When the outdoor temperature is lower, the orchid needs to enter the house, and is it okay to not ve

No, if the leaves are not ventilated, they cannot breathe fresh air, so they cannot carry out effective photosynthesis, resulting in the accumulation of their own nutrients, so no ventilation is not conducive to the growth of orchids.

Winter orchids need ventilation after entering the house, but the requirements for ventilation are not as high as the growing season, orchids in the growing season, the body metabolism is active, the demand for oxygen and carbon dioxide is large, ventilation is needed to supplement fresh air, on the one hand, it can make orchids grow well, on the other hand, it can reduce the occurrence of diseases, although the physiological activity of orchids in winter is reduced, but it is not completely stopped.

When the outside temperature drops below 18 degrees, orchids need to come in. Proper ventilation is also required after entering the house. This helps the orchid to grow well.

In winter, can indoor-grown orchids be moved out of the sun to bask outside? After reading it, I understand.

If the temperature is always above zero in winter, then the orchid will basically not freeze to death, but if the temperature is always below -10 degrees, then the plant is likely to freeze to death, especially if it is maintained in a pot. At this time, it is necessary to take measures to keep the plants warm, and you can wrap the pot with foam or cotton cloth to prevent the plants from freezing to death in winter.

The root system of the orchid is a fleshy root, and the water-filled orchid root is most afraid of freezing, once the moisture in the orchid root meets the strong cold air and freezes, it will definitely damage the root cells, which is the mechanism of orchid freezing. In fact, most of the orchid leaves are not afraid of freezing, and the most frost-resistant one may be the orchid, which is rarely frozen when it is minus 10 degrees in the wild.

Many orchid friends ask whether orchids can be maintained outdoors in winter, but they should pay attention to the following points: first, watering is best changed at noon, second, do not let the rain and snow fall in the open air, third, if the temperature reaches below minus eight degrees, it is recommended to move to the home for maintenance.

Orchids are very sensitive to the cold, and when the outdoor temperature drops below 10, it needs to be moved indoors. When cultivating orchids, you can water the plants once every 3 days, and fertilize the orchids every 10-30 days, and then put them in a astigmatism environment to meet its growth needs and make the plants grow more vigorously.

degrees

Orchid is a very cold plant, it can only tolerate a low temperature of 10 degrees, if the outdoor temperature is below 10 degrees, you need to move the plant indoors to avoid the orchid from being frostbitten by the cold, thus affecting the normal growth of the plant.

2. Provide moisture

In the process of orchid growth, the demand for water is greater, you can water the plant every 3 days, and keep the soil moist when watering, which is conducive to better absorption of water and healthy growth of orchids.

3. Provide nutrients

In the long-term growth of orchids, fertilizer can be applied to the plant every 10-30 days to provide the nutrients needed for the growth of the orchid, so that the plant grows more vigorously, but when fertilizing, the fertilizer needs to be diluted to avoid the fertilizer concentration is too high, resulting in the root system of the orchid being burned.

4. Prune

When cultivating orchids, they need to be pruned, and sharp scissors can be used to cut off the withered leaves of the plant to reduce the consumption of nutrients by the orchid, and then put it in a cool environment to maintain it, so as to promote the rapid recovery of the plant.

Growing orchids indoors in winter is not ventilated, so you need to keep the orchids away from heat sources and place them in a dry and shady corner. Also avoid direct light on the orchid. Cultivated orchids need to be watered every three days in spring and autumn, once every half a month in winter, and once a day in summer.

In winter, indoor orchids are not ventilated, in order to avoid the orchid from rotting due to unventilated environment in a high temperature and humid environment. You need to place it away from the heat source and place it in a dry and cool place in the corner. At the same time, avoiding sunlight on the orchid will cause the orchid to photosynthesize, but it will not be able to breathe.

It is recommended to grow orchids indoors in winter, you need to open the windows and ensure good air circulation. Although orchids prefer a humid and warm environment, the lack of air circulation can easily cause orchids to breed bacteria and cause orchid diseases.

To grow orchids, you need to prepare loose and fertile soil with good drainage and air permeability. Orchids prefer a warm, humid environment and do not require much light, so they need to be placed in semi-shade to receive scattered light. Spring, autumn and winter allow it to receive scattered light, and summer is hot and needs proper shade.

Orchids have a higher need for water, but they are not tolerant of stagnant water, and need to be watered every three days in spring and autumn, once every half a month in winter, and once a day in summer. This ensures that the orchid has sufficient water and also avoids water accumulation in the potting soil, which can lead to rot of the orchid roots.

It is best to reach about 25 degrees outdoors, and orchids can be grown. Orchids are planted in fertile nutrient soil. Supplement some organic fertilizer, the concentration of fertilizer should not be too high, do not water after fertilization, and then fertilize once every half month.

It roughly needs to be between 20 and 30 degrees during the day and around 16 to 20 degrees at night. A greenhouse should often open windows for ventilation and gradually increase the light intensity. The second is to complete the management process of soil change, repotting and transplanting indoors.

Third, the orchid potted plants that have just come out of the room need to take necessary shade measures.

In winter, the weather is getting colder, and the orchids placed outdoors are easily attacked by cold snaps, so they must be moved indoors in a sunny place in time to maintain. If you live in a building, it is best to put the orchid pot on the closed balcony, which can ensure that the orchid has sufficient sunlight, which is extremely beneficial to the pregnant buds and flowering of the orchid.

After entering the room, the room temperature should be controlled between 5 and 15, which can be met by the average family. But the room temperature should not be too high, too high will cause slow growth of flower stems and poor bud development. Orchids like a warm and humid environment with good air circulation, the indoor stove in the north for heating, should keep the pot away from the fire, around noon on a sunny day, should open the window for ventilation, or place the pot outdoors in a sheltered place from the wind and sun.

It will freeze to death, and the temperature will be lower than ten degrees, and the orchid will wilt.

Orchid (scientific name: cymbidium ssp.).）：

Epiphytic or terrestrial herbs, leaves several to many, usually born at the base of the pseudobulb or on the lower nodes, in two rows, banded or rarely inverted-lanceolate to narrowly elliptic, the base is generally broadly sheathed and encloses the pseudobulb, and the nodes are related. The racemes have several or multiple flowers, and the colors are white, pure white, white-green, yellow-green, light yellow, light yellow-brown, yellow, red, blue, and purple.

The orchid in the traditional Chinese famous flower only refers to several species of native orchids distributed in the Chinese orchid genus, such as Chunlan, Huilan, Jianlan, Molan and Hanlan, which are commonly referred to as "Chinese orchids". This kind of orchid is very different from the tropical orchid with large and colorful flowers, no eye-catching showiness, no huge flowers and leaves, but it has a simple and quiet, elegant and noble temperament, which is very in line with the aesthetic standards of the Orientals. It has been cultivated in China for more than 1,000 years.

How can such a delicate plant as an orchid be put outside, it will freeze to death, and the temperature will be lower than ten degrees, and the orchid will wilt.
