How to raise spring orchids in pot culture methods and points for attention of spring orchids

Cymbidium is a common flower variety in our country, which can be seen in many places in our country at present. Chunlan has a high ornamental value, and the main ornamental point lies in its flowers and leaves. Now there are many people who breed it, but before breeding, what we must be most concerned about is its breeding method.

How to raise potted Cymbidium

1. Soil. To use acidic soil to grow it, not alkaline, if it is a special culture soil, it is best to use orchid mud, or with rotten leaves and garden soil mixed well.

2. Temperature. It needs an atmosphere of 15 to 25 degrees. If it is from March to October, it should be 18 to 25 degrees. If it is from October to March of the following year, it should be 10-18 degrees. Severe winter can withstand a low temperature of minus 5-8 degrees, but it is best to have 3-8 degrees. It can be placed on the window facing south, so that the soil in the basin will not freeze.

Culture methods and matters needing attention of spring orchids

1. Culture methods:

1. The amount of water should be determined according to different stages, different stages of growth and different atmosphere. During the severe winter, it suspends its growth and wants to control watering, usually once every 5-7 days, and the soil is a little wet. If the soil is dry, it should be sprayed with water close to the temperature in the house when the weather is fine, but it cannot be irrigated. 2. Fertilizing can not use a large dose of fertilizer, it should be rotten first, organic fertilizer or special fertilizer can be used. When it grows buds, you only need to leave one of the healthiest and most beautiful buds, the rest can be cut off, and you can spray some special fertilizer for flowers, which can help it look more beautiful and prolong the time of flowering, and remove the flowers when they wither. Don't wait for it to fall naturally, which can reduce the loss of nutrients and make it easier to bloom in the coming year.

2. points for attention:

There is heating in the house in the north in the severe winter, which is not very good for the growth of its flower buds, so it is best to move it to the balcony outside the house. If it is planted in the south, high temperature and humidity, it does not need a lot of nutrients, the probability of germination is very high, can sprout three or four times a year.

What if the leaf tip of Chunlan is dry?

1. Suffer from cold. Orchids are not cold-resistant, we should be careful not to let it be attacked by sunset when the temperature drops at the end of autumn, and put it in a leeward and warmer position, otherwise the leaf tip will easily dry up or the leaf color will turn pale and yellow. After entering the winter, the temperature drops sharply, when the temperature is close to 0 ℃, the flowerpot should be moved to a place with good indoor ventilation and sunlight for maintenance. When spring comes, after the climate warms up slightly, other flowers have begun to move outdoors, but Chunlan should not be in too much of a hurry to move outdoors. Because the climate is changeable, it is easy to cool down, even spring frost or strong wind. We can't let it suffer from sudden cold damage.

2. Improper watering. Keep the basin soil moist in autumn to prevent excessive dryness, causing leaf tip withering. Don't water too much in winter to prevent frostbite and rotting roots. When a plant with a withered leaf tip has appeared but is not serious, use sharp scissors (sterilized with alcohol) and cut it off 1 cm away from the withered tip. Do not keep any dead leaves on the basin, and then spray the medicine.

Diseases and insect pests of Cymbidium and its control

1. White silk disease: it mostly occurs in the plum rain season. Should pay attention to ventilation and light, basin soil drainage is good to prevent, after the disease can be removed with bacteria basin soil, sprinkled with pentachloronitrobenzene powder or lime can be.

2. Anthrax: it occurs all the year round, especially in the high temperature and rainy season. In addition to improving environmental conditions, during the onset period, 50% methyl topiramate wettable powder 800-1500 times solution can be sprayed for 7-10 days, and then supplemented with 1% equal volume Bordeaux solution, once every semimonthly.

In fact, the method of spring orchid culture is not difficult, when breeding, we must pay attention to the proportion of soil, and we also need to strengthen the conservation of fertilizer and water in the later stage of culture. If the leaf tip dries up when the spring orchid is cultured, it is necessary to find out the cause from the root and then solve it thoroughly.
