The weather is cold, what to do with the orchids?

Orchids are hardy plants! Chunlan and Whelan can tolerate low temperatures as low as minus five degrees! Hanlan and Mo Lan can tolerate low temperatures of no less than five degrees!

Orchids need low temperatures in winter to differentiate their flower buds! Chunlan and Huilan should not exceed 10 degrees as well! Hanlan and Mo Lan should not exceed fifteen degrees as well!

But no orchid is afraid of frost! As long as the frost is prevented, there is no need to move the house to water the orchid plant.

There are three ways to supply water to the roots of orchid plants: irrigation, sprinkling (drenching), and soaking. "Irrigation" is to fill water along the edge of the pot with a kettle, the advantage of this method is that the water will not be poured into the center of the leaf, the disadvantage is that the watering speed is slow, and it is difficult to water thoroughly, and it is necessary to repeatedly irrigate many times to achieve the effect of watering thoroughly.

"Sprinkling" is to use a watering can or shower head to sprinkle water, spray the entire orchid environment, let the water seep from the soil surface to the orchid root, moisten the orchid pot, the advantage of this method is that the water can be poured through the entire orchid pot, the disadvantage is that the water is easy to splash into the heart of the leaf, to be careful to use, otherwise it will be rotten. "Immersion" is to soak three-quarters of the orchid pot in water together with the planting material, the advantage is that the water can be soaked, and the disadvantage is that it is easy to spread bacteria, and it is labor-intensive and time-consuming. Orchid masters often use a mixture of these three methods, and the effect is very ideal.

There are two ways to supply water to orchid leaves: spraying and humidifying. "Spraying" is to use a sprayer to spray out a fine mist, which is scattered directly on the orchid leaves, so that the orchid leaves can be absorbed into the body through the pores.

"Humidification" is to increase the humidity of the air so that the orchid leaves can absorb it. There are several ways to humidify: one is to use a humidifier to clear the fog and increase the humidity of the space; The second is to increase the water surface, set up more water basins under the blue frame, and increase the humidity of the space by water volatilization; the third is to artificially simulate rainfall, splash water mist, and increase air humidity; In addition, an aeration pump can also be used to help volatilize water vapor in the discharge basin.

5-8 degrees indoors, and 3 degrees or more outdoors. Such a temperature will not cause harm to any Guolan, so there is no need to care. It's just that this winter is rainy in the south, and attention should be paid to proper shelter from the rain, because the soil is easy to rot roots at low temperature and high humidity, which also has a great impact on flower buds.

As for the application of pesticides, it is even more unnecessary, such temperatures, diseases, insects, bacteria and viruses will not have any vitality, so there is no need to consider it. There is no way to tell you how often to water, the principle is not to dry or not to water, and to water thoroughly.

Orchids like shade and are afraid of direct sunlight; Prefer moisture, avoid dryness; It likes to be fertile and rich in a lot of humus; A well-ventilated environment.

The place where the orchid is placed is very important, and it directly affects the growth and development of the orchid. Orchids are generally placed in the open field in spring, summer, and autumn (in the shade of the open field in summer) and indoors in winter. It is best to be outside in an open area with humid air.

There should be plenty of light indoors, preferably facing south. In this way, it is beneficial for orchids to grow. It is best to place the orchid basin on a wooden frame or table, not on the ground.

Orchid is a plant that likes a warm and humid environment, and the high temperature in summer makes the orchid leaves easily damaged by heat, resulting in poor plant growth and shortened flowering period. To cool down the orchid, the stove hand can do the following:

1.Avoid direct sunlight: Orchids love light, but the sun is strong in summer, so you need to avoid direct exposure to orchids. Orchids can be placed in a well-ventilated, half-shaded and half-sunny location, or shaded by shade nets, blinds, etc.

2.Appropriately increase air humidity: In summer, the temperature is high and the air is dry, which is easy to make the orchid leaves evapotranspire too much water, resulting in wilting, yellowing and other problems.

You can place water hidden pots, sprayers, etc. around the orchid to increase air humidity, or you can cover the orchid leaves with a wet towel to help the orchid cool down and moisturize.

3.Reduce the frequency of fertilization and fertilizer concentration: Orchids grow faster due to high temperatures in summer, but too much fertilizer will increase the metabolic burden of plants and affect the healthy growth of orchids.

In order to avoid excessive fertilizer, it is necessary to appropriately reduce the number of fertilization and fertilizer concentration to ensure the normal growth of orchids.

4.Protection against heavy rain or strong winds: Summer is the thunderstorm season, strong winds and heavy rains can easily cause damage to orchids, and you need to pay attention to protection. You can place the orchid in a safe place, and clean up the problems such as stagnant water and lodging in time.

