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

Cymbidium orchids are the most fertilizer-hungry of all orchids, so when it comes to applying fertilizer, you must not be careless. The flower bud differentiation period of Cymbidium orchids is from August to September, and at this time there must be a clear 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 to fertilizing.

The sprouting of Cymbidium orchids has relatively high temperature requirements. If the night 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 causes the phenomenon of only growing leaves without blooming, which is really sad.

It is still necessary to learn the key points of growing Cymbidium orchids, especially if you grow Cymbidium orchids at home. If your plants are not blooming, it may be that there is a problem with your growing method. Earlier, a friend asked the editor whether it was because the Cymbidium orchid was 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 for Cymbidium orchids

Cymbidium orchids originate from tropical plants of India and were later introduced to southern China, where they were crossed with local Cymbidium plants to breed new varieties. This plant has bright colors and huge flowers, with particularly good ornamental value. It 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. 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. Usually, 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 the leaves should also be sprayed in time. But after blooming in early spring, Cymbidium orchids enter a short dormant period, and at this time the water supply 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 and like to grow in an environment with sufficient sunlight, but they cannot tolerate 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 brilliant.

When growing Cymbidium orchids, be sure to prevent pests and diseases. When diseases such as leaf spot and gray mold occur, carbendazim should be sprayed in time. After pest outbreaks, they should be caught in time or pesticides should be sprayed. In addition, when growing Cymbidium orchids, pruning also needs attention. Their pseudobulbs generally contain more than four leaf buds. In order not to let them consume nutrients, the small shoots that grow must be completely removed.

Cymbidium orchids are also called Himbi orchids. Their flower stems are upright, the flowers are huge, the form is dignified, and the momentum is spectacular, making them highly favored by people. So how are Cymbidium orchids grown? What needs attention during the growing process? Let us look together at the growing methods and key points for Cymbidium orchids.

I. Growing methods for Cymbidium orchids

1. Selection 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 be bark chunks or fern roots with good air permeability and water permeability. Charcoal, ceramsite and similar materials should be added to the lower part of the pot to help drainage.

2. Fertilizing and watering: After division and planting, do not water immediately. If dryness is found, water can be sprayed on the leaves and the surface of the pot to prevent the leaves from drying out and 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-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 frequency of watering 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 with a concentration of 0.1%-0.2% should be applied once a week. Or use fermented dilute cake fertilizer water. During the bud stage, quick-acting phosphorus and potassium fertilizers should be applied in advance in increased amounts.

3. Light and ventilation: Direct sunlight should be avoided, and sufficient scattered light is needed. Under strong summer light, about 50% shading is needed. In autumn, sunlight can be slightly more, which 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 racks and not too densely.

4. Temperature and humidity: 25°C during the day and 10°C at night is good. If the night temperature is higher than 20°C, it will cause flower buds to wither or affect flowering. In winter, the temperature must not be lower than 5°C, but also must not 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 racks. 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 generalized. 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 object of fertilizing is small seedlings, the fertilizer concentration should be controlled at 3500 to 4000 times, and for medium and large seedlings the concentration should be lowered, about 2000-3500 times. Except in summer, fertilize generally once every three days. In summer, with high temperatures, 1-2 times a month is enough.

2. Organic fertilizer: If the plant is in the tissue culture stage, an organic fertilizer should also be applied once a month. Its composition is soybean cake and bone meal prepared 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 and once entering the flowering period, watering once every 2-3 days is enough.
