After the temperature rises in spring, it is necessary to change the pot of white orchid, young plant (once a year), shaped plant (2-3 years a time).
Priority should be given to the use of sandy soil with good drainage, porosity and rich humus as basin soil. Keep the heart soil of the root to change the basin.
Because the white orchid is the fleshy root, its ability of dry and wet resistance is not good, so it is not only afraid of water accumulation, but also afraid of water shortage of soil after germination of new buds.
When the temperature rises above 15 ℃ and is relatively stable, the white orchid can be placed in the light outside the balcony for cultivation. Pay attention to keep the pot soil moist, and start to apply fertilizer when new leaves grow.
The high temperature and strong light in summer are easy to accelerate the aging of white orchid leaves, at the same time, it is easy to cause drying of basin soil and insufficient water supply. Therefore, in summer, it is necessary to move white orchid to a semi shade place with sufficient light in the morning and evening for cultivation, and pay attention to keep the soil moist and thin fertilizer applied frequently.
To increase the humidity of the air, the measures of sprinkling water around and good ventilation should be taken.
Wait until the temperature drops at the end of summer, and then put the white orchid in the place with sufficient light for cultivation.
In autumn, the light intensity is weakened, and white orchids need to be placed in the sunny place to ensure sufficient light, and the amount of water and fertilizer should keep up.
After October, when the weather turns cool, the amount of water should be reduced and the fertilization should be stopped gradually.
In order to improve the cold resistance of brandy in autumn and prevent the occurrence of insect pests, it is necessary to put the white orchid in the low temperature outdoor for a period of time, but avoid being hit by frost. Immediately move into the balcony with sufficient light for cultivation before frost. When the temperature drops suddenly, we should take measures to prevent cold in time.
The cold resistance of white orchid is poor, and the temperature of winter cultivation should be kept above 5 ℃ - 8 ℃.
Winter is the semi dormancy period of white orchid. It is also necessary to ensure sufficient light, no fertilization, and keep the pot soil in the state of "no drying, no watering".
It is also the key to keep a smooth ventilation in winter, so as to prevent the occurrence of insects such as scale insects.
One year's careful care will make your white orchid become pure and pure. Because it is so beautiful and fragile, it can't be careless in maintenance.