In summary, the above measures can be used to cool the orchid in summer and reduce the impact of heat damage on the orchid.

1. Root treatment.

Newly bought orchids should be spread out and dried to observe whether their roots are rotten or wrong. If there is, it needs to be deducted in time. In addition, the roots of orchids need to be soaked in a 5% potassium permanganate solution for about half an hour to kill the bacteria and fungi that multiply on them.

After that, it can be dried and eaten.

2. Less fertilization.

Under normal circumstances, merchants will supplement nutrition scientifically and reasonably, so don't consider fertilizing just after buying it, so that the orchid can adapt to the surrounding environment as soon as possible. Just spray plenty of water to keep the soil moist. Half a month later, add thin fertilizer according to the actual situation.

3. Ensure that the environment is warm.

Orchids prefer a warm and humid environment, and the indoor temperature is best kept at around 20 degrees Celsius. Sin helps them adapt to their new circumstances. Both too high and too low temperatures may cause its growth to stagnate, and even the leaves turn yellow and fall off, seriously affecting its aesthetics.

Fourth, watering at the right time.

Newly planted orchids in pots should be careful not to be watered immediately, and the slag should be left for a period of time to allow it to adapt to the new soil environment. When the soil is visibly dry, water for the first time. Water thoroughly, but be careful not to plug the bloads with too much water.

1. Watering: Orchids should be watered every 1-2 days during the vigorous growth period. 2. Ventilation:

Open windows frequently for ventilation to ensure that the orchid receives fresh air. 3. Fertilization: Orchid peanuts need to be topped with fully decomposed thin cake fertilizer water for a long time.

4. Light: Usually put the orchid on the balcony covered by a bamboo curtain, and in winter, you can move it outdoors to receive astigmatism.

1. Reasonable watering

Orchid in the maintenance process, need to be watered every 1-2 days during its vigorous growth period, high temperature in summer, usually watered once a day in the early morning and evening, do not water at noon, and in the rainy season according to the amount of rain and the humidity of the potting soil to flexibly grasp the amount of watering, in winter you can water every 5-7 days.

2. Ventilation

Orchids cultivated in greenhouses and greenhouses should be equipped with suction and exhaust fans to promote air circulation and reasonably adjust humidity, while for indoor maintenance of orchids, windows should be opened frequently for ventilation to ensure that the plants receive fresh air and prevent excessive heat and breeding diseases and pests.

3. Scientific fertilization

In the growth period of orchids, it is necessary to apply fully decomposed thin cake fertilizer water, or compound fertilizer mixed with urea and potassium dihydrogen phosphate, and keep it applied every 15-20 days, and spray 2-3 times of plant ash water on the foliar surface of orchids before flowering to flowering period to promote the development of roots, stems and flowers.

4. Control the lighting

Orchids like shade, afraid of strong light, in spring, summer, autumn need to shade the plants, domestic orchids, can be placed on the balcony with bamboo curtains or under the eaves, generally 9 am to 6 pm to be placed in a cool place, winter can be moved to the outside to receive astigmatism.

1. The ambient temperature of planting orchids should be suitable: orchids generally grow well in an environment of 25 to 30 degrees, but not all orchids are like this, and the temperature required by different varieties is different, and we need to depend on the situation;

2. Do a good job of watering: know certain skills when watering orchids, water more when they are vigorous, and less when they enter the dormant period; Flower pots are larger, plants are smaller and less watered, flower pots are smaller, plants are larger and should be watered more; Water more in dry and hot weather, and less water in rainy weather; In short, watering orchids depends on the weather, season, species, and other factors.

3. Choose the right pot and the right soil: When planting orchids, it is recommended that you choose a tile pot with a diameter of about 25 cm; You can prepare the soil yourself, and of course, you can also buy ready-made nutrient soil.

Orchids should be protected from rain

Orchids can be showered with light rain, but avoid mildew rain, showers, or continuous rain. In the mildew rainy season, it is especially necessary to do a good job of rain prevention. From late June to mid-September, showers are common.

If the rain is short and the rainfall is small, you should water more in the evening to let the heat in the pot be discharged, otherwise the orchid will be damaged, and even the roots will rot and die.

If the sun comes out again after a shower, shade should be taken in time to prevent the rise of heat on the ground and affect the growth of orchids. In the rainy season, it is the stage when orchids extract leaf buds, and if the potting soil is too warm, the leaf buds will not grow well or cause diseases. At this time, a small amount of plant ash can be sprinkled to adjust the moisture of the potting soil.
