How to maintain orchids in summer and how to maintain orchids in winter

The maintenance methods for summer orchids are as follows:1. More ventilation. Flower cultivation and ventilation is a compulsory course, plants want to grow well, ventilation must be good, which is why the plants raised outdoors are always more lush than the plants raised indoors, and they are easier to raise, that is, the ventilation is good.

2. Be shaded. Orchids must be shaded in summer, because in the season of high temperature in summer, ultraviolet rays are very strong, some sun-resistant flowers can be placed outside, some dormant semi-dormant plants are placed outside for a day, it is easy to die, orchids are also slow to grow in summer, even if there is no shortage of water in the sun, strong light irradiates its leaves are also prone to sunburn, and the leaves and leaves appear sunburned, and the whole ornamental value will be reduced, so it should be placed in a semi-shady place or under the tree, especially to avoid exposure to the sun at noon.

3. Prevent pests and diseases. Mosquitoes are flooded in summer, and it is a big green worm, and it is a variety of aphids and scale insects, raising orchids is not immune, orchids are not insect resistant, and it is easy to recruit some scale insects to lie on the leaves in summer, there are white and brown, just like a layer of film, and it will fall off with your hand, which will affect the appearance of the orchid. If it is not treated in time, it will also cause plant rot, so we raise orchids and spray them with insecticides every other month.

Orchid summer maintenance method:

Clause. 1. Watering should be appropriate.

The evaporation in summer is relatively large, the orchid has been in a state of growth, so watering should not be lacking, if the potting soil is dry, its root system may be short of water, which may affect the differentiation of flower buds, as far as possible until the surface of the potting soil is dry, directly watering can be done, you can also control the water a little, and a little water control will help the differentiation of flower buds.

Clause. Second, it is necessary to control the high temperature.

When the temperature is above 35 degrees in summer, the orchid root will stop growing, or grow particularly slowly, so try to control the temperature of the orchid, the temperature difference between the day and night in summer is the smallest, the night is cooler, it will grow, and it will consume too much nutrients, so try to control the high temperature for the orchid and don't let it run short, for example, in some flower sheds, close to the mountainous areas, the orchids will be moved to the mountainous areas to avoid the high temperature, and the temperature difference between the day and night in the mountains is larger, and there is a homeopathic difference between the consumption of day and night in the mountainsThe greater the temperature difference, the better it grows and blooms.

Clause. 3. Proper light seeing.

In summer, the orchid grows relatively slowly, and it should not be exposed to excessive sunlight, so it should be placed in a semi-shady place, preferably in a mottled shade place under the tree, or do a good job of shade on the balcony, so as not to damage its leaves.

Clause. Fourth, fertilization should be supplemented.

Summer is an important stage for orchid differentiation flower buds, fertilizer must keep up, otherwise the fertilizer is insufficient, the sprouts stop growing for a period of time, it will affect its flowering, summer fertilization try to supplement phosphorus and potassium fertilizers, such as Hua Duoduo No. 2 or potassium dihydrogen phosphate, each. Watering once or twice will help the flower buds to differentiate, and in autumn the flowers will bloom more.

Clause. Fifth, it is necessary to prevent pests and diseases.

Mosquitoes are flooded in summer, and it is a big green worm, and it is a variety of aphids and scale insects, raising orchids is not immune, orchids are not insect resistant, and it is easy to recruit some scale insects to lie on the leaves in summer, there are white and brown, just like a layer of film, and it will fall off with your hand, which will affect the appearance of the orchid. If it is not treated in time, it will also cause plant rot, so we raise orchids, spray it every other month with insecticide imidacloprid or aviridine insects, and the remaining roots or sprinkle some small white medicine to prevent it from appearing various insect eggs of pests and diseases, and prevent problems before they occur.

Indoor insulation, fertilizer control, watering, ventilation.

1. Indoor insulation, the weather is getting colder in winter, and the orchids placed outdoors are easily attacked by the cold snap, so they must be moved into a sunny place indoors in time for maintenance.

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.

2. Fertilizer control and brightness, orchids generally do not need to be fertilized during hibernation. The roots of orchids have root fungus symbiosis and generally need to be repotted every other year, and the soil is rich in nutrients, so there is no need to repot. However, for Chunlan, it will grow in winter, and it is necessary to replenish nutrients in time and spray a small amount of phosphorus and potassium fertilizer on the foliage.

3. Control watering "can not be dry in summer and autumn, and not wet in winter and spring", which is the experience of raising orchids summarized by predecessors. Orchids are mostly dormant in winter, requiring less water, and the potting soil is slightly moist.

If the potting soil is indeed very dry, it can be used for water spraying at a similar room temperature around noon on a sunny day to keep the potting soil slightly moist. Orchids should be watered with rain or snow, but if you use tap water, you can leave them dry for two days before using them.

4. Ventilation, orchids like a warm and humid environment with good air circulation, indoor stove heating in the north, the pot should be kept away from the fire, around noon on a sunny day, the window should be opened for ventilation, or the pot should be placed outdoors in a sheltered place from the wind and the sun.

Orchids that are placed on closed balconies for maintenance should also ensure air circulation and open windows frequently. But when the temperature drops sharply, close the windows immediately to prevent the orchid from freezing.

How many varieties of orchids are there:

According to incomplete statistics, there are a total of 800 genera and more than 20,000 species of orchids, which is the second largest plant family in the world. It seems huge, but as long as it is subdivided, it is still very clear.
