White orchid is an evergreen native plant of Orchidaceae and Michelia. It is a natural cross between Magnolia and Michelia. It grows in South China, Southwest China and Southeast Asia, and can grow to a height of 10 meters and 13 meters. White orchids like light, avoid stagnant water, not cold-resistant, but also afraid of high temperature, suitable for slightly acidic soil. Love high dryness, avoid low dampness, waterlogging is easy to rot roots. The sandy soil, which is fertile, well drained and slightly acidic, can also grow on weakly alkaline soil.

1. The choice of flowerpot and 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 quantitative amount of granular soil of different sizes to facilitate water seepage and air permeability.

2. The operation method of changing 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. When operating, you should wait for the pot to dry, tilt the pot (jar) slowly (or upside down), hold the basin by hand, hold the plant firmly by hand, 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.

3. Planting position. 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. The temperature in summer is high, so you should choose a sunshade net or build a simple shade shed as appropriate, so that the white orchid can shine on the morning sun and avoid the strong light in the summer afternoon (so as not to burn branches and leaves due to exposure).

4. 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.

5. Fertilization. During the vigorous period of white orchid growth (usually in May, June or July and August of each year), one flower fertilizer should be applied to the white orchid every half a month or so, or a little nitrogen, phosphorus and potassium compound fertilizer should be applied at about 20, 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 because of 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 are irrigated every 4 days from July to September, once every 6 days from July to September, and once after several times of fertilizer application.
