Maintenance technology of white orchid

Magnolia flowers like sunshine and warm and humid growth environment, and their maintenance and management should be based on different climatic conditions and local conditions.

1. Flowerpot, 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.

2. Location of planting and storage

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). Whenever you encounter continuous drizzle in autumn or heavy rain in summer, pots and pots should be placed in shelter in advance to avoid rotting roots due to excessive stagnant water. In winter, you should choose to place it in the room where the sun can shine and the seal is good. In order to prevent frostbite, the pots and cylinders planted with white orchids should be covered with plastic film.

3. Pruning

Potted white orchids should choose the appropriate height, cut off the terminal buds and cut some side branches with shears. After the terminal bud is cut off, it is beneficial to how long the lateral branches are, and the longer the buds are, the more they bloom.

4. prevention and control of diseases and insect pests

White orchids usually have leaf spot disease, fungal rot, aphid disease and so on. Aphids can be caught and eliminated directly. For the leaves with the appearance of bacteria, the diluted carbendazim and methamidone solution can be sprayed and sterilized.

5. 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.

6. Fertilization

During the vigorous period of white orchid growth (usually in May, June or July and August of each year), the white orchid should be fertilized with flower fertilizer every half a month or so, or a little nitrogen, phosphorus and potassium compound fertilizer should be applied at a time of 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.

7. 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.
