What are the culture methods and matters needing attention of white orchids?

White orchid flowers are white and fragrant, blooming in summer and autumn, with long flowering period and thick green leaves. They are famous garden ornamental trees, and most of them are street trees. Flowers can extract essence or smoked tea, can also be extracted for medicinal use, there are qi turbid, equivalent to treating cough. So what are the methods of white orchid culture and matters needing attention?

Soil

Family potted white orchids should be cultivated in soils that are loose, permeable and rich in humus. Usually choose tile basin with good air permeability, purple sand basin (cylinder) or plastic basin with more bottom holes. The soil in the basin had better have a certain amount of granular soil of different sizes to facilitate water seepage and air permeability.

Change the basin

According to the crown size and age of the white orchid, the pots and vats of the appropriate size should be replaced to facilitate the vigorous growth of the plant. During the operation, you should wait for the pot to dry, tilt the pot (jar) slowly (or upside down), hold the basin in one hand, grasp the plant in the other, and pour out the white orchid and move it into the new pot. The new basin (tank) should be padded with a small amount of loose soil in advance, then irrigated thoroughly, and the planting can be stable.

Light

From March to April every year, the pots and jars planted with white orchids are removed from the outside and placed in a sunny place. High temperature in summer, should be appropriate to choose a sunshade net or build a simple shade, so that the white orchid can not only shine on the morning sun, but also avoid the strong light in the summer afternoon (so as not to burn branches and leaves due to exposure). The Beginning of Summer moved back and forth to the outdoors, to be placed in the sunny ventilation place, the sunshine should be more than 6 hours. Only when there is enough light, can it grow well. If there is not enough light, it will grow branches and leaves, blossom less or not. And in the hot summer season, the sun intensity, should be a little shade, so as not to burn leaves and tender stems.

Fertilizer application

In the vigorous period of white orchid growth (usually in May, June or July and August of each year), the white orchid should be given flower fertilizer every half a month or so, or a little nitrogen, phosphorus and potassium compound fertilizer should be applied at intervals of about 20 grams, 2 to 6 grams at a time.

The specific operation is: first use a small shovel to draw several vertical and horizontal ditches of the soil in the basin, then slowly spread the fertilizer into the ditch, then cover it with the topsoil in the basin, and pour some water. Make the fertilizer gradually infiltrate into the root of the plant with each watering. Do not spread the fertilizer directly to the root, so as not to "burn the root" due to the heavy fertilizer effect of the soil around the root. It is better to apply thin fertilizer frequently, cake fertilizer is better, no fertilizer is applied in winter, fertilizer and water is irrigated every 3-4 days from new buds to June, once every 5-6 days from July to September, and should be stopped after several times of fertilizer application.

From moving outdoors to the end of June, alum fertilizer water was irrigated every 7-10 days to make the soil slightly acidic. At flowering stage, one more available phosphate fertilizer can be applied to make it smell incense.

Watering

Proper watering is the key to the conservation of white orchids. White orchids should not be overwatered or overwatered. The correct watering method should be to moisten the soil in the basin at one time, but it is not necessary to water the soil in the basin when it is slightly dry. Remember not to water every day, but you can often spray water on the leaves with a small spray can. In summer, water should be irrigated not less than three or four times a month (plus spraying water on the leaves). The easier way to master is to water the white orchid as long as you see its leaves drooping. It is watered two or three times a month in autumn and once or twice a month in winter.

Because of the fleshy root system, it is afraid of stagnant water and is not resistant to dryness. Irrigate once out of the house in spring, then once every other day; once in the morning and evening in summer, spray foliar water if it is too dry; once every 2-3 days in autumn; buckle water in winter, as long as the basin soil is slightly moist; pour the stagnant water in time after rain. Prevent smoke pollution, keep the leaf surface clean, and spray wash the leaf surface if necessary, so as to facilitate the normal development and growth of the plant.

Temperature

Not cold-resistant, except for South China, all other areas should enter the room for maintenance in winter, the lowest room temperature should be kept above 5 ℃, and the time to leave the room should be from Qingming Festival to Grain Rain. Do a good job of anti-freezing and warm work, the indoor temperature is maintained above 12 degrees during the day and not less than 6 degrees at night, otherwise it is vulnerable to cold damage. Circulate the air and keep the soil moist in order to survive the winter safely.

Pruning

Before entering the house, the withered branches, diseased branches, overgrown proud branches and over-dense branches should be removed to minimize the nutrient consumption of the plant; when leaving the room, the old leaves in the lower part of the branches can be properly removed, which is beneficial to the growth of new branches. In addition, it is necessary to pay attention to aphids and other harm to twigs and shoots, which must be controlled in time.
