowered, about 2000-3500 times dilution. Except in summer, fertilizer is generally applied once every three days. In summer, with high temperatures, keeping it to 1-2 times a month is enough.

2. Organic fertilizer: If the plant is in the tissue culture stage, organic fertilizer must also be applied once a month, and its composition is made by mixing soybean cake and bone meal in a ratio of 2:1 during the growth period.

3. Watering: Watering and fertilizing are generally used alternately. In May and September, watering is generally done once a day. In the high-temperature summer months of July-August, it is twice a day. After the beginning of autumn, when entering the flowering period, keeping watering once every 2-3 days is enough.
